System and method for manufacturing a lens, such as an ophthalmic lens |
摘要 |
A system and method for manufacturing an ophthalmic lens is described. In some examples, the system applies a back surface to a lens blank that includes an aspherical curve having two radii of curvature. In some examples, a back surface of a peripheral portion of the lens follows the curvature of a front surface of the lens in order to establish a rounded, non-sharp edge to a lens blank used during the manufacturing process of a prescription eyeglass lens. |
