ABSTRACT:
An improved soft contact lens material, existing as a hydrogel, is formed by a polymer containing a fluorinated monomer, a hydroxyalkyl ester of acrylic or methacrylic acid, and an N-vinyl lactam. The polymer may also contain other hydrophilic and/or hard hydrophobic monomers, crosslinking agents, and uv-absorbing agents. Contact lenses made of these combinations have high water of hydrations, are highly wettable, have extremely high oxygen permeabilities and are resistant to protein deposits and other forms of attached debris.
