Abstract:
This invention discloses methods for generating one or both of an ophthalmic lens precursor with at least a portion of one surface free-formed from a Reactive Mixture. In some embodiments, an ophthalmic lens precursor is formed on a substrate with an arcuate optical quality surface via a source of actinic radiation controllable to cure a definable portion of a volume of Reactive Mixture.
