Abstract:
1. A silicone hydrogel contact lens, comprising: a polymeric lens body that is the reaction product of a miscible polymerizable composition, said polymerizable composition comprising (a) a first siloxane monomer represented by formula (1): wherein m of formula (1) represents one integer from 3 to 10, n of formula (1) represents one integer from 1 to 10, R (b) a second siloxane monomer having a number average molecular weight greater than 7,000 daltons and being represented by formula (2): wherein R wherein a total amount of siloxane monomers present in the polymerizable composition is from 30 unit parts to 50 unit parts by weight; and (c) at least one hydrophilic amide monomer having one N-vinyl group, the hydrophilic amide monomer being present in the polymerizable composition in an amount from 30 unit parts to 60 unit parts by weight; wherein the contact lens has ophthalmically acceptably wettable lens surfaces when fully hydrated.
