METHOD FOR POLYMERIZING CONTACT LENSES |
摘要 |
A method for photopolymerizing a monomer mixture to form a lens involves charging to a mold a monomer mixture including lens-forming monomers, and exposing the monomer mixture in the mold to a light source including light in the visible region of the spectrum. The method is useful for monomer mixtures that include a UV-absorbing compound and/or a tinting agent. Preferably, the monomer mixtures include a polymerization initiator including a phosphine oxide moiety.
