Glass

Optical quality glass lenses provide the clearest vision because they are ground and polished like a fine camera lens, so the surface of the lenses are free of any imperfections. Optical-quality glass sunglass lenses are chemically or heat treated to make them impact-resistant. While glass is heavier than plastic, it keeps its shape when heat is applied. This means that glass lenses will do better than plastic if accidentally left on a dashboard in hot afternoon sun. Glass is more scratch-resistant than plastic.

CR-39

Optical quality plastic, made of hard resin, is considered the best and most common plastic used for sunglass lenses. It weighs half as much as glass, which means it is not heavy on the face. It exceeds requirements for impact-resistance because of its molecular structure.

Polycarbonate

Compared to CR-39 and glass, polycarbonate plastic weighs the least and is the most impact-resistant. Polycarbonate is a great choice for those individuals who want really rugged sunglasses, including people who engage in outdoor activities and fast-action sports. Polycarbonate is widely used, and is considered the second most common optical plastic. One drawback is an increased susceptibility to scratching and abrasion, but with a hard-coat applied its scratch-resistance is similar to that of CR-39.
