ABSTRACT:
A method of making an ophthalmic lens including the steps of: preparing a polymerizable composition comprising excessive oxygen content; contacting the polymerizable composition with a gas that is inert or substantially inert to the polymerizable composition, and deoxygenating or partially deoxygenating the polymerizable composition; conveying all or part of the polymerizable composition to an ophthalmic lens mold; polymerizing all or part of the polymerizable composition and obtaining a polymeric ophthalmic lens, and the lens produced by such process.
