发明名称 Method for lathing a lens
摘要 A method of lathing a lens, especially a contact lens, involves attaching the cylindrical blank of lens material to a first block of machineable plastic material, lathe cutting a desired first lens surface in the cylindrical blank, attaching the machined first lens surface of the blank to a second block, lathe cutting to remove the block of machineable plastic material, and lathe cutting a desired second lens surface in the blank. Both the first and second blocks may be adhered to the lens blank with an adhesive curable by ultraviolet radiation, and a two-piece block, composed of a head section and a body section, is disclosed.
