ABSTRACT:
A soft hydrogel contact lens, is disclosed. The lens is derived from a crosslinked polymer comprising the reaction product of a monomer mixture comprising:
(A) a monounsaturated polyoxyethylene monomer;
(B) a diunsaturated polyoxyethylene monomer of relatively high molecular weight;
(C) a diunsaturated polyoxyethylene monomer of relatively low molecular weight; and
(D) a hydrophilic monomer selected from the group consisting of hydroxyethyl methacrylate, methacrylic acid, N,N-dimethylacryiamide, N-vinyl pyrrolidone, glycerol monomethacrylate, itaconic acid, and mixtures thereof.
