    摘要: Disclosed is a method for determining at least one geometrico-morphological parameter of a subject for determining a vision correction equipment, wherein the following steps are performed: a) determining the height of one of the eyes of the subject (P) relative to a reference horizontal surface; b) placing a visual target in front of the head (HP) of the subject (P) at a predetermined position, this predetermined position being determined taking into account the height of one of the eyes of the subject relative to the reference horizontal surface, determined in step a); c) while the subject gazes at the visual target placed at the predetermined position in step b), capturing an image of the head (HP) of the subject (P) with an image capture apparatus (50); and d) deducing from the image captured in step c) the at least one geometrico-morphological parameter.

    摘要: 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.
