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 24):
A method for constructing a surface determined by carrier lines radially outwards of a prescription zone of an ophthalmic lens, the method comprising:\n aa) providing a plurality of carrier lines each extending from a carrier point in the prescription zone into a respective direction, wherein a curvature profile of the surface along each carrier line radially outwards of the prescription zone is provided by a cubic spline; bb) forming a first set of truncated Fourier series of a definite high order each approximating corresponding coefficients of a first spline for all carrier line directions, cc) forming a second set of truncated Fourier series of a definite low order each approximating corresponding coefficients of a second spline for all carrier line directions, and dd) determining a third spline sufficient to determine a surface height at any radial location within the range of the carrier lines for any specified carrier line direction by a weighted average of the first spline and second spline for that direction, where the weighting function is a specified polynomial function of the radial distance from the first boundary.
