Abstract
Method (210) for determining at least one optical parameter (220, 220', ...) of at least one spectacle lens of a spectacle (118), wherein the method (210) comprises the following steps: a) Taking in at least one image (234) or at least one pattern (124) through one or both lenses (116) of a pair of glasses (118); and b) Determining at least one optical parameter (220, 220') of one or both lenses (116) of the spectacles (118) based on the at least one image (234) of the at least one pattern (124), characterized in that at least two data sets (242, 244, 246) for different characteristic values for the variation are extracted from the at least one image (234) of the at least one pattern (124) which has an optically detectable variation, and that at least one optical parameter (220, 220', ...) of one or both lenses (116) of the spectacles (118) is determined from the at least two data sets (242, 244, 246).
