Abstract

Ophthalmically acceptably wettable silicone hydrogel contact lenses are described. The lenses are derived from a polymerizable composition including a first siloxane monomer. 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.
