FINISHED OPHTHALMIC LENS AND CORRESPONDING METHODS

摘要

Finished ophthalmic lens and corresponding methods. Finished ophthalmic lens that has a concave face and a convex face and an external perimeter (1) and that furthermore has: a thickness within a pre-established range; a central working area (3) that complies with a specific pre-established ophthalmic prescription, defined by a machined surface, and which has a working perimeter (5) that coincides with the perimeter of a specific pre-established frame; and an outer, transition area that connects the working perimeter (5) of the central working area (3) to the outer perimeter (1). The transition area (7) comprises a transition surface that extends as a continuation of the machined surface and extends as far as the outer perimeter (1) and is continuous, and the derivative thereof is continuous at all the points thereof, including the line connecting between the transition surface and the machined surface.
