ABSTRACT:
A method for preparing a lens having UV-absorbing properties involves charging to a mold a monomer mixture comprising lens-forming monomers and an essentially non-UV-absorbing compound, and curing the monomer mixture to form a lens, followed by treating the lens to convert the essentially non-UV-absorbing compound to a UV-absorbing agent.
