Question: are crizal lenses glass or plastic?
Answer: Crizal coated lenses are as “breakable” as the material the Crizal coating is applied to. Currently there are no ophthalmic quality lenses that are considered completely unbreakable. Lenses made of standard ophthalmic plastic (CR-39) are far less breakable than glass, but more breakable than polycarbonate or Trivex.
