Summary:The current invention is directed to a computer-implemented method for providing a lens shape for an ophthalmic lens. 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. Further, there is provided an ophthalmic lens, in particular a spectacle lens. Further, a method for minimizing the difference in thickness between two ophthalmic lenses for the same spectacles. A computer program product and a machine readable storage medium are provided as well. (Fig. 2)
