Abstract:
A system and method for providing a discernable marking within a contact lens including forming a marking section substantially simultaneously with the formation of a bulk section of said lens. The marking section may be formed entirely during formation of the bulk section or may include preformed elements and may be extruded, inlaid, embedded, injected, or dyed within the bulk section. The bulk section may be formed as a rod, a sheet, or as an injection molded lens. The marking section extends substantially from the front to back surfaces of the lens.
