Abstract
A method for optimizing an atoroidal surface of an optical lens, in particular a spectacle lens, having at least one plane of symmetry is characterized by a combination of the following features: dividing the atoroidal surface having at least one plane of symmetry into at least two regions separated by the at least one plane of symmetry; representing one of the separate regions (represented region) of this surface by a set of coefficients of B spline functions; computing sagittal heights of the represented region by B spline interpolation; computing sagittal heights in at least one other region by mirroring coefficients or coordinates at the at least one plane of symmetry; and optimizing the atoroidal surface only by varying the set of B spline coefficients of the represented region.
