According to the method and apparatus, a primary direction of sight −eζ(1,p) of the first eye for at least one primary evaluation point ib(1,p) of the first spectacle lens is determined and a corresponding primary direction of sight −eζ,k(2,p) of a second eye of the spectacle wearer that corresponds to the primary direction of sight −eζ(1,p) of the first eye in the specific situation of wear is also determined. Furthermore, a first primary merit function for at least one surface of the first spectacle lens is minimized, in which the first primary merit function for the at least one primary evaluation point ib(1,p) of the first spectacle lens takes into account a correction of a first primary transformed astigmatic refraction by the first spectacle lens in the specific situation of wear such that the first primary transformed astigmatic refraction depends on the corresponding primary direction of sight −eζ,k(2,p) of the second eye.

    摘要: A method and apparatus for creating a progressive spectacle lens design by transforming a starting design. The starting design is defined to include specifications for the course of a principal line and specification of at least one base target isoastigmatism line with a constant base target astigmatism, in which the base target isoastigmatism line passes through a first predetermined control point {right arrow over (r)}1=(u1,y1). The method and apparatus transform the starting design by shifting the first control point {right arrow over (r)}1=(u1,y1) along a predetermined or predeterminable curve, taking into account the design and/or the spectacle lens wearer-specific data; modifying the course of the base target isoastigmatism line such that it passes through the shifted first control point {right arrow over (r)}′1(u′1,y′1); and calculating a target astigmatism distribution A(u,y), which exhibits the modified base target isoastigmatism line. Furthermore, the method and apparatus are provided to create the spectacle lens on the basis of the progressive spectacle lens design.
