摘要:A method and mold assembly to control the polymerization of a moldedarticle. In one embodiment, an amorphous posterior mold comprising a non-criticalsurface having a controlled radius of curvature is used to produce molded articles. In analternate embodiment, ophthalmic lenses are produced using a posterior mold in whichthe concave surface of the non-critical surface is filled with a liquid having a similarrefractive index as the mold material. In still another embodiment, a positive lens isplaced at a predetermined distance adjacent to the mold assembly to alter theirradiation path to the mold assembly. In still another embodiment, a positive lens isplaced within the concave surface of the posterior lens.
