Abstract: Disclosed is a method for comparing first and second ophthalmic lenses, including: a first optical function providing step, during which a first optical function of a first ophthalmic lens LI is provided, the first optical function including at least a first set of values of an optical parameter Gj, the values of the first set of values corresponding to the values of the optical parameter of the first ophthalmic lens in a set of gaze directions, a similar second optical function providing step directed to a second ophthalmic lens L2, a subsets determining step, during which at least a first and a second subset of gaze directions are selected, a comparison step for each subset of gaze directions, an assignment step, during which a subset status is assigned to each subset of gaze directions, the subset status being selected among at least three levels.

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.
