From construction workers to first responders to welders, dealing with fogged eyewear is incredibly frustrating. And, lens fogging is proven to be a significant safety issue. Anyone working outside in warm weather can struggle with fogging eyewear.

Fortunately, several solutions exist for this problem. However, before we get to those, let’s first understand the problem by looking at the leading causes of fogging eyewear.

Why do lenses fog?

We’ve all seen a glass of cold water sweating in the sun. This “sweating” occurs because there is a temperature difference between the inner and outer surface of the glass. Your fogged eyewear is a result of the same process. There is a temperature difference between the inner and outer surface of the lens; therefore, your lenses begin to “sweat”. 

The key factors contributing to fogging include:

  1. Ambient heat: This is the temperature of the surrounding environment. 
  2. Tight eyewear: Overly snug eyewear causes a lack of air flow. This problem is commonly associated with goggles and wraparound lenses.
  3. Increased humidity: The more moisture in the air the greater the chances for lens fogging. High levels of humidity are why lens fogging problems increase on hot and humid days.
  4. Human exertion: Working hard causes your body to heat up and produce sweat, consequently, the added heat and moisture contribute to lens fogging.

Safety Issues Caused by Fogged Eyewear

Anyone with an eye for safety realizes the significant issues caused by fogged eyewear. These safety issues fall into three three main categories.

  1. Non-Compliance: Unfortunately, a solution for many is to remove their safety eyewear, making them vulnerable to a host of eye injuries.
  2. Impaired Vision: Fogged eyewear impairs a workers ability to see clearly, which leads to an increased possibility of harm.
  3. Constant Lens Cleaning: Workers are always removing their safety eyewear to wipe their lenses, which exposes them to potential eye injuries.

Independent research, as reported in OH&S, confirmed:

fogging is the number one vision-related barrier to wearing safety glasses. 

And, 28% of safety professionals believed fogged eyewear had contributed to injuries in their workplaces.

5 Solutions for Fogging Eyewear in Hot Weather

While no product provides 100% fog-proof protection, solutions do exist that significantly reduce or delay lens fogging. Therefore, consider the following five suggestions for eliminating fogged eyewear both as a safety hazard and annoyance.

  1. Start simple. Often, just a simple change in eyewear design makes all the difference. A style that allows more air to flow around the lens will reduce or delay fogging.
  2. Apply anti-fog coating. In many cases, employers report the almost 100% elimination of problems caused by fogging eyewear after workers apply an anti-fog coating to their safety eyewear. Knowing How to Use Anti-Fog Solutions is the key to eliminating fogged-up eyewear.
  3. Buy Anti-Fog Eyewear. Almost uncountable options exist when it comes to finding the right anti-fog safety eyewear. Anti-Fog lenses are available in nearly any lens tint or style. You can even find them in bifocal and polarized versions.
  4. Go extreme. For most, glasses with anti-fog coating are enough to solve the problem, but a few others (for example, those needing to wear both prescription eyewear and safety eyewear or those working in extreme heat) need a more radical solution. So, they turn to Extreme Anti-Fog Goggles because of their dual-pane lenses that eliminate condensation and their built-in fans that forcefully remove moisture and reduce fogging.
  5. Use a neck strap. Non-compliance often comes when workers remove glasses because of fog and fail to put them back on. Wearing a neck strap or retainer keeps your safety glasses nearby, hence, increasing safety compliance.

In Conclusion

Don’t fall victim to fogging, which is one of the biggest frustrations, and reasons for non-compliance regarding safety eyewear. Consider the cause of your particular fogging problem, and take the necessary steps to eliminate it.
