A hydrogel copolymer for making contact lenses comprises, by weight, about 5 to about 85 percent of alpha -methylene-N-methylpyrrolidone or glycerdyl methacrylate and mixtures thereof from about 5 to about 35 percent of N,N-dimethylacrylamide, from about 5 to about 60 percent of a polymerizable fluoromonomer, and from about 1 to about 15 percent of a polymerizable hydrophobic non-hydrolyzable silicone monomer. An initiator and a crosslinker are usually preferably also employed. |
