Method for polymerizing lenses

摘要

A method for photopolymerizing a monomer mixture to form a lens involves photopolymerizing a mixture of lens-forming monomers that includes an initiator of the formula:wherein:Ar represents an aromatic radical;R<a >represents a secondary amino radical;R<b >represents an ethylenically unsaturated radical or an aromatic radical; andR<c >represents a secondary amino radical.
