    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.

    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 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.

    摘要： An ophthalmic lens and a method for producing a progressive ophthalmic lens having at least one progressive surface, where by a calculation and optimization step in the production of the progressive lens is performed. The absolute value of the rotation |rot {right arrow over (A)}| and/or the divergence |div {right arrow over (A)}| of a vectorial astigmatism {right arrow over (A)} is as small as possible, and the absolute value |{right arrow over (A)}| of the vectorial astigmatism {right arrow over (A)} is proportional to the absolute value of an astigmatism in the use position of the progressive lens. The direction of the vectorial astigmatism {right arrow over (A)} is proportional to the axial position of an astigmatism in the use position of the progressive lens or a surface astigmatism of the at least one progressive surface of the progressive lens.

    摘要： The invention relates to a method for computer-assisted evaluation of the performance of progressive lenses, specifically while taking into account individual parameters of a given eyeglass wearer, the individual parameters including at least personal prescription data, in particular, additional spherical, astigmatic, and/or prismatic power, and/or personal wearer data for the eyeglass wearer, in particular, forward inclination, horizontal frame inclination, corneal vertex distance, and/or interpupillary distance. The method includes the following steps: determining the individual parameters; calculating a total performance factor P in each case for at least two quality classes of progressive lenses as a function of the individual parameters, the total performance factor P being correlated with the quality of the monocular visual acuity and/or binocular visual impression; — and outputting the calculated total performance factor P for the quality classes. The invention further relates to a device, a computer program product, a storage medium, and a graphical user interface.
