ABSTRACT:
A series of single-vision ophthalmic lenses for use in the correction of vision for myopia, hypermetropia, or astigmatism is described in which the series design is selected for the economic manufacture of, for example, thermoplastic ophthalmic lenses using injection molding. Injection molding methodology, when utilized appropriately, permits simplifications in the primary and secondary manufacture of ophthalmic lenses not usually practical when using other commonly-understood means of lens manufacture. Benefits of the lens series described include enhanced productivity of primary manufacture, improved cosmesis in certain types of secondary manufacture, and simplification of certain types of secondary manufacture that add further benefits to ophthalmic lenses following primary manufacture.
