Abstract

Opthalmic devices, particularity intraocular lenses (IOL), with improved contrast sensitivity and methods of making same. In one aspect, blue light blocking chromophores (BLBC) are diffused into, e.g. an IOL lens body to create a BLBC gradient in the lens. Orange dyes are preferred BLBCs.

Claims6

Dependent claims

An intraocular lens consisting essentially of a copolymer of an ophthalmic device base monomer and a polymerizable orange dye.

Dependencies are inferred from the claim text.
