A method for forming an optical layer having an aspheric surface on a given surface area of a glass optical element to change the optical performance characteristics of the glass element. A cavity having a shape complementary to that of the aspheric surface is first formed in a tool and afterwards plated with at least one metal release layer preferably of silver. The cavity is then filled with a UV curable epoxy and then brought into registration with the optical element. The epoxy is then hardened by exposure of the epoxy to ultraviolet radiation. Tool and element are then separated and the metal release layer, which adheres to the epoxy, is then chemically removed.
