    Abstract: The invention relates to a method for determining a fitted position of an ophthalmic lens (130) to be mounted on a spectacle frame (120) equipping a wearer (100), said fitted position being defined with respect to a wearer referential (XYZ) linked to the head of the wearer, said method comprising steps of: - 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 said spectacle frame with respect to said wearer referential; - determining lens 3D data at least partially representative of the geometry of at least a peripheral portion (140) of said ophthalmic lens; - determining said fitted position of said ophthalmic lens with respect to said wearer referential using said frame 3D data and said lens 3D data to fit said ophthalmic lens within said spectacle frame meeting said fitting criteria. The invention further relates to a system for implementing said method. The invention finally proposes an ophthalmic lens to be fitted on a spectacle frame adapted to be disposed on the head of a wearer and designed according to such method.
