Abstract
A method for manufacturing a spectacle lens, in which at first a semi-finished uncut spectacle lens (hereinafter referred to as a blank) is produced, i.e. a spectacle lens having merely one finished optical surface (hereinafter described as base surface); subsequently a prescription-optimized surface is computed according to the data of a spectacle lens prescription; and then the prescription-optimized surface is finished according to the computed data. The invention is characterized by the following method steps: after the production of the semi-finished spectacle lens the base surface is measured; the prescription-optimized surface is computed and finished taking into account not only the individual data of the spectacle prescription, but also the actual shape of the base surface.
