A method for increasing the extinction coefficient of a copolymer of ultraviolet radiation at 370 nm through an intraocular lens comprising: (a) incorporating a monomer comprising a 4-(4,6-diphenyl-1,3,5-triazin-2-yl)-3-hydroxyphenoxy moiety into at least one polymer and (b) forming the polymer into a material suitable for use as an intraocular lens, wherein the monomer comprising a 4-(4,6-diphenyl-1,3,5-triazin-2-yl)-3-hydroxyphenoxy moiety - is represented by formula: wherein -- L is a C 1 to C 5 alkyl substituted by one, two, three or four halogen, amine, trifluoromethyl, (C 1 to C 5) alkoxy, or (C 1 to C 5) straight or branched alkyl optionally substituted by one, two, three or four hydroxy, halogen, amine, (C 1 to C 5) alkoxy or trifluoromethyl; -- A is an acrylate, methacrylate, acrylamide or methacrylamide and L is covalently bound to A by the oxygen or nitrogen atom of A, and - is present in 0.10 to 0.15 weight percent of the overall dry polymer; wherein the transmittance of ultraviolet radiation at 370 nm in an optic portion of the intraocular lens with a hydrated thickness of 300 microns to 1000microns is ten percent or less, and wherein the amount of the monomer of formula does not substantially affect a physical characteristic of the lens other than transmittance of ultraviolet radiation.
