What’s New? An Update on the State of Anti-Fog Eye and Face Protection, Technologies and Best Practices
Overview: Fog limits the effectiveness of Personal Protective Equipment (PPE) for eye and face protection. According to the American National Standards Institute (ANSI), it is one of the three most significant barriers to their use, ahead of lack of comfort and fit and scratching. If lenses are fogged, people won’t wear them. If workers can’t see, they could have accidents.
Fog forms on a surface when water vapor in air condenses in fine droplets. A good anti-fog (AF) coating should prevent the formation of such droplets, but not all AF coatings are the same. Typical AF products perform well right out of the package. But after use and cleaning, the coatings will lose effectiveness and come off over time.
