ANSI Z87.1 Defined

ANSI is an acronym for the American National Standards Institute, a nonprofit organization the the primary mission to…

Enhance both the global competitiveness of U.S. business and the U.S. quality of life by promoting and facilitating voluntary consensus standards and conformity assessment systems and safeguarding their integrity.

In other words, ANSI creates uniform testing standards and guidelines for a variety of products and equipment used by businesses in nearly every sector.

The Z87.1 portion references the standard for personal Occupational and Educational Personal Eye and Face Protection Devices. These standards help ensure personal eye and face protection devices provide the necessary protection from impact, non-ionizing radiation, and liquid splash exposures.

The ANSI Z87.1 standard has been updated twice since 2003, with revisions in 2010 and 2015. These updates focus on product performance and attempt to harmonize with international standards while keeping the needs of end users in mind with consideration to workplace hazards and regulatory obligations.

The current ANSI.1-2015 standard continues to differentiate protectors based on specific risks with additional emphasis placed on enabling users to select the appropriate protector based on their environment and the hazard.

What Are The General Requirements For ANSI Z87.1

Since most people have never read the ANSI Z87.1 document, they may not fully understand what this certification covers. The ANSI Z87.1 certification helps in this effort by providing a certification system organized based on encountered hazards.

This standard means the choice of safety eyewear revolves around what best represents the protection needed for the specific hazards encountered in the workplace. The most common hazards include:

  • Blunt impact
  • Radiation
  • Splashes and droplets
  • Dust
  • Small dust particles

Most safety eyewear manufacturers now provide packaging and product information revolving around how products meet these standards. Note that prescription safety lenses are also allowed under this standard. Previously, they had to be a certain thickness, but thinner prescription lenses are now allowed if they meet high-impact testing requirements.

What Is The Testing Processes

ANSI Z87.1 certified safety glasses undergo intensive testing to ensure they’ll protect eyes as expected. Tests include…

  • Basic and high-impact for lenses and frames.
  • Exposure to non-ionizing radiation and chemicals.
  • Durability to flammables and corrosion.

The following video from Edge Eyewear does an excellent job demonstrating the different tests performed on safety eyewear. After seeing how badly non-safety-rated eyewear fails these basic tests, you’ll only want to purchase ANSI-Z87.1 rated eyewear.


What Are The Product Markings

Starting in 2010 with additional updates in 2015, the ANSI Z87.1 standard requires efficient and easy-to-understand lens & frame markings. These markings help make the selection process simpler and increases compliance. Those product markings indicate ratings in the following areas:

  • Impact: “Z87+” indicates high-velocity impact, and “Z87” alone means basic impact
  • Splash and droplet: D3 for splash and droplet and D4 for dust
  • Fine dust: D5
  • Welding: W plus the shade number
  • UV: U plus the scale number
  • Infrared light: R plus the scale number
  • Visible light filter: L plus the scale number
  • Prescription: Z87-2 on the front of the front of the frame and on both temples
  • Head size: H indicates products designed for smaller head sizes
  • Other: V for photochromic and S for special lens tint

All safety markings for ANSI Z87.1-2015 safety eyewear must be permanently and clearly marked on the frame or lens. This marking requirement includes goggles and face shields as well as safety glasses.

Product Marking Examples

ANSI Z87 Product Markings

ANSI Z87.1-2015 product markings on a pair of Bolle Safety Glasses.

The image above shows a pair of Bolle Safety Glasses with the new ANSI Z87.1-2015 product marking requirements. The marking is broken down as follows…

  • “Z87+” indicates eyewear meets the high-velocity impact requirement.
  • “U6” means the eyewear has a UV rating of 6, which is the highest rating.
  • “S” indicates a special lens tint because these glasses feature Bolle’s ESP lens.

You may encounter safety eyewear with only “Z87” or the manufacturer’s mark with a “+” stamped on the lens or frame. These products, produce before of just after the 2010 standard, are still safe to use. They still meet ANSI Z87.1 high-velocity impact safety standards, but they don’t have the new product marking requirements from the recent 2010 and 2015 standards.


The temple arm from an Oakley M-Frame 2.0 is marked with Z87 to indicate it’s ANSI Z87.1 certified.


Hazard exposure able to cause serious eye injury involves workers in almost every industry. When combined with 100% compliance to a mandatory eye protection program, the right safety eyewear based on the current ANSI Z87.1-2015 safety standards helps ensure that doesn’t happen.

        hello Michael, i have a pair of Jackson nemesis sunglasses and it says that protec 99.9% against uv. I would like to know if this kind of sunglasses has 400 uv filter… what do you think ??

        • Jeff April 12, 2018 at 2:17 pm - Reply

          Camilo, UV400 is a specific filter or lens coating applied to boost the UV protection of sunglasses. It implies, and it supposed to mean, that the lens blocks all light up to 400nm (nanometers). This isn’t always the case, however. The UV part of the spectrum ends around 385 or so, and some coatings will block only up to that point which, in theory, is all that’s really necessary. At 400nm, you’re actually into visible Violet, part of the Blue light range, and it’s still good to block some of that for improved visual clarity. Polycarbonate inherently blocks 99.9% of UV light anyway, so you often won’t find UV400 added to this. Many sunglasses on the market use other materials, such as CR39 or some cheaper “plastic” that does not block as much UV light, making it more necessary to add a filter. Your Jackson Nemesis has polycarbonate lenses, and do not need the UV400 filter.

      Can they be used for a solar eclipse?

      • Michael Eldridge August 18, 2017 at 3:20 pm - Reply

        Hi Jesse,

        Thanks for the question.

        The ANSI Z87.1-2015 standard has nothing to do with eclipse viewing. With that being said, the only safety glasses that are approved for viewing a solar eclipse must have Shade 14 or higher welding lenses. No other lens color is recommended for viewing a solar eclipse because the tinting is not dark enough. Viewing a solar eclipse with eyewear containing any lens tint other than Shade 14 will cause severe damage to your eyes.

        I highly recommend you use Solar Eclipse Eyewear that is ISO 12312-2 certified. You can find more information about certified Solar Eclipse Eyewear at American Paper Optics.

            Hi Eduardo,

            That’s correct. A shade 5 lens is not dark enough to watch a solar eclipse. You need a shade 14 or higher lens to be safe.

          • Michael Eldridge August 20, 2017 at 11:00 pm

            Hi Eduardo,

            Correct, an IR5 or W5 lens isn’t dark enough to view a solar eclipse. You need a lens with +W14 (weld shade 14) to safely view the sun tomorrow.

          So how do we know what shade number our glasses are? I bought 3m pro 400 Series for the eclipse,but no where on the package says the shade number.

          • Michael Eldridge August 20, 2017 at 12:46 pm

            Hi Rose,

            The lenses should be stamped with 3M+W14. The 3M is the brand/manufacturer mark, the “+” indicates the lenses are high-impact certified, and the “W14” indicates the lens tint is Welding Shade 14. Any other combination is not dark enough and shouldn’t be used to watch a solar eclipse.

            Without knowing the actual Shade number, I can’t verify your welding mask is safe to use. Some welding masks use Shade 10, 12, 13, 14, etc. And you need Shade 14 at a minimum to safely view a solar eclipse. I highly recommend you find a pair of Shade 14 Safety Glasses, welding mask or ISO 12312-2 certified Solar Eclipse Eyewear.

            No. It’s not recommended to modify your eyewear to watch a solar eclipse. You have no way to measure or verify the lens modification will actually provide the level of protection that you need to view a solar eclipse.

            To avoid serious eye injury only use certified Shade 14 welding lenses or ISO certified Solar Eyewear.

    Customer is looking for safety glasses with ANSI Z87+U6, does ANSI Z87.1-2010 include/cover this specification ANSI Z87+U6?

    • Michael Eldridge August 18, 2016 at 7:47 pm - Reply

      Hi Jim,

      Thanks for submitting your question.

      Yes, ANSI Z87.1-2010 does reference the “U6” markings. Here’s how it’s broken down. The ANSI Z87+ portion means the safety glasses are approved for impact. The U indicates Ultraviolet Filter and the 6 represents the highest level filter (UV Scale is 2-6).

      These “new” eye protection markings were introduced in the 2010 standard and are now required in the recent 2015 update. However, it may take a while for manufacturers to completely phase in these new marking requirements.

    Can you tell me what the U1-6 scale for UV protection signifies. Is it the percent of UV blocked or does it specify the wavelengths filtered. I have a face shield used in a laboratory to protect against 312nm UV with the code ANSI Z87 but no “U” scale number. How do I know it does block this wavelength or UV at all?

    • Michael Eldridge September 6, 2016 at 2:17 pm - Reply

      Hello and thank you for the question.

      The ANSI Z87.1-2015 standard defines UV radiation as follows: Ultraviolet Radiation (UV). Electromagnetic energy with wavelengths from 200 to 380 nanometers.

      The UV Scale uses a rather complicated mathematical formula, however, for simplicity, it’s divided into two wavelength categories, far and near.

      Far-ultraviolet is defined as; Transmittance of optical radiation with wavelengths from 200 to 315 nanometers weighted by its ability to damage the cornea.

      Near-ultraviolet is defined as; Transmittance of optical radiation with wavelengths from 315 to 380 nanometers.

      UV Filter Transmittance:
      U2: Max Effective Far UV= .1% / Max Near UV= 3.7%
      U2.5: Max Effective Far UV= .1% / Max Near UV= 2.3%
      U3: Max Effective Far UV= .07% / Max Near UV= 1.4%
      U4: Max Effective Far UV= .04% / Max Near UV= .5%
      U5: Max Effective Far UV= .02% / Max Near UV= .2%
      U6: Max Effective Far UV= .01% / Max Near UV= .1%

      Some products, such as laser safety glasses, will have wavelength protection ranges stamped or printed on the lens. Your face shield probably doesn’t have this information, but its worth checking.

      If your face shield lens is made from polycarbonate, you’re probably in good shape. Polycarbonate naturally blocks 99.9% of harmful UV radiation. However, I recommend contacting the manufacturer of the face shield to be certain you’re protected.

      The new 2015 marking requirements are still being phased in, so there is no guarantee a new face shield will show the “U” scale number.

  5. R Heathcott September 8, 2016 at 3:22 am - Reply


    Thanks for your reply about the “U” scale number etc.

    The shield I have is a Crews face shield with the marking ANSI Z87 on it. It looks like the one you have for sale on your website with SKU 103WFS. It has the blue top and looks just the same but I can’t find a SKU number on it.
    Ours is several years old. I note that your advertised one is Polycarbonate. Do you know whether all Crews face shields that look like this one would be polycarbonate?

    Thanks for your help.

    • Michael Eldridge September 8, 2016 at 6:37 pm - Reply

      The Crews Head Gear can accommodate most standard face shields no matter what brand. This adaptability makes it tough to know what face shield is attached to your Crews Head Gear. Not all face shields are made from polycarbonate, so there is a possibility that yours doesn’t block UV light. Currently, Crews offers several face shield styles and materials. Face shields made from PETG look similar to polycarbonate, but are primarily used for liquid splash protection and they usually don’t block UV radiation.

      Honestly, I think your best option is to purchase a polycarbonate replacement face shield.

      Please let me know if you have any other questions or concerns.

      Hi Sandy,

      Yes, the frame and lens should be marked with “Z87+” to indicate compliance with the high-velocity impact standards. Older models of safety eyewear may only have “Z-87” or “+” on the lens or frame.

    • Michael Eldridge September 9, 2016 at 1:10 pm - Reply

      Hi Edward,

      Thank you for your question.

      The 500 fps you’re exposed to exceeds the Z87+ high-impact testing standard. The ANSI Z87.1-2015 high-impact velocity test consists of a 1/4″ steel ball shot at 150 fps, which is around 102 mph. Chances are most polycarbonate lenses may survive a 500 fps impact, but they haven’t been officially tested. In my opinion, it’s not worth the risk!

      You should seriously consider wearing ballistic rated eyewear because they’re tested using the US Military standards for impact protection (MIL-PRF-32432). In brief, the U.S. military standard requires that ballistic eyewear must be able to withstand up to a .15 caliber at 640 fps for spectacles and .22 caliber at 550-560 fps for goggles.

      The objects mass is just as important as it’s velocity. A heavier object will cause more damage than a lighter object moving at the same speed.

      Please keep in mind that safety glasses are not designed to protect you from all impact hazards. Make sure you evaluate the potential hazards in your workplace because you may need to wear ballistic rated goggles or even add a face shield.

      Thanks again for your excellent question. Please let me know if you have any other issues or concerns.

    Hi Michael. To what maximum temperature are the Z87.1 glasses exposed to during testing? I am concerned about potential Arc Flash during electrical work. Thank you.

    • Michael Eldridge September 15, 2016 at 2:38 pm - Reply

      Hi Majid,

      Thank you for the question.

      During the ANSI Z87.1-2015 certification process, all safety eyewear is subjected to an Ignition Test. Safety glasses are touched by a thermocouple rod that’s been heated to 650 Celcius or 1202 Fahrenheit for five seconds. The purpose of this test is to ensure the protector’s material is resistant to ignition. With that said, melting is expected for polycarbonate and plastic frame materials at those temperatures. Arc flash temperatures can reach 35,000 degrees Fahrenheit!

      Arc Flash is a very dangerous hazard! You should always wear the appropriate safety equipment when arc flash is a possibility. OSHA came out with some new regulations for arc flash safety in 2015. Make sure you take the time to familiarize yourself with these new regulations. I also recommend you do some research on the appropriate protective gear required for each arc flash category.

            Hi Sandy,

            Thanks for clarifying.

            The aim of the ignition test is to ensure protective eyewear isn’t flammable. During the test, the eyewear is in contact with an arm mounted at 650 °C. The eyewear is compliant if it doesn’t catch fire, and if it does not continue to glow after the flame source has been removed. You can find more details in the actual ANSI Z87.1-2015 document, which can be purchased here.

            Hi Sandy,

            You are correct about the safety glasses melting due to the high temperatures. The ignition test is to ensure the eyewear doesn’t burst into flames or continues to burn after the heat source is removed.

      Hi Rey,

      Thanks for your question.

      The E+S markings on the lenses of your Edge safety glasses are used to indicate the following:

      • E = The manufacturer’s mark for Edge.
      • + = The designated ANSI Z87.1 marking for “impact-rated”.
      • S = The designated marking for “special purpose lens”.

      Since you have the “S” marking on your safety glasses, you must have one of Edge’s unique lens tints.

      Hi Patrick,

      Thank you for the question.

      The vast majority of today’s safety glasses use polycarbonate lenses, which naturally blocks UV light, even with a clear lens. However, it would be nice if your safety glasses used the new marking requirements. Then you could be 100% confident that your safety glasses are providing the UV protection you need.

      If you know the brand/model name you can look for a specification sheet on the manufacturer’s website. The spec sheet will define the lens material and UV protection level.

      Please let me know if you have any other questions or concerns.

    Thanks Michael for your respons. That is a big help knowing polycarbonate is effective in blocking UV. Actually there is a name of Action Wear on the glasses but Googling that name brings up a lot of different distributors of glasses by that same name. Even with that there are no pictures of these same glasses in several sites I went into. Also there is no country of manufacture on the glasses where the glasses bought from Granger has China stamped in them.

      1. What would be the exact matching of EN ISO 166-1F from ANSI Standards for Safety Goggles?

      The European standard, EN166, allows for different levels of impact protection, radiation protection and optical clarity to exist with a given set of safety eyewear. In 166-1F, the 1 should indicate “Class 1 (High) optical quality suitable for regular use”. The “F” would indicate the strength of the lens and/or frame. Although it would be rare and strange to see, both the frame and lens could, in theory, be marked independently of each other with different levels of protection. An F rating means the lens and/or frame can withstand impacts against small objects travelling up to 45 meters per second, or 147.6 feet per second. This is very similar to but slightly less than, the 150 feet per second on which the ANSI Z87.1 standard is based.

      2. If a Safety Goggle is meeting ANSI Z87.1-2003, will it be meeting EN ISO 166-1F?


      3. what are the Updates happened from ANSI Z87.1-2003 to ANSI Z87.1-2015?

      Please read this document, which explains and summarizes the Z87.1 standard and its changes from 2003 to 2015.

      Hi Rikki,

      Thank you for the question.

      Yes, OSHA approved side shields will be marked with Z87+ or similar markings per the ANSI Z87.1-2015 standard.

      I highly recommend the Safety Optical brand as their quality and features are the best we’ve found. Their side shields are easy to install and available in multiple sizes and tints.

    What is the best rating out of z87.1 or z87+s

    • Michael Eldridge November 11, 2016 at 10:01 pm - Reply

      Hi Benjamin,

      Thanks for the question. Using the ANSI Z87.1-2015 standard, the “Z87.1” designation means the eyewear is rated for basic impact only. The “Z87+S” marking means the eyewear is rated for high-velocity impacts. Plus, the letter “S” indicates the eyewear has a special lens tint. Hope this helps clarify the difference.

    If a patient brings in a safety frame and wants non safety lenses in it. Is it legal to do so? Also, does scratching off the ANSI from the frame make it possible to legally put non safety lenses in it? Thank you

      Hi Mike,

      Thank you for the question.

      You can install any lens you want in a safety frame. However, non-safety lenses won’t have the required ANSI Z87.1-2015 markings, which makes them non-compliant. For prescription safety glasses to stay compliant with ANSI Z87.1 both the frame and lenses must have the required markings, per the ANSI Z87.1-20015 standard.

    Hello, My name is Edith and I work for the railroad. We have been given ANSI Z87.1-2015 safety glasses to wear. But a lot of of Engineers and Conductors are complaining about having a hard time seeing signals, it seems like they attract the glare of the LED lights, glasses are difficult to maintain clean. It seems like what ever gets on them, it can’t be clean they stay dirty. Also, there are a lot of complaints abou headaches, I’m assuming that’s because we’re trying to look over 200 feet down a length of a train with these glasses that in my opinion are making it hard to see.

    • Michael Eldridge November 14, 2016 at 4:00 pm - Reply

      Hello, Edith, and thank you for your question.

      When you stated that you had been given safety glasses to wear, I got the sense that this might be a recent thing. Perhaps your crew didn’t routinely wear them in the past or weren’t required to. If that is the case, then it’s not necessarily surprising that they are experiencing some of these issues. These complaints are not uncommon from newer users of safety eyewear.

      First, let’s establish that some people are more naturally sensitive than others regarding their eyesight. Eyewear of any kind may bother them, whether it’s viewing life through a lens, having some of their peripheral vision blocked, or simply having anything on their face or that close to their eyes.

      Next, the type of eyewear one selects (or is given) can vary significantly and this can also impact the wearer’s reaction and vision. Some safety glasses have large, thick, opaque frames that may completely block one’s peripheral vision. The reduced peripheral sight may give some a sense of tunnel vision or claustrophobia and make them uncomfortable. Others wearing the same style might feel safer, that nothing is getting through to their eyes. Many safety glasses do not use a traditional frame. Instead, their polycarbonate eyewear has a faux frame molded into the lens or even has no real discernible frame at all. If these glasses are lighter in color, such as with a Clear lens, then lights can be reflected or refracted off and through the edges of that frame or lens, and be seen as added glare. This issue is more often associated with cheaper wrap-around styles. Could this be what was given to you?

      You might consider eyewear that has an opaque frame (not transparent), such as a matte black, that will not only not cause the refraction of light but will also keep any reflected light to a low minimum. Depending on the time of day, night, or the lights you’re dealing with, you might also consider a lens that helps block a little glare. An Indoor/Outdoor lens is an excellent alternative to clear, providing your environment isn’t too dark. This lens usually has a light mirror coating over a clear base, and helps dim excessively bright lights or reduce some annoying glare. It is not a transitional lens but is viewed as a lens that simply works for both indoor and outdoor applications, given that it is a happy medium of light and dark, about 50-55% light transmission.

      There are many options, but here are some suggestions for such glasses:
      Bolle Silium Plus, Elvex Sonoma (light brown), Jackson Nemesis, Pyramex Venture 2, Pyramex Ever-Lite, Pyramex PMX-Torq

      I suspect there is an abundance of grease and oil around a railroad. It could even be airborne as a train passes, with fine particles landing on your lenses. These can accumulate slowly and likely become a mess to wipe off, as you’ve described. You might consider eyewear that is oleophobic, meaning it has a lens coating that resists oils. Some Oakley brand eyewear has such a coating, and they do offer a variety of ANSI Z87 certified safety glasses. A new, cheaper alternative is called Pacaya Lyviz, from Elvex, which is also oleophobic and hydrophobic. The Pacaya is offered in a Clear lens only at this time, but it does have foam padding that would prevent any glare from passing through the edges of the lens.

      Lastly, you might also look at one of our cleaning products. The Optic-Magic polish is not ideal for your oily environment, but the wipes might be. You’ll just want to be sure not to wipe to aggressively as the cleaning solution dries, as the wipes could become abrasive.

      If you have more questions, feel free to contact us. I hope this helps.

      To my knowledge, safety glasses/goggles don’t have expiration dates. However, you should always inspect safety eyewear before using it. If the eyewear shows signs of excessive use or damage, don’t use it. Also, don’t use any safety eyewear that doesn’t have the required frame and lens markings per the ANSI Z87.1-2015 standard.

    Michael, I teach automotive technology in a community college, and I have been trying to find a list of the operations that an auto mechanic does that requires safety glasses. We require our students to wear them at all times in our lab, but we are governed by state law, and I know the industry has different standards. I used to have a list with about 7 different operations, like grinding, refrigerant work, exhaust work, etc, but cannot find my old list or a current list.

      Hi Steve,

      Thank you for the question.

      Honestly, with today’s safety awareness practices, an official list may be hard to come by. While there are certain operations that clearly require safety glasses, there are plenty of hidden hazards in automotive repair. Many auto shops, factories and worksites use a “blanket” safety eyewear policy. Basically, if you’re physically in the work area, you need to wear eye protection. This type of policy improves safety compliance and helps prevent random eye injuries.

      Your understanding of the Z87-2+ is correct. However, more than likely, the “ARX” markings indicate the manufacturer/brand that created the eyewear. I’m not familiar with the “ARX” brand, but it could be related to a series of prescription safety glasses called ArmouRx.

      Hi Brandy,

      Thanks for submitting your question.

      According to the current ANSI Z87.1-2015 standard, prescription safety eyewear is required to have the following markings.

      1. Manufacturer’s Mark and Z87-2+ on at lease one temple of the frame.
      2. Manufacturer’s Mark and + on the lens (MW+). Additional markings may be included after the + to indicate special lens properties.
      3. Both detachable side shields must be marked Z87+.

      If any of the above markings are missing from the frame or lens, then the eyewear is not in compliance with the current ANSI standard.

      Please let me know if you have any other questions.

    Dear Michael,
    Does “ANSI Z87.1 dustproof and splashproof” correspond to any IP rating for ingress protection, for example IP54?

    • Michael Eldridge April 10, 2017 at 3:42 pm - Reply

      Hi Javor,

      Thanks for submitting your question.

      In my experience, IP rating or International Protection Rating is defined as. Classifies and rates the degree of protection provided against intrusion (body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The equivalent European standard is EN 60529.

      The ANSI Z87.1 dustproof and splashproof markings are unrelated to IP Ratings. If you have another source or if you’re referring to a different “IP Rating” please let me know.

      Hi Polly,

      Thanks for your question.

      Some protective eyewear brands/styles have both ANSI & CE markings. Whether or not a particular style features ANSI or CE markings usually depends on the market its sold in. Products sold in Europe will have CE markings while the same product sold in the USA will feature ANSI markings.

  29. Javor Kolev April 12, 2017 at 4:43 pm - Reply


    Yes, I meant same IP standard, IEC 60529. Sometimes they call it International Protection, sometimes Ingress Protection, and ratings are shown as IPxy where ‘x’ is for solids and ‘y’ for liquids, as in the chart on the link.

    Higher IP rating levels refer to dust and liquid. For example, an IP54 rating means dust-protected and protected against water splashing.

    I wonder – if the “ANSI Z87.1 dustproof and splashproof” qualification does not map to IP54 or another IPxx rating, what is it related to, what does it mean.. Do you know?

    many thanks

      In my experience, the IEC 60529 is not related to protective eyewear and doesn’t translate to ANSI Z87.1-2015. Protective eyewear that is dust or splash rated must have the following marks per ANSI Z87.1-2015.

      D3 = Splash/Droplet
      D4 = Dust
      D5 = Fine Dust

    Hi Michael,

    I’m having a hard time figuring out if photochromic lenses are permissible for OSHA/ANSI regulated safety glasses. Is this something you can clarify for me?


    • Michael Eldridge April 18, 2017 at 3:36 pm - Reply

      Hi Katrina,

      Thanks for submitting your question.

      In Annex K. “Hazard Assessment and Protector Selection” of ANSI Z87.1-2015 the following statement about photochromic eyewear is listed.

      “Photochromic lenses darken when exposed to, and fade when removed from ultraviolet radiation or sunlight. They are frequently used to provide comfortable vision for a wide range of ambient illumination. They should be used with care where the wearer passes from outdoors to indoors in the course of the job. Photochromic lenses that do not meet the transmittance requirements of Table 6 and the switching index requirements of Table 11 are not suitable for protection from direct exposure to high radiance sources (e.g., welding arcs and unshielded high-intensity lamps). Photochromic lenses that do not meet the switching index requirements in Table 11 are not automatic darkening welding filters. Photochromic lenses should be used only after a complete hazard assessment and at the discretion of the person responsible for the selection of protectors“.

      I would add that the variable lens tint itself, however, is separate from and does not affect the ability of the eyewear to satisfy the impact protection testing minimums of Z87.1+. Similarly, the photochromic lens itself will not increase nor decrease any level of protection offered by the integrity or design of the frame and lens. As such, the question of suitability for a given task at hand may lie within the requirements or standards set forth by the manufacturer of any equipment being used, the person(s) responsible for providing protective gear, and/or the lighting environment a wearer is exposed to during his or her work.

      I hope my answer gives you some clarity. Let me know if you have any other questions.

      The L1.3 is referencing Table 9, which refers to Transmittance Requirements for Visible Light Filters. A lens with the L1.3 marking has the highest visible light transmittance range with a maximum VLT of 85%, a nominal of 74.5% and a minimum of 67%. Basically, a clear lens would be closer to 85% VLT while a yellow lens will be closer to 67% VLT.

      This is a difficult question to answer because I’m not aware of a side by side comparison/study for these standards.

If you’re working in Europe, then you should be using safety eyewear that is compliant with EN166.

      The side shields must be marked with Z87+ to be certified. The lenses of your prescription eyewear should also bear the manufacturers mark, followed by a “+” for impact rated lenses.

    I am looking for a ballistic set of glasses that also doubles as a prescription lens. Some in service models have frame inserts and these always seem to get dirty because oil from the eyelashes rub on the lens attracting dirt. The frames restrict field of vision especially on the sides. Even when shooting from the prone position the extra lens makes it difficult to focus. Due to my military role the glasses need to be a wrap around to protect from blood splatter etc. Reading what manufactures have to offer is always fraught with ambiguous language because they out to make a buck.

    therefore, do you have any suggestions as to a suitable set of mil spec ballistic glasses that come with one lens, either normal or prescription, and offer wrap around protection?

    • Michael Eldridge June 21, 2017 at 3:50 pm - Reply

      Hi Stephen,

      Thanks for submitting a question.

      While your desired combination of features presents some challenges, such as a prescription lens in a wrap-around design (generally a conflict in itself), and then a ballistic rating to boot, I believe the best solution here is the Wiley X SG-1.

      These are ballistic rated to the current standard MIL-PRF-32432(GL) and have been worn by the military for many years. In fact, they used to be on the Army’s Authorized Protective Eyewear List (APEL). They are Rx-Ready, in that the removable lens carriers can be easily fitted with prescription lenses (this model does not use an insert). There are two sets of carriers in each kit, giving you the option of having an alternate lens tint.

      The SG-1 is a convertible style, meaning it can switch from a glasses to goggle configuration (includes changeable strap). Because the frame is so flexible, you might consider wearing these as a low profile goggle for an optimum seal, protection, and fit.

      This lightweight unit is also NVG compatible.

      Other “glasses” options include these brands and models:
      – Bobster: Echo
      – Smith: Hideout, Hudson
      – Wiley X: Guard, Romer III, *Echo, *Gravity, Saint, Valor, XL-1 Advanced
      Note: The Wiley X Echo and Gravity are technically not ballistic rated.

      * Specifically stamped Z87-2 for prescription use/compliance

      Please let me know if you have any questions.

          Hi Stephen,

          Thanks for submitting your question.

          For plano safety eyewear the Z87+ marking indicates the style meets “side shield requirements” because the eyewear provides sufficient side protection. However, traditional prescription safety glasses typically need to have side shields attached to the frame to provide the necessary side protection. Some plano, wrap-around safety frames can have Rx inserts installed, which means the standard Z87+ markings apply.

      Hi Serkan,

      Thanks for submitting your question.

      Basically, both statements mean the same thing. Eyewear that “Meets ANSI Z87.1 High Impact Requirements” is ANSI Z87.1+. Even though certain brands/styles of safety eyewear may say it exceeds ANSI Z87.1, I would use caution because you don’t know how much they exceed ANSI standards. For Airsoft applications I would recommend using Ballistic-Rated eye protection with a tight seal around your eyes because the impact velocity is much higher than ANSI uses (around 650 fps vs 150 fps).

      The good news is you don’t have to spend a fortune for ballistic-rated protection. You can find our large selection by clicking here.

      No. The ANSI Z87.1-2015 standard has nothing to do with eclipse viewing. The only safety glasses that are approved for viewing a solar eclipse must have Shade 14 or higher welding lenses. No other lens color is approved for viewing a solar eclipse because the tinting is not dark enough. Viewing a solar eclipse with eyewear containing any lens tint other than Shade 14 will cause severe damage to your eyes.

      No. The Radians safety glasses you purchased several years ago are NOT suitable for solar eclipse viewing. The markings R+S5 means the lenses are made by Radians and lens color is Shade 5 Infrared (welding). You need a Shade 14 or higher lens to safely view a solar eclipse.

      I highly recommend you use Solar Eclipse Eyewear that is ISO 12312-2 certified. You can find more information about certified Solar Eclipse Eyewear at American Paper Optics.

    Mr. Eldridge: This is a most informative site; your Q&A section is especially informative.

    I cannot find glasses that are safe to use for looking at next week’s solar eclipse. I am considering shopping for welder’s glasses.

    My question for you is: what ANSI markings should I look for in glasses that are “eclipse proof”?

    Many thanks.

      Hi Arlen,

      Thanks for submitting your question.

      The ANSI Z87.1-2015 standard has nothing to do with eclipse viewing. With that being said, the only safety glasses that are approved for viewing a solar eclipse must have Shade 14 or higher welding lenses. No other lens color is recommended for viewing a solar eclipse because the tinting is not dark enough. Viewing a solar eclipse with eyewear containing any lens tint other than Shade 14 will cause severe damage to your eyes.

      An example of the proper lens markings would be R+S14. The “R” designates the manufacturer’s mark/brand, the “+” means the eyewear is high-impact rated and the “S14” means the lenses are Shade 14. Safety Glasses with Shade 14 lenses are rare and difficult to find.

    Michael; Great blog. What are the scale ratings range for ANSI Z87.1 for U and IR That is U from 1 to 6? and what is for IR? and W?

    • Jeff January 3, 2018 at 8:48 pm - Reply

      Sorry for the delay, Wil.
      UV: U 2 – 6, where the higher number offers greater UV protection. With polycarbonate lenses, you’ll always see 6.
      IR: R 1.3 – 10, where the higher number offers greater IR protection.
      W: W 1.3 – 14, where the higher number offers greater protection.

    Thank you Michael Eldridge for your quick response to these solar eclipse viewing questions. I too wondered if my husbands arc welding helmet would be enough protection but after reading your previous responses I think NOT. The problem is that I have been searching for over a week for the approved viewing glasses and they are just nowhere to be found, unless you know a better way of obtaining these massively sought after viewing glasses…..I’ll be constructing a long and large pinhole box viewer tomorrow for the Great American Solar Eclipse on Monday.

    Hello Michael Eldridge, Your site is awesome… very informative. We, too, cannot find viewing glasses anywhere, so I am checking in with you because I of what I read at regarding viewing with shade 13. It says in the “Viewing with Protection” section that “Experts suggests that one widely available filter for safe solar viewing is welders glass of sufficiently high number…Many people find the Sun too bright even in a Shade 12 filter, and some find the Sun too dim in a Shade 14 filter — but Shade 13 filters are uncommon and can be hard to find. Unfortunately, my husband’s welding helmet tops out at 13 not the 14 that you strongly recommend. Additionally, my husband says he is more concerned about the integrity of the ‘Made in China’ helmet’s shade indicator. Is there an at-home adaption we can do to our shade 13 helmet to make it work safely? Many thanks, and, as a homeschooling family, we will remember your site. Thank you, Sharon Morris

      Hi Sharon,

      Thank you for submitting your question.

      I advise you don’t modify or augment your husband’s welding helmet in an attempt to make the lens “darker.” You have no way to verify the modification is actually providing enough tinting to prevent the Sun from causing damage to your eyes. Plus, if his helmet uses a variable lens, there is no guarantee the lens is actually at Shade 13. You’re better off finding certified Shade 14 Welding Glasses or ISO certified Solar Eyewear.

      Personally, I’ve looked at the Sun with Shade 14 Welding Glasses and was pleased with the results, so don’t worry about them being too dark. I understand it’s probably too late to find the appropriate welding eyewear now, so I recommend calling your local library, public schools or churches to see if they will have Solar Eyewear available for tomorrow’s event. Our local library is handing out one free pair of paper Solar Glasses to each family that attends their eclipse event.

      Hi Ashley,

      I believe the ANSI Z78.1 is a typo. You need ANSI Z87.1 rated splash goggles, which means the goggles are ventless or have covered vents so liquids can’t penetrate them. You can browse our selection of splash goggles here.

      The Z87.1 markings are to certify the glasses meet the ANSI Z87.1 certification.

      Here’s an example of a lens marking for Weld Shade 14 lenses, which are the minimum lens tint you can use to safely view a solar eclipse. “R+W14.

      Hi Shannon,

      Thank you for posting your question.

      I would recommend your son look into wearing safety glasses with foam padded frames. The foam padding will block dirt and airborne debris from falling into your son’s eyes. Many foam padded safety glasses come with a head strap as well. Make sure whatever style/model you select has anti-fog lenses because the foam padding will reduce the airflow behind the lens and increase the potential for lens fogging.

      When it comes to arc protection, face shields, and protective clothing are usually involved. I recommend you son check into the OSHA Arc Protection Standards.

      Hello, Francesco.

      If you are considering these for military use, you might also consider asking the manufacturer for proof of ballistic certification. This does not mean I don’t believe it. But since you are asking us, I would prefer not to endorse these without knowing for sure. You do not need to send us proof. If you have the proof, that is enough for us.
      The markings seem legitimate, although I would bet the digit after the U is the number 6, where U6 indicates the level of Ultraviolet filtering. The scale is 2 to 6, where 6 offers the highest level of protection from far and near UV. The L2.5 should be the visible Light filter. The scale is 1.3 to 10, where lower numbers provide greater light transmittance. I’m not sure what the AF is.

      Hi, Frank. Safety eyewear that is certified to meet Z87+ specs was tested to withstand a quarter-inch steel BB shot at 150fps. Can some Z87 (and non-ballistic) eyewear hold up to 500fps? Sure, sometimes. But you don’t want to depend on “sometimes”. Ballistic eyewear was tested to withstand up to seven times the force — a heavier projectile at 640-660 fps. To ensure protection, this is what you should be looking for. And for maximum coverage, I suggest a goggle.

The official ANSI standard for prescription eyewear that’s tested to the same Z87.1 safety standards is Z87-2. You may access the Rx area here.

    • Jeff January 30, 2018 at 3:48 pm - Reply

      Not many, but some glasses will actually have a date stamp on the frame. Sometimes you can find a date printed on a box or sticker on the box. While the most current version of Z87 is from 2015, that does not mean you are not protected with eyewear made prior to this. There were very few changes from the 2010 standard to that of 2015. There were significant changes, however, from the 2003 standard to 2010. OSHA just adopted the 2010 standard in 2016, so as long as your eyewear meets that version’s criteria, your are compliant in the workplace. But it’s not just about the numbers. Part of the change in 2010 was in taking a more task-oriented approach, to ask, “is your eyewear appropriate for the task at hand?” If the answer is Yes, and your eyewear was made in 2010 or later, then you’re compliant and safe.

    What is the standard for employees that have to have di-electric safety glasses. No metal frames. Can they have a metal hinge and a metal screw?

    • Jeff February 23, 2018 at 2:53 pm - Reply

      William, the general rule for dielectric eyewear in this industry is that NO metal parts should exist on the eyewear. And that is the case for any eyewear that we designate as dielectric. The million dollar question: is a metal hinge and/or a screw – both very very small – acceptable, or can this also create a hazard? I’m not 100% certain that this has been tested. But I have to think that some manufacturer, or at least a standards organization such as ANSI, would have performed such test. It’s logical for us to believe that dielectric safety eyewear excludes metal parts for a reason and, if given the choice, I would err on the side of caution and assume even the small parts could be a problem if the conditions are right.

    Looking to implement safety glasses in our facilities. We are looking for something comfortable that protects against dust and wont fog up, mostly indoor use.

    We have some employees who will need prescription lenses and some that wont. What can you recommend?

    Also, is it common for the company to buy the frames and have their preferred eye doctor install their prescription? Or do most eye doctors make you purchase the frames from them?

    • Jeff March 9, 2018 at 8:11 pm - Reply

      Hello, E. Anti-fog technologies have improved significantly over the years, but “won’t fog up” is a tall order; nobody can guarantee that yet. I can suggest some that are very very good. Bolle’s Platinum Plus coating is excellent, as is Edge’s Vapor Shield. Other very good anti-fog coatings include Scotchgard by 3M, H2Max by Pyramex, and Max6 by Crews. Glasses or goggles with these coatings should treat you right most of the time.

      Keep in mind that breathability (aka airflow) is still important, even with a coating on the lens. This helps maintain moisture and temperature equilibrium on both sides of the lens, the key to prevent fogging. Thus, it’s ideal for goggles to have foam or another indirect vent when not in hazardous splash environments. There are exceptions though.

      Here is a link to our Extreme Anti-Fog section. This includes dual-pane lenses, fans and other technologies to prevent fogging.

      Below is a list of styles to consider, but is not a complete list of all that will work:
      Bolle TPR, Bolle Baxter, Edge Caraz convertible, and Pyramex Isotope

      It’s important to understand that, even with the best anti-fog coating available, moisture can and likely will still build up in the eyewear eventually. The more energy one exerts, the more they perspire, and the more moisture is trapped in the eyewear, especially sealed goggles. Moisture does not equate to fog, however. Most of the time, this will run off the lens, if it accumulates on the lens at all.

      Regarding prescriptions, I believe the Caraz above is Rx-friendly. It’s not uncommon to have scripts made for your safety glasses. However, there are factors to consider. 1) Base-curve of the lens. The more a lens is curved, the harder it is to make a prescription that works and fits. Labs generally like a curve of 6 or less. Many wrapping style safety glasses are up to an 8 or 9, however. Some can work, some can’t. 2) Prescription strength. The stronger the script, the more difficult it is to make it work, again, especially if the lens is very curved. 3) Safety standard. You’re probably familiar with Z87.1. There is a specific version of this called Z87-2 (dash two vs point one) for prescription safety glasses. You can find safety eyewear with this stamp, but not everywhere. It’s not entirely necessary to have unless your employer or state’s OSHA rep are sticklers for stamps.

      Hope this helps.

    Hi there. Do you know if there are any documents that say if it is ok or not ok to repair a safety frame?

    • Jeff March 9, 2018 at 8:22 pm - Reply

      Interesting question, Scott. It seems that question should come up more than it does. Outside of what we consider “premium”, like Oakley, Wiley X, Smith, etc, frames and safety glasses in general are fairly inexpensive, so we don’t get many “repair” questions that I’m aware of. Replacing seems to be the most common solution.

      To answer though, I have never read or heard of such a document. I think claiming [it’s okay to repair] would create a series of liability issues. Aside from that, could it work in theory? I guess it would depend on the nature of the damage. A broken and repaired (e.g. glued) frame could potentially pose more problems down the road than, say, a broken and repaired temple arm. For one, it will almost certainly no longer be considered ANSI Z87.1 compliant. The fixed area could be a weak point in the frame, causing the lens to detach during severe impact, leaving the wearer exposed and/or causing injury. Ultimately, if at all possible, I would avoid an at-home style repair, and just try to replace your eyewear.

    • Jeff March 9, 2018 at 8:52 pm - Reply

      Hello, Christopher. Yes, the ANSI Z87.1 equivalent for Prescription Safety Glasses is Z87-2. That’s “Z-eighty-seven-dash-two”. This stamp on the frame indicates that the frames have specifically been tested to pass Z87.1 industrial standards with prescription lenses.

      The reason it’s common to see side shields on scripted glasses is because, 1) side protection IS a requirement for safety compliance in an industrial environment, and 2) most people wearing scripted glasses prefer to use what they wear all the time already. The problem is, in many settings, their Rx glasses are not very protective at all. In fact, their side shields are sometimes the most protective part of that combination. Any lens made of glass, CR-39, or other non-polycarbonate materials are at risk of shattering or otherwise breaking. That’s a hazard. Many Rx glasses are simply too small to provide much frontal coverage. Lastly, because most are fairly straight across the face as opposed to wrapping around like a sporty sunglass, there are wide gaps through which debris can enter or strike.

      Please note: many Z87.1 glasses can also accommodate scripts, but may not be stamped Z87-2. That’s okay. The issue comes down to, 1) can your lab make the proper polycarbonate (safety) lens to fit that frame, and 2) is someone going to require the actual Z87-2 stamp? Please go to our Prescription Safety Glasses section to search for something suitable for you.

    I have been looking into some anti-fog goggles for use on a minesite in Northern Canada. We require them to be CSA approved. A site I found has them labelled as certified ANSI Z87.1+. Do you know how well this aligns with CSA approval? Thanks!

    • Jeff March 19, 2018 at 8:11 pm - Reply

      Chet, my apologies for the delay here. CSA Z94.3 and ANSI Z87.1 are very similar. There are specifics laid out for impact resistance, flammability, transmittance, size, resolving power, etc. in both standards. The one most people seem most concerned with is impact resistance. Z87 tests eyewear to 150 ft/sec with a 1/4 inch steel ball. The CSA standard uses the metric system, of course. Its testing velocity for impact is 46.5 m/sec, or 152.56 ft/sec. Similar.

      While not all of our safety eyewear are certified CSA, many are. While our goggles are not filterable by CSA, our safety glasses can be. Sepcifically, our safety glasses that are also convertible (to goggles with strap) can be. I’ve provided a link to a filtered result page:
      My recommendations are Guard Dogs G100, Pyramex I-Force, or Uvex Tirade.

    I find a glasses with ANSI Z87.1, CSA Z94.3, CE standard.
    Is it suitable for using at plasm?

    • Jeff March 20, 2018 at 2:11 pm - Reply

      Neval, those standards you mention are specific to countries and/or regions, and do not necessarily relate to any IR protection. You will want something with a filter specifically meant to block Infrared. Please go here for four pages of IR Shade eyewear: While some will say that a Shade 2 is sufficient, I would recommend at least a Shade 3 lens, and possibly the darker Shade 5 for larger or more intense jobs. The higher the filter number the more IR protection you will have, but visibility also decreases as IR protection increases. The UV protection isn’t really affected either way, as the polycarbonate lenses block 99.9% of UV anyway.

    Can you tell me what rating should be used while grinding with the risk of the grinding wheel breaking.
    I have seen the + symbol and some say High Impact but I am having a hard time finding a rating for this type of job.
    Thanks any help would be helpful

    • Jeff March 19, 2018 at 8:22 pm - Reply


      The plus (+) symbol appearing after Z87 indicates Impact Protection. It used to indicate High Impact protection. “High Impact” is a phrase that used to apply to the ANSI Z87.1 standard until it changed in 2010. There used to be two levels of impact protection: Basic and High. That no longer is the case. Since 2010 (and with the more recent version in 2015), Z87.1 says you either have impact protection or you don’t. The + symbol may also appear after the manufacturer’s mark on a lens or frame without the Z87, and that is also acceptable.

      Regarding your application, I believe the rotational velocity of your grinding wheel can largely dictate the level of protection you’d require. At minimum, you’d want Z87+ eyewear. In my opinion, because of the potential for large projectiles from different angles, you should wear this (primary protection) underneath some kind of face shield (secondary protection).

    I have an employee who just had Lasik eye surgery and is currently wearing Dark glasses that have tinted sides and have this marking on the frames side- FO Z87.1 +CE
    We require ANSI approved safety glasses with side shields affixed. The employee believe these meet the ANSI shatterproof requirements, but I am unclear. His eye Dr. indicates these are temporary throw aways and he only needs them for a brief 2 weeks.I cannot allow the employee on the job site with out the proper safety glasses.
    Can you please advise?

    • Jeff March 19, 2018 at 8:28 pm - Reply

      Linda, the FO is most likely a manufacturer’s mark or abbreviation. A brand beginning with F or FO may confirm this. This can precede the Z87 or + symbol, especially on a lens. The + symbol should be directly tied to the Z87.1 stamp, usually written as Z87+. The CE indicates compliance to European standards, most likely the Low impact standard if “EN 166” is not present anywhere.

      There should be markings someplace on the lens(es) as well similar to those on the side, but Yes, a Z87+ or Z87.1+ stamp should indicate compliance. Almost all safety eyewear uses some form of polycarbonate for its lenses, which is inherently shatter resistant and also offers 99.9% UV protection with any lens color.

    Question: My optometrist has provided me with a set of titanium frames for use in a shop environment where flying debris is common. I am concerned that the lenses are not as large as they need to be. The frames are labelled: “TO Z87-2+”. I notice that the standards list a “D3” category for “splash & droplet”, but not a comparable category for flying debris. Will these frames provide enough protection?

    • Jeff March 23, 2018 at 5:53 pm - Reply

      Thanks for the question, Douglas. There is no clear-cut answer for this. The “TO” is just the manufacturer’s mark that doesn’t have any bearing on the protection. The Z87-2 means that it is Z87+ AND made/tested for prescription lenses.

      Correct, D3 indicates certified splash protection. “Flying debris” is quite generalized, so you or a supervisor should determine if your eyewear provides adequate protection from the type and levels of debris you’re dealing with. The Z87+ indicates that your eyewear can withstand impact from a 1/4 steel ball traveling at 150 feet per second. If you have larger, heavier or sharper debris, or if it is traveling faster than that, you should consider eyewear that is ballistic rated (military specifications, e.g. MCEPS GL-PD 10-12; MIL-PRF-32432; MIL-PRF-31013; MIL-DTL-43511D (goggles)).

      Maybe impact isn’t your biggest concern. Glasses come in all shapes and sizes. If the debris you refer to is flying from all directions, it may not matter how large the lenses are. It might be more important to have a closer-fitting wrap-around style that leaves less room for debris to sneak into. Prescription eyewear makes this more challenging, however. Most tight wrapping glasses cannot accommodate Rx without a specific Rx insert. This is where a goggle may be more appropriate. Feel free to respond to this with more info such as what the biggest debris concern is (impact, type, size, direction, all of the above), and perhaps which direction you want to take a solution for this, I can suggest glasses or goggles that may suit you.

    What is the maximum lens shade that can be used for indoor work?

    • Jeff March 29, 2018 at 8:22 pm - Reply

      Mark, I assume you mean the maximum density or the darkest tint. Many years ago, this answer was more black-n-white, so to speak. Since ANSI changed directions on their approach to eye protection in 2010, others, including OSHA, followed suit. So much of it is now, “what is appropriate for the task at hand?”. Per OSHA’s latest Final Rule in 2016, they adopted the 2010 version of Z87.1. There is also the 2015 version; not much different. I find no points or clauses in the 2010 Z87 standard or in OSHA’s Final Rule that puts limits on indoor lens tints. Clear has to be at least 85%. A Special lens tint (S – which is basically anything other than Clear or a Welding lens) shall be between 8% and 85%. There are documents from the 80’s and 90’s where OSHA ruled that tints were acceptable indoors (especially Rose #2 or lighter) when it didn’t create or worsen a safety hazard. Light Blue lenses later became popular to counter the yellow sodium vapor lighting, and Indoor/Outdoor lenses have been popular now for about 15 years. It often comes down to whatever limit(s) your employer imposes as they look to minimize safety hazards. Just hope that they are educated on the subject.

      Farikha, I’m guessing that you are already wearing prescription eyeglasses. I that case, you are probably interested in knowing which glasses you can wear over these. Please see our selection of over-prescription safety glasses here: For polarized sunglasses, you may look here, although they are not certified for safety: To minimize optical distortion, you might consider lenses that are flatter (less curved), such as the Pyramex OTS, Elvex OVR-Spec II, or any of the Guardian models. If bright lights bother you, you could consider an indoor/outdoor tint to dim your view to a comfortable level. Then of course there are darker tints for sunglass purposes.

    Hi there, there are some Elvex Denali lenses that have AF on their marking, for example Z87+ U6 L2.5 AF, what does it mean?

    • Jeff April 12, 2018 at 2:02 pm - Reply

      Andres, My guess would be that it’s indicating an anti-fog coating, although I can’t recall ever seeing that stamped like that. The L2.5 (Visible Light Filter) makes me think your lens is Amber (yellow), but I don’t think the Denali Amber lens is available with an anti-fog coating. It could be the Clear anti-fog, but then I’d expect the L number to be lower, between 1.5 and 2. If you need a firm answer, you might consider emailing them:

    I use a cheap Checklite pair of safety glasses at work. They are marked ‘Z94.3 Z87+ CL150mm.’ Do any of these specs suggest a magnification level? I want unmagnified glasses. Do all safety glasses have some kind of magnification level? Where do I start in getting a pair of unmagnified glasses. If a particular pair of glasses doesn’t mention a magnification level, is it safe to assume there is no magnification in the lense?


    • Jeff April 25, 2018 at 5:08 pm - Reply

      Luke, there is no magnification on the Crews Checklite safety glasses. Most of the markings are related to the Canadian (CSA Z94.3) safety standard and the ANSI (Z87+) safety standards. The 150mm is possibly the temple length, which might be about 5.9 inches. Regarding your last question, yes, generally it’s safe to assume there is no mag if it’s not mentioned, at least on the package. Most safety rated glasses with mag are bifocals, but there are a few – only a few – full lens mag safety glasses.

      Some people are more sensitive to eyewear than others, especially if they’re not used to wearing them. And those people might be particularly sensitive to curved or wrapping lenses. The wrapping offers both style and side protection. Many actually prefer a more traditional or old school look and fit, which features a much flatter lens, plus side shields. The flatter lenses here might suit your eyes better…
      Crews RT2:
      Pyramex Emerge: (Be careful here – there ARE Full Mag options in here, but also regular).

If you’re a manufacturer, use the same markings you normally would. If you’re not, you need not be concerned with how to.

    The Blog indicates Z87 is basic impact, but later you indicate the Z87 marking on a pair of safety glasses meetings Z87.1. My safety glasses supplier indicates Z87 is basic and not high impact, and does not meet Z87.1, but Z87+ does.

    • Jeff May 25, 2018 at 2:43 pm - Reply

      Mike, there is still a lot of confusion since the 2010 revision about basic, high and no impact. I will use an answer (3/19/18) from the same post to clarify. It also appears the post itself may need some updating.

      Let me first clarify that Z87 and Z87+ are slight abbreviations of, but also separate distinctions within the overall Z87.1 standard. The “.1” does not, by itself, mean impact protection, and is not necessarily synonymous with Z87+. It is the formal nomenclature for the parent standard for industrial eye protection.

      The plus (+) symbol appearing after Z87 indicates Impact Protection. It used to indicate High Impact protection. “High Impact” is a phrase that used to apply to the 2003 ANSI Z87.1 standard until it changed in 2010, as there used to be two levels of impact protection: Basic and High. That no longer is the case. Since 2010 (and with the more recent version in 2015), Z87.1 says you either have impact protection or you don’t. The + symbol may also appear after the manufacturer’s mark on a lens without the Z87, and that is also acceptable, providing the full Z87+ is marked someplace on the frame.

      If your safety supplier is speaking in terms of Basic and High Impact, he/she is referring to the 2003 standard. In 2016 OSHA adopted the 2010 version as the official standard.

    Mr. Eldridge,

    Not the right forum for this, but I see you answer the questions here…

    I asked a rep from your company if the glasses I intend to order will come with Z87+ high impact lenses. She replied yes, the frames are rated Z87. I asked her to again read my question, and she replied, yes, the lenses are Z87 rated. I asked her to read my question a third time, but I have yet to get an answer. I work in an environment with a lot of flying debris. I currently wear Z87+ Rx glasses, but my prescription has changed, so I need new. Your optician doesn’t appear to understand what you have outlined in this blog post. Would you let me know if the Rx lenses I am looking to order are Z87+ rated? I need the extra protection. If they are only Z87 rated, honestly, the same can be purchased for much less on other websites, but I would pay the extra if the lenses are higher quality.

    Thank you for your time.

    • Jeff May 25, 2018 at 6:35 pm - Reply

      Tim, I apologize if you feel your question was not sufficiently answered. I was unable to location your conversation in our central communication archives or in our order management system, so perhaps it was an email directly to her. To clarify, we do not have an optician on staff, but our service reps are very knowledgeable. It’s also possible that you contacted somebody at SportRx, whom we work with for our Prescription Safety Glasses. Now onto your question.

      I did not see you specify in your question which glasses you are looking at, but that isn’t critical information, as ALL “safety” eyewear that we stock and offer on our website meets the Z87+ standard for Impact Protection. While some of our “sunglasses” are not certified Z87+, they are also not referred to as safety glasses. So again, all of our safety eyewear — glasses and goggles — meet Z87+.

      It is not clear from the information provided, if you plan to purchase a specific pair from our website and have your own Rx lenses made and installed elsewhere, or if you are planning to have us do them through SportRx. If you are simply purchasing glasses and then having Rx lenses made on your end, then I am left somewhat confused by the concern over Z87+ lenses that would presumably be discarded. If, however, what you’re meaning by “lenses that come with” refers to the custom prescription lenses that will be made and installed in the frame you choose, then yes, those will be Z87+.

      I know that Z87 (non-impact) eyewear exists, but I have yet to see them, and wouldn’t even know where to find them. We work in the safety industry, where nearly everything is in terms of impact protection, or Z87+.

      It should be noted that frames which are specifically designed for and safety tested with prescription lenses are certified with the mark of Z87-2. You might look for those as well.

    Hello I am currently going to welding school and was wondering what kind of safety glasses would be best to use underneath my helmet and for general use. I have been looking at safety glasses that have a strap because I find that more comfortable as well as ones that have a protective shade and dust protection. I guess my main question is what kind of lens color would be best to use, I have been looking at glasses with amber, grey, SCT-Low Ir, and shade 2. Thank you

    • Jeff June 8, 2018 at 4:05 pm - Reply

      Greg, if your helmet has an appropriate filter for your welding tasks, you should not require any additional lens tint. However, some people still prefer something, and that’s fine, as long as you can still see your work sufficiently. Personally, I would think gray or shade 2 would be too dark under a welding filter/screen. If you prefer eyewear with a strap that you should check out our Convertible Safety Glasses section. These include strap and temples for use a goggle or glasses configuration. If any dust or debris is sneaking in behind your helmet, this is a good solution. My personal favorites in this group are Edge Caraz, Elvex Go-Specs II, and Guard Dogs G100.

    • Jeff June 25, 2018 at 4:10 pm - Reply

      Len, these markings are standard. The Z87+ simply indicates the glasses are rated for impact protection per ANSI Z87.1 criteria. The “8” would likely be an indicator of the level of visible light filter. The scale ranges from 1.3 to 10, with the higher numbers, such as 8, blocking more light. You probably have a gray, brown or mirror lens in the 10-18% VLT range. This is normal.

    Once a product is certified to ANSI Z87.1-2010 how long is the certification good for? In other words, does the manufacturer have to submit items for testing annually to keep the certification or is once enough?

    • Jeff July 12, 2018 at 3:16 pm - Reply

      Excellent question, Judd. The certified glasses remain compliant as long as, 1) the design and manufacturing process of the glasses has not changed, and 2) The Z87 standard has not changed. Some consider OSHA the authority on general industrial safety. Most people don’t realize, however that OSHA is usually at least one standard behind. I can’t speak on all other safety standards, but regarding Z87.1, OSHA just adopted the 2010 standard in March of 2016, about a full year after the 2015 version was released by ANSI-ISEA. To their credit, OSHA and others realize that it takes time for industries, manufacturers, etc. to catch up.

      When the Z87 standard made its significant changes in 2010, that didn’t suddenly mean that eyewear certified based on the 2003 version was non-compliant. It was more about changing the approach to safety and how we view eyewear and the hazards associated with them. The bulk of the testing didn’t change, so what protected us in 2009 still protected us in 2010, and was still acceptable. That is true of eyewear today as well.

    Hello Michael,
    I’m trying to locate in ANSI, or elsewhere, stipulations on which visible light transmitted levels (VLT) of tinting, if any at all, is allowed for safety glass use indoors. I see where some manufacturers recommend indoor use for specific safetey glasses which might have: light amber lenses, rose colored lenses (even an OSHA letter of interpretation here) and even some light blue lenses but I can’t find anything specific in the Z87.1 package I downloaded from ANSI covering years 1989, 2003 & 2010. I need to be able to tell our workers which glasses they can and cannot use while working construction indoors. Is there a VLT threshold level? Nothing under 80%, for example? Does it matter which tasks are being performed? (i.e., Inspection, supervision, power tool use). Any guidance from anyone would be greatly appreciated. Thanks in advance.

    • Jeff July 12, 2018 at 4:20 pm - Reply

      Richard, if you can find where that is officially written, you’ve discovered the safety eyewear holy grail. Such a limit is far more likely to come from OSHA than ANSI. I thought I’d read something like what you describe years ago, but I cannot find it now. The lenses permitted in a facility can be up to the employer, and some will try to limit it to Clear lenses. However, most will accept — I think OSHA does/would as well — those you listed: light amber or yellow, a rose/pink #2 or lighter, and light blue. I think 70% light transmission or higher is a reasonable guideline, assuming sufficient lighting already exists. You might find the occasional rose or blue that dips slightly below that at 68 or 69%, and I would let that slide as well.

      Given that many companies allow Indoor/Outdoor (50-60%) lenses, it’s evidence that businesses are coming around to the idea of flexibility and ideal tints for given conditions. The typical I/O lens has a light mirror coating on the outside, however, and some businesses won’t permit any mirrored lens. In excessively bright conditions, it’s not uncommon to see the medium roses, blues and light bronzes come out, and these may fall in the 50-65% range.

      I would worry less about lenses being task-specific, and more about being light-condition-appropriate. Ultimately, we want the clearest view possible whatever we’re doing, so that may mean reducing the glare and blinding brightness, and enhancing contrast. That said, rose/pink/vermillion is the best for most inspection applications, while the blue lens will offer the least benefit in terms of contrast and clarity. Blue is most beneficial in neutralizing yellow sodium lights.

      Our website does offer the ability to filter by lens color. For the largest list, simply click here, then use the lens color filter to the left of the page. Good luck.

    I was recently out in the field performing a safety audit on a group of welders. The inside of his welding shield had a sticker with some general information, and on one line said that it was not rated for impacts from grinders. The crew then proceeded to say they use these all the time as they are ANSI certified. I guess my question would be, if they are rated for impact why does this sticker say they are not?

    • Jeff July 12, 2018 at 4:47 pm - Reply

      Thanks for your question, Kevin. First, if they insist the shields are ANSI certified — I presume they mean Z87.1 — you should be able to find a stamp or two on the shield to confirm this. If not, I question that claim. You should also be able to look up the make/model online for more information if you’re not sure. Regarding the grinder question, it’s possible that the maker of the shield believes it’s possible for a grinder to launch a projectile at a velocity great than 150 ft/sec., which is the testing speed for the high velocity impact test of the Z87 standard. That is of particular concern if the projectile is also of greater mass than 1/4 inch BB at 1 gram. This means more total force impacting the shield, which invites liability. Granted, that explanation for their sticker is purely speculation. I would suggest contacting the manufacturer of the shield to get their true take on it.

      It is important to note that proper wearing of welding hoods/masks/shields includes the use of primary eye protection underneath which itself should be Z87+ rated.

      Robert, I’m not sure what make or model your safety glasses are, but chances are the lenses are polycarbonate, as is usually the case. Polycarbonate blocks 99.9% UV light naturally, so you’re in pretty good shape. I would just try to verify the lens material, but it’s highly unlikely it’s anything other than that.

      Nora, there are a few things to consider here. 1) Note that ALL eyewear label “safety” (glasses or goggles) on our website is Z87+ certified. 2) There are varying degrees of side protection and many styles have built-in sideshields, more or less. 3) Some styles come with a cord, but most do not, and even fewer with the sideshield style you’re looking for. 4) We offer a wide variety of separate cords.
      Onto the glasses with shields… Nuvo; Ranger Mini OTG (can barely call this one an OTG, but has great side pro); Traditional (popular, oddly enough, but the shields are a tight mesh vs solid); Swagger (a tad bigger/heavier, but solid); RT2.
      Cords… Choose from this variety. Note the clip-on style only works if your temple arm tips have the holes to lock into.

The Shade 3 lens allows approx 12% VLT (visible light transmission), while the Shade 5, which is much darker, is estimated around 2% VLT. The Shade 3 blocks 95% of Infra Red light from 780-2000nm and the Shade 5 blocks 99% at the same wavelength. Here’s a link to a list of our safety glasses for InfraRed protection.

    I teach high school chemistry and normally order the NSTA recommended Z87+D3 goggles. I have received a box of Z87.1+ goggles to pass out to students.
    Can you tell me if these still meet the standards for working in a chemical lab?
    Thank you so much for your help!

      Thank you for your question, Jamie.

      If the goggle lenses are marked with “D3” or “Z87+D3”, they meet the standard for splash and droplet protection. However, if they’re an older model, they may not have the updated markings. If you can provide me with the brand and model names, I should be able to confirm their compliance.

      Non-vented or indirect vented goggles are recommended for liquid splash protection. If you received perforated or direct vent goggles, then I would suggest you don’t use them around liquid splash hazards.

    I usually purchase a goggle that is Z87+D3 for my chemistry students. Somehow a different brand was ordered from Amazon that is Z87.1+
    The goggle brand is Gateway Safety 32392 Traditional Technician Splash Safety Goggle, 390 Cap Vent, Clear Anti-Fog Lens.
    I don’t know if I should return them or if they meet the same standards.
    Thank you for your help!

    Are there requirements or recommendations on marking product/boxes when the glasses are NOT ANSI Z87+ approved?

      Thank you for your question, Julie. I’m not aware of any requirements that state eyewear must be marked to show they are NOT ANSI Z87+ approved. You should only use eyewear that clearly displays the appropriate ANSI markings.

    Can you please tell me if goggles that comply with ANSI Z87.1-2003+ are the same as Z87+D3? My concern is whether they offer chemical splash protection in a chemistry lab.
    Thank you for your help.

      Thank you for your question, Jamie.

      The D3 marking is used to indicate compliance for liquid splash and droplet protection. Older ANSI Z87.1-2003 marked goggles may not have the D3 markings because the marking requirement didn’t exist when the goggles were manufactured. However, safety goggles with indirect venting (covered-vents) or ventless construction are safe for chemistry lab use. You want to stay away from perforated goggles because they don’t offer enough protection from liquid splash hazards.

    Hi Michael,

    For how long the ANSI Z87+ Test Lab Reports are valid? One year’ or it never expires?

    Thank you.

      Thank you for your question, Christopher.

      The ANSI testing is valid for the life of the eyewear model. However, when new ANSI standards are announced the manufacturer may have to submit the eyewear model for retesting to ensure they meet the new standard.
