Summary:Method for determining a lens element intended to be mounted on a spectacle frame (10) and to be worn in front of an eye of a wearer, the lens element comprising;- a refraction area (12) having a refractive power based on prescribed refractive power Px for said eye of the wearer, the refraction area comprising at least a central zone (16),- a plurality of optical elements (14) having an optical function of not focusing an image on the retina of the eye of the wearer,wherein the method comprises:- obtaining frame data representing the spectacle frame on which the lens element is intended to be mounted;- obtaining wearer's data representing at least one parameter of the face of the wearer;- determining fitting data representing the spectacles positioned on the face of the wearer based on the frame data and the wearer's data; and- optimizing at least one parameter of the optical elements based on the fitting data.
