Beschreibung
Zusammenfassung:	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.
