How to tell if my glasses are polycarbonate or not?
-
What are the characteristics of polycarbonate lenses? I mean, are they clearer or something than plastic lenses? Are most glasses made of polycarbonate?

Answer:
Polycarbonate is a plastic. Anyways, different materials have different refractive indices, the higher the refractive index, the less curvature is needed for the same lens hence the glasses can be thinner.
