ABSTRACT:
Two compounds, which are derivatives of 2(2-hydroxyphenyl) 2H-benzotriazole, are copolymerized with hydrogel forming monomers to form ultraviolet absorbing hydrogels. These hydrogels have many potential applications. For instance, they can be used to make contact lenses and intraocular lenses which are particularly useful for aphakics.
