Beschreibung
Zusammenfassung:	A spectacle lens which has permanent markings is mounted on a mounting, in particular a suction mounting. The apparent location of the permanent markings is detected on the spectacle lens with a detection device. Additionally, the spectacle lens is illuminated eccentrically with respect to an optical axis of the detection device using eccentric light sources. Reflections from the lights sources on the spectacle lens are likewise detected. On the basis of the detected reflections and the apparent location of the permanent markings, the position and/or orientation of the mounted spectacle lens are determined.
