100% Uv Coating

Ultraviolet radiation ("UV") has been determined to cause eye problems when the eye exposed to the sun for too long.  Regular plastic CR39 lenses need to have UV coating applied to reduce the risk of eye damage.  However, polycarbonate, High index, and Trivex lens materials all contain UV protection inherent in the material.  Also, regular sunglasses have UV protection (by law in the U.S.), and polarized sunglasses, and Transitions lenses all include UV protection inherent in the lens.
