Sunglasses consist of a pair of light-filtering lenses and a frame to hold them in place.
The vast majority of lenses are made of colorized plastic, such as polycarbonate.
What material are sunglasses made of?
Sunglass lenses are made of either glass, plastic, or SR-91. Plastic lenses are typically made from acrylic, polycarbonate, CR-39 or polyurethane. Glass lenses have the best optical clarity and scratch resistance, but are heavier than plastic lenses.
What are sunglasses frames made of?
Most plastic glasses are made of zyl (also called zylonite, acetate and cellulose acetate) or propionate. Other materials used in plastic frames include polyamide, nylon, polycarbonate, carbon and Optyl (a brand of epoxy resin).

Are plastic eyeglass frames better than metal?
Metal frames. Metal frames have a very minimalist look and are generally a lot thinner and more lightweight than the plastic glasses frames. Unlike plastic frames, metal frames come with the option to go semi-rimless, where the lenses are not fitted inside a metal frame, but simply attached to the arms.
