A method and device for calculating design parameters of a design of a progressive spectacle lens on the basis of a predetermined design polygon. The design parameters are calculated by specifying a point within the design polygon, in which the specified point defines the progressive spectacle lens design, and then determining a value of each design parameter at the specified point by an interpolation of at least part of the predetermined values at the corner points and, optionally, of at least part of the predetermined values of the design parameter at the at least one additional point.

Controlling designs using a polygonal design

A fast and efficient method for calculating or producing a spectacle lens design, as well as a method for manufacturing a spectacle lens according to the thus calculated spectacle lens design. Furthermore, a corresponding device is provided for manufacturing a spectacle lens, as well as corresponding computer program products and storage media.

Rescaling of the target astigmatism for other additions

The invention relates to a method for producing a progressive spectacle lens and to a corresponding apparatus, a computer program product, a storage medium and to the use of a progressive spectacle lens. The invention also relates to a method for producing a progressive spectacle lens for correcting defective vision of a spectacle wearer, comprising the following steps: the vertical and/or the horizontal spatial position of a distance reference point and/or a near reference point is specified or determined in accordance with individual data of the spectacle wearer; the spectacle lens is optimized or calculated such that the required dioptric effect of the spectacle lens is obtained in the individually determined distance reference point and/or the near reference point.

Method for calculating a spectacle lens having a variable position of the reference points
