Abstract

Ultraviolet light absorbing polymer compositions comprising copolymers of 2-Hydroxy-5-acrylyloxyphenyl-2H-benzotriazoles with one or more other monomers copolymerizable therewith, particularly acrylic monomers are useful in the manufacture of occular devices, particularly intraoccular lenses and contact lenses. Polymers of the disclosed benzotriazoles may be added to other organic materials to impart ultraviolet absorbing properties thereo.
