Methods of forming an ophthalmic lens precursor and a lens

摘要

A method of forming an ophthalmic lens precursor, the method comprising the steps of positioning a single substrate with an optical quality area in contact with a volume of reactive mixture; and transmitting sufficient actinic radiation through the single substrate to polymerize a portion of the volume of reactive mixture and form the ophthalmic lens precursor wherein the ophthalmic lens precursor comprises a first surface portion along the optical quality area and a second surface portion that is free-formed.
