At least two calibrated images, recorded from different recording directions, of the head of the subject wearing the spectacle frame are provided, wherein geometric parameters are established by geometric position determination. The geometric parameters describe the position of the eyes and the geometry of the spectacle frame, and the centration parameters are calculated from the geometric parameters. Further, a three-dimensional model for the spectacle lenses, which are to be received in the spectacle frame, is fitted to the geometry of the geometric parameters that describe the geometry of the spectacle frame."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Computer-implemented method for determining centration parameters","description":"Centration parameters for fitting spectacle lenses to a predetermined spectacle frame and to the head of a subject are determined with a computer-implemented method.
