KleenGuard Nemesis Safety Glasses feature clear anti-fog lenses for outdoor use, especially while moving between hot, cold and humid areas. KleenGuard Personal Protective Equipment enables rather than inhibits to allow maximum productivity and safety for you and your employees. Anti-fog polycarbonate lenses provide 99.9 percent UVA/UVB/UVC protection to help prevent eye damage like cataracts, retinal damage and other conditions that can cause temporary vision loss. Wraparound frame has a base curve of 8 that extends the range of peripheral protection as well as soft-touch temples for comfort. Lightweight safety glasses have a patented nosepiece designed to be extremely flexible, to channel sweat away from the eyes and to help prevent slippage down the nose. Each pair of safety glasses comes with a neck cord so that the glasses are ready to protect at a moment's notice. Safety eyewear is manufactured to comply with the ANSI/ISEA Z87.1+ standard for personal eye protection.
