摘要： Silicone hydrogel contact lenses having ophthalmically acceptable levels of energy loss 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, R1 of formula (1) is an alkyl group having from 1 to 4 carbon atoms, and each R2 of formula (1) is independently either a hydrogen atom or a methyl group; the lenses also include units derived from a second siloxane monomer which is a dual-end methacrylate end-capped polydimethylsiloxane having a number average molecular weight of at least 7,000 daltons. Batches of silicone hydrogel contact lenses and methods of making silicone hydrogel contact lenses are also described.

摘要： Silicone hydrogel contact lenses are described. The lenses are derived from a polymerizable composition including 30-60 unit parts by weight of a hydrophilic monomer(s) having one N-vinyl group, 10 to 50 unit parts by weight of 2-hydroxyethyl methacrylate (HEMA), and a first siloxane monomer component comprising a siloxane monomer of formula (1) as described herein or a siloxane monomer of formula (2) as described herein or a siloxane monomer of formula (3) as described herein or any combination thereof, where the total amount of siloxane monomer(s) present in the polymerizable composition is from 15 to 40 unit parts by weight. Batches of silicone hydrogel contact lenses and methods of making silicone hydrogel contact lenses are also described.
