ABSTRACT:
A method is provided for applying a coating to an ophthalmic device by applying a coating to a face of the mold used to make the device and partially curing the coating, or, if the viscosity is sufficiently high, leaving the coating uncured. Then the liquid used to form the lens is poured into the mold and the liquid and coating are concurrently cured.
