UV BLOCKING LENSES AND MATERIAL CONTAINING BENZOTRIAZOLES AND BENZOPHENONES

摘要

A contact lens or intraocular lens with enhanced ultra violet (UV) blocking to meet ANSI Class 1 specifications is disclosed which includes enhanced effective amounts of two different UV absorbing compounds. One UV absorber is a benzotriazole derivative, and the other UV absorber is a benzophenone derivative. The lens can be made of a hydrogel polymer formed by polymerizing one or more: monomers suitable for making such lenses.
