Abstract
Systems and methods of manufacturing ophthalmic lenses, for example, silicone hydrogel contact lenses, are provided. The present systems and methods provide certain amounts of ultraviolet light to contact lens mold assemblies that comprise a silicone hydrogel precursor composition. For example, the systems and methods may provide ultraviolet light at an intensity from 20 μW/cmto 4000 μW/cm. The ultraviolet light intensity can be provided as substantially uniform levels to provide consistent curing for batches of silicone hydrogel contact lenses.
