RADIATION-ABSORBING POLYMERIC MATERIALS AND OPHTHALMIC DEVICES COMPRISING SAME

摘要

A radiation-absorbing polymeric material comprises units of a polymerizable UV-absorbing compound, a violet light-absorbing compound, and a monomer, and is capable of absorbing UV radiation, at least about 90 percent of light having wavelength of 425 nm, less than about 50 percent of light having wavelength of 450 nm, and less than about 30 percent of light having wavelength of 475 nm. Ophthalmic devices, such as contact lenses, corneal rings, corneal inlays, keratoprostheses, and intraocular lenses, are made from such polymeric material.
