ABSTRACT:
A copolymer for making contact lenses comprises, by weight, from about 5 to about 85 percent of a polymerizable fluoromonomer, and from about 5 to about 75 percent of a polymerizable hydrolyzable silicone monomer. A polymerizable hydrophilic monomer can also be included. Additionally, an initiator and a crosslinker are usually preferably employed, but the initiator is not needed when polymerization is aided by radiation from a radioactive source such as cobalt-60.
