Silicone hydrogel lens with a crosslinked hydrophilic coating

A readily-usable silicone hydrogel contact lens, comprising:

• a silicone hydrogel contact lens and a crosslinked hydrophilic coating thereon, wherein the crosslinked hydrophilic coating comprises from 5% to 80% by weight of polymer chains derived from a copolymer which is a polymerization product of a composition comprising from 0.1% to 30% by weight of one or more reactive vinylic monomer and (2) at least one non-reactive hydrophilic vinylic monomer, wherein said one or more reactive vinylic monomers are vinylic monomers having a carboxyl group or an amino group, wherein said at least one non-reactive hydrophilic vinylic monomer is selected from the group consisting of acrylamide, methacrylamide, N,N-dimethylacrylamide, N,N-dimethylmethacrylamide, N,N-dimethylaminoethylmethacrylate, N,N-dimethylaminoethylacrylate, N,N-dimethylaminopropylmethacrylamide, N,N-dimethylaminopropylacrylamide, and combinations thereof,
• wherein the readily-usable silicone hydrogel contact lens has (1) an oxygen permeability of at least about 40 barrers, (2) an elastic modulus of about 1.5 MPa or less, (3) a water content of from about 18% to about 70% by weight when fully hydrated, (4) a water contact angle of about 100 degrees or less, and (5) a good coating durability characterized by surviving a digital rubbing test.
