Zusammenfassung:A method of forming an ophthalmic lens, the method comprising the steps of forming an ophthalmic lens precursor with a first surface and a second surface via exposure of a reactive mixture to a first actinic radiation through a substrate; flowing a first portion of fluent material comprising the second surface of the lens precursor during a dwelling period; and exposing the lens precursor to an exposure to a second actinic radiation to form the ophthalmic lens.
