    • A method and apparatus for creating a progressive spectacle lens design by transforming a starting design. The starting design is defined to include specification of a principal line, specifications for target astigmatism values A(u=0,y) along the principal line, and specifications for the course of a base target isoastigmatism line, which is described by a one-dimensional function of the form uG(y)=ƒ(y). The method and apparatus transform the starting design by modifying the course of the base target isoastigmatism line uG(y)→u′G(y), and calculating the target astigmatism values A(u,y) of the spectacle lens design by an interpolation between the target astigmatism values A(u=0,y) on the principal line and the target astigmatism values A(u′G(y),y) on the modified base target isoastigmatism line. Furthermore, the method and apparatus are provided to create the spectacle lens for the wearer on the basis of the progressive spectacle lens design.

    • The invention relates in particular to a computer-implemented method for calculating or optimizing a spectacle lens, comprising the steps of: specifying at least one surface for the spectacle lens to be calculated or optimized; determining the course of a main ray (10) through at least one visual point (i) of the at least one surface; determining a first primary set (sio) and a second primary set (eiok) of coefficients of the local aberration of a local wavefront (18) going out from the at least one visual point (i) in a surrounding of the main ray (10), wherein the first primary set of coefficients (sio) defines the spherical and astigmatic aberration of the outgoing local wavefront and the second primary set of coefficients (eiok) defines at least one further higher-order aberration (k>2) of the outgoing local wavefront; specifying at least one function epk=ƒ(eok) which assigns a second secondary set of coefficients (epk) to a second primary set of coefficients (eok), said second secondary set of coefficients defining the higher-order aberration of a propagated wavefront; determining a higher-order aberration of a local wavefront propagated starting from the at least one visual point (i) along the main ray depending on at least the second primary set of coefficients (eiok) on the basis of the specified function epk=ƒ(eok); and calculating or optimizing the at least one surface of the spectacle lens taking into consideration the determined higher-order aberration of the propagated local wavefront.

    • A method and system for producing a first spectacle lens for a specific situation of wear for correcting at least a first astigmatic refraction of a first eye of a wearer, which has a first cylinder reference axis α0(1) in a reference direction of sight −ez(1) of the first eye. 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.
