Zusammenfassung:	In a method for checking the centration of at least one spectacle lens, the spectacle lens is arranged in a field of capture of an image capturer; at least one image of the spectacle lens is captured by means of the image capturer; and positions of functional engravings of the spectacle lens in the captured image are determined. Furthermore, at least one lens contour of the at least one spectacle lens in the captured image is determined and the centration of the spectacle lens is checked taking into account the determined positions of the functional engravings, the determined lens contour and a known, wearer-dependent target geometry of the centration.
