Abstract
In a method for determining at least one fitting parameter for a spectacle lens received in a spectacle frame, an image, lying in an image plane, of at least one portion of a spectacle frame worn by a subject is acquired. When acquiring the image, the inclination of the image plane about a horizontal axis which is parallel to the image plane is established and, in the process, the at least one fitting parameter is established from the acquired image of the portion of the subject with the spectacle frame worn by the subject and the established inclination of the image.
