Abstract:
A computer-implemented method for providing a lens shape for an ophthalmic lens is disclosed. Further, there is provided a method for angular smoothing of a surface determined by carrier lines radially outwards of a prescription zone bordered by a first boundary line. In addition, there is provided an ophthalmic lens, in particular, a spectacle lens. Moreover, a method for minimizing the difference in thickness between two ophthalmic lenses for the same spectacles is provided. A computer program product and a machine-readable storage medium are provided as well.

Claim (Index 31):
A method for minimizing a difference in thickness between two ophthalmic lenses for the same spectacles, the method comprising:\n A) providing, for each ophthalmic lens, an original lens shape satisfying predetermined optical properties over the complete back surface and a modified lens shape having a front surface and a back surface, wherein the modified lens shape includes a predetermined shape of the front surface and a predetermined shape of the back surface within a prescription zone of the back surface bordered by a first boundary line, such that the ophthalmic lens satisfies the predetermined optical properties within the prescription zone, and an extension of the back surface radially outwards of the prescription zone by carrier lines; B) adapting the modified lens shape of the ophthalmic lens having a smaller maximum thickness by replacing the back surface with a combination of the original lens shape and the modified lens shape according to\n CS=OS+A \u00b7( MS\u2212OS ), \n \u2003wherein CS is a sagittal height of the combined back surface, OS is the sagittal height of the back surface of the original lens shape, MS is the sagittal height of the back surface of the modified lens shape and A is a value from and including 0 to and including 1, and C) optimizing A so that the difference in thickness between the two ophthalmic lenses is minimized.
