The invention is a polymeric ophthalmic lens material comprising a polymeric ophthalmic lens material comprising a) one or more lens-forming polymerizable monomers selected from the group of hydrophilic acrylate-substitute monomers, hydrophobic acrylate-substituted monomers, vinyl-substituted monomers, and platinum-catalyzed vinyl hydride addition-cured silicones, b) a polymerizable ultraviolet absorber and c) a polymerizable yellow dye. In one embodiment of the invention, the polymerizable ultraviolet absorber has the formula: n nand the polymerizable yellow dye has the formula:n n nwherein R 1 =vinyl, R 2 , R 3 =H, alkyl, hydroxyalkyl, wherein R 2 =vinyl, R 1 , R 3 =H, alkyl, hydroxyalkyl, and wherein R 3 =vinyl, R 1 , R 2 =H, alkyl, hydroxyalkyl. |
