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

The invention relates to a method for specifying or determining the spatial position of a distance reference point and/or a near reference point of a progressive spectacle lens for correcting defective vision of a spectacle wearer. Said method consists of the following steps: individual data of the spectacle wearer is obtained; the individual vertical and/or the horizontal position of the distance reference point and/or the near reference point is determined or calculated in accordance with the determined individual data of the spectacle wearer.
