    摘要: Ophthalmically acceptably wettable silicone hydrogel contact lenses are described. The lenses are derived from a polymerizable composition including 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 1 of formula (1) is an alkyl group having from 1 to 4 carbon atoms, and each R 2 of formula (1) is independently either a hydrogen atom or a methyl group, the first siloxane monomer having a number average molecular weight of from 400 daltons to 700 daltons; and a second siloxane monomer having a number average molecular weight greater than 7,000 daltons; wherein a total amount of siloxane monomers present in the polymerizable composition is from 30 unit parts to 50 unit parts; the lenses also include units derived from at least one hydrophilic amide monomer having one N-vinyl group that is present in the polymerizable composition in an amount from 30 to 60 unit parts. The lenses have ophthalmically acceptably wettable lens surfaces when fully hydrated. Batches of silicone hydrogel contact lenses and methods of making silicone hydrogel contact lenses are also described.
