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. |
