    摘要: Molded ophthalmic lenses with improved optical qualities can be manufactured at high volumes at low costs to provide single-use lenses. These ophthalmic lenses are lenses for examination or treatment of the interior of an eye, are formed of an optical grade plastic, and have a ring portion integral with an optical portion. The ring portion extends from and circumferentially around the optical portion and the height of the ring portion is less than the thickness of said optical portion. These features reduce production costs and improve the optical quality of the lens including allowing any debris, bubbles and the like that tend to adhere to the surface of the mold during the molding process to collect away from the optical centerline of the lens so as to improve the optical quality of the molded ophthalmic lens and minimizing shrinkage during the molding process.
