ABSTRACT:
A monomer for making a contact lens with improved oxygen permeability and stability is disclosed as having a first portion for increasing wettability and a second portion for increasing oxygen permeability. The first portion includes a side-chain functionality of the structural formula: ##STR1## and is hydrophilic. The second portion includes a siloxane moiety, and is usually hydrophobic.
Also disclosed is a cross-linking agent, a polymeric material for making contact lenses, a method for making the polymeric material, and a method for making contact lenses from the material.
