Abstract
The local refractive power or the refractive power distribution of a spectacle lens is measured. A first image of a scene having a plurality of structure points and a left and/or a right spectacle lens of a frame front is captured with an image capturing device from a first capture position having an imaging beam path for structure points, which extends through the spectacle lens of the frame front. At least two further images of the scene are captured with the image capturing device from different capture positions, one of which can be identical with the first capture position, without the spectacle lenses of the spectacles or without the frame front containing the spectacle lenses having the structure points imaged in the first image, and the coordinates of the structure points in a coordinate system are calculated from the at least two further images of the scene by image analysis.
