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.

[ What is claimed is:] [1.] An ophthalmic lens series comprising a plurality of unitary lenses formed of an optical material of known refractive index, each lens having an anterior surface characterized by an anterior base curve and a posterior surface characterized by a posterior curve, the anterior base curve being selected from a group consisting of less than 10 curves; andwherein the ophthalmic lens series spans a range of spherical prescriptive powers within a range of +6.00 diopters to -8.00 diopters, and the series comprises a group of lenses having a common anterior base curve, the group spanning a diopter range of lens sphere power of between about 1.00 diopter and 2.00 diopters.
