Abstract
A method for determining at least one optical conception parameter for a progressive ophthalmic lens intended to equip a frame of a wearer, depending on the visual behavior of the latter. The method comprises the following steps: a) collecting a plurality of behavioral measurements relating to a plurality of gaze directions and/or positions of the wearer during a visual task; b) statistically processing said plurality of behavioral measurements in order to determine a zone of use of the area of an eyeglass fitted in said frame, said zone of use being representative of a statistical spatial distribution of said plurality of behavioral measurements; and c) determining at least one optical conception parameter for said progressive ophthalmic lens depending on a spatial extent and/or position of the zone of use.
