Method for polymerizing contact lenses having UV absorbing properties |
摘要 |
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; exposing the monomer mixture in the mold to a light source including ultraviolet light to cure the monomer mixture and form the lens, whereby the non-UV-absorbing compound converts to a UV-absorbing agent.
