Patent ID: 8236053

Claim:
A polymeric ophthalmic device material formed by polymerizing a composition comprising a) 0.1 to 5% (w/w) of a UV absorber of formula (I): wherein in formula (I): R is H, C 1 -C 4 alkyl, —C(═O)C(═CH 2 )X, or —C(═O)O—(CH 2 ) n O—C(═O)C(═CH 2 )X; n is 1-6; X is H, CH 3 , or CH 2 CH 3 ; Y 1 , Y 2 independently are H, Br, Cl, F, I, OCH 3 , NO 2 , —C(═O)C(═CH 2 )X, or —C(═O)O—(CH 2 ) n O—C(═O)C(═CH 2 )X; and Y 3 is H, Br, Cl, F, I, OCH 3 , or NO 2 ; provided that no more than one of R, Y 1 , and Y 2 may be —C(═O)C(═CH 2 )X or —C(═O)O—(CH 2 ) n O—C(═O)C(═CH 2 )X; and b) a device-forming monomer selected from the group consisting of acrylic monomers and silicone-containing monomers.
