Zusammenfassung:The invention relates to an apparatus (800) for determining a refraction power distribution of a progressive spectacle lens (820) comprising- a first providing device (801), for providing a measure of at least one variable, characterizing the refractive power distribution, of a progressive spectacle lens of progressive spectacles worn in the past by the spectacle wearer- a second providing device (802), for providing current information concerning a visual impression of the spectacle wearer with the progressive spectacles worn in the past,- a third providing device (803), for providing current visual characteristics of the spectacle wearer,- a fourth providing device (804), for providing current individual needs of the spectacle wearer,- a determining device (806, 808), for determining a measure of a to-be-desired change of at least one variable of the progressive spectacle lens, characterizing the refractive power distribution, of the progressive spectacles worn in the past by the spectacle wearer,- a calculating device (810, 808) for calculating the refractive power distribution of the spectacle lens for the wearer based on the previously determined information.The invention also relates to a respective computer-implemented method and also a computer program for carrying out the method.
