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 7):
The method according to  claim 1 , wherein the curvature profile is determined by determining a cubic spline from the first boundary line to the second boundary line, wherein the cubic spline includes a plurality of sections each described by a cubical polynomial, and wherein the cubical polynomials are determined section-wise from the first boundary line to the second boundary line such that a sagittal height, a slope, and a curvature of the back surface along the carrier line are continuous, and the curvature gradient is reset to the desired constant curvature gradient for each polynomial at the radially inwards end of each section.
