Abstract: A method for determining a fitted position of an ophthalmic lens to be mounted on a spectacle frame equipping a wearer, the fitted position being defined with respect to a wearer referential linked to the head of the wearer. The method includes defining at least one fitting criteria relating to the positioning of the ophthalmic lens with respect to the spectacle frame, determining frame 3D data at least partially representative of the geometry and position of the spectacle frame with respect to the wearer referential, determining lens 3D data at least partially representative of the geometry of at least a peripheral portion of the ophthalmic lens, and determining the fitted position of said ophthalmic lens with respect to the wearer referential using the frame 3D data and said lens 3D data to fit the ophthalmic lens within the spectacle frame meeting the fitting criteria.
