More Information
Summary:Contact lenses, intraocular lenses and transparent plastic with enhanced UV blocking to meet ANSI Class 1 specifications include 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 lenses are made from a polymer that incorporates both of these UV absorbers.
