Hazed and Confused: The Value of Anti-Fog Technology on Safety Glasses

The reason workers, specifically those at-risk for suffering an eye injury, stop wearing required safety glasses may seem, well, a bit foggy.

Safety glasses that fog up—or more precisely, glasses exposed to condensation due to humidity or a rapid change in air temperature—can frustrate workers who are required to wear protective eyewear on the job.

Occupational Health and Safety (OHS) data cited in a 2009 study in Accident Analysis and Prevention Magazine indicates that construction, manufacturing, service and retail workers often refuse to wear their safety eyewear because of fogging.

Environmental factors that contribute to fogging include:

  • Level of ambient heat in the work environment

  • Increases or changes in humidity and moisture in the air

  • Lack of air flow caused by tight-fitting eyewear

Even in cold weather, the temperature variance between a worker’s heated, sweating body and the frigid outdoor air can produce the condensation that causes fogging. To avoid having to deal with this, workers may remove their safety eyewear to wipe them dry, or even worse, stop wearing them entirely to avoid obscured vision. Now there’s a risk of injury for two reasons – non-compliance and fogging.

But There Is Good News

Safety eyewear that incorporates anti-fog technology can significantly decrease eye injuries by reducing or eliminating fog/condensation and providing the worker with a consistently clear view. This increases compliance and eliminates the need to constantly remove and wipe the glasses, boosting both safety and productivity. With the anti-fog technology available today, fogging should become a thing of the past for workers in these tough work environments.

Not All Anti-Fog Technologies Are Created Equal

Still, not all anti-fog technologies are created equal. Many safety glasses feature anti-fog coatings that are a topical treatment to the lens’ surface. However, such coatings can have a limited life span, with the potential to wash off after only brief time worn. Anti-fog treatments are most effective when they are permanently bonded (i.e., inherent) to the lens. An example is Ergodyne’s Skullerz Anti-Fog Technology that will not wash or wear off after long-term use, even in extreme temperatures. Understanding how the anti-fog technology is applied is critical to properly evaluating and making purchasing decisions on anti-fog eyewear.

Choosing The Best Anti-Fog Safety Glasses

Wearing anti-fog eyewear where changing temperatures and humidity are a daily reality can help improve worker safety and workplace compliance. It’s an effective way to reduce fog and promote good vision. When selecting eyewear making anti-fog claims, look for technologies that are permanently bonded to the lens for the best anti-fog performance that won't wash or wear off.
