Abstract

Improvements in the manufacture of contact lenses, characterized in that said lenses are formed from a hydrogel of a copolymer of an acrylate or hydroxyalkyl methacrylate and a copolymerizable vinyl monomer, which has an affinity for water, in its polymerized state, greater than the affinity of the hydroxyalkyl acrylate or methacrylate homopolymer, said copolymer having been crosslinked with a difunctional or polyfunctional vinyl or vinylidene compound.
