UV/visible light absorbers for ophthalmic lens materials

1. An intraocular or contact lens comprising an ophthalmic device material formed by copolymerizing a composition comprising i) a device-forming monomer selected from the group consisting of acrylic monomers and silicone-containing monomers, and ii) a benzotriazole compound of the formula

wherein

R 1 =H, CH 3 , CH 2 CH 3 , or CH 2 OH;

R 2 =C 1 -C 4 alkyl; and

R 3 =H, CH 3 , CH 3 O, F, Cl, Br, I, or CF 3 .

2. The lens of claim 1 wherein

R 1 =H or CH 3 ;

R 2 =C 1 -C 4 alkyl; and

R 3 =H, CH 3 , CH 3 O, F, Cl, or CF 3 .

3. The lens of claim 1 wherein the benzotriazole compound is 2-hydroxy-5-methyl-3-(5-(trifluoromethyl)-2H-benzo[d][1,2,3]triazol-2-yl)benzyl methacrylate.

4. The lens of claim 1 wherein the ophthalmic device material comprises from 0.1 to 3% w/w of the benzotriazole compound.

5. The lens of claim 4 wherein the ophthalmic device material comprises from 0.2 to 2.5% w/w of the benzotriazole compound.

6. The lens of claim 5 wherein the ophthalmic device material comprises from 0.3 to 2% w/w of the benzotriazole compound.
