Polycarbonate

Polycarbonate plastic lenses are the best bet for individuals who will be movin’ and shakin’ in their sunglasses. Polycarbonate lenses are made from a similar material to that of aircraft windshields and are virtually indestructible. Polycarbonate is light and scratch resistant (not scratch proof), offers a high level of optical clarity, and is 50 times more impact resistant than optical glass making for a very strong, distortion free lens. The only disadvantages are a slightly lower level of scratch resistance and optical clarity that’s not quite as good as optical glass or NXT.
