    摘要: A method and apparatus for making a lens includes a front mold (90) which has a reflective, UV absorptive surface, a back mold (50) which is UV light transmissive and a gasket (60) which holds the molds and defines a lens forming cavity (78) therebetween which receives polymerizable resin material (130). The resin (130) in the lens forming cavity (78) is exposed to a source of UV light (20) to cure the resin (130) and form the lens. Photochromatic coatings can be applied to the lens and cured.
