ABSTRACT:
A cemented lens consists of a lens that is tinted and/or contains a UV absorber, and a second lens that is neither tinted nor contains any UV absorber. The cemented lens is formed by placing the two lens elements together with a UV-curable adhesive between them, and then directing UV radiation through the first lens to cure the adhesive.
