Abstract
Official abstract text for this publication.
Method for optimization of a progressive spectacle lens, which method comprises: defining a starting nominal astigmatism distribution for the spectacle lens; determining a transformed nominal astigmatism distribution and optimizing the spectacle lens on the basis of the transformed nominal astigmatism distribution, wherein the determination of a transformed nominal astigmatism distribution comprises multiplication of the maximum temporal nominal astigmatism of the starting nominal astigmatism distribution by a factor k as a result of which a modified maximum temporal astigmatism is obtained, wherein k is a function of a prescription value, and/or at least of one parameter of the spectacle lens or of the arrangement thereof in front of the eyes, and transformation of the starting nominal astigmatism distribution on the basis of the modified maximum temporal astigmatism.
First claim
Opening claim text (preview).
The invention claimed is: 1. A computer-implemented method for optimizing and forming an optimized progressive spectacle lens, comprising: specifying a starting target astigmatism distribution Ast target start for the progressive spectacle lens; determining a transformed target astigmatism distribution Ast target new , and optimizing the progressive spectacle lens on the basis of the transformed target astigmatism distribution, wherein determining a transformed…
