Sturdy, 500 Series goggles have a low-profile design with an adjustable strap and indirect ventilation. Anti-fog coating allows workers to enjoy reliable, clearer sight longer, because the coating with its active ingredient is bonded to the lens. Anti-fog coating helps keep lenses clear in, steamy and wet environments. The coating retains its effectiveness for at least 25 washings with water and withstands disinfection with diluted bleach soaking or alcohol wipes without losing its anti-fog performance. The anti-fog coating produces a reduced-contact angle, flattening the water beads into a thin, transparent film of water that allows light to pass through. Offers excellent protection against UV radiation. Optical class 1 lens suitable for prolonged use.
