Abstract: A method for determining a pupillary distance of an individual, includes the following steps: —displaying an object on a screen located in front of the individual, the displayed object being positioned at a location in front of one eye of the individual; —instructing the individual to look with at least the eye at the displayed object; —acquiring at least an image of a part of the body of the individual including the eye; —determining the location of a plurality of specific features in the acquired image, one of the specific features being a pupil of the eye of the individual; and —calculating the pupillary distance based on the location of the plurality of specific features. A corresponding system is also described.

Abstract: Disclosed is a method for measuring the refraction of an individual by a refraction measuring appliance, including: an initial step of determining at least one initial value of a visuo-postural parameter of the individual; a step of processing the initial value in order to deduce at least one initial value of a regulating parameter of the refraction measuring appliance, the regulating parameter being associated with the visuo-postural parameter; a step of regulating the refraction measuring appliance according to the initial value of the regulating parameter; and a step of measuring the refraction of the individual by the measuring appliance regulated in this way. Also disclosed is a method for the optical design of an ophthalmic lens, and to a pair of glasses including such a lens.

Abstract: Disclosed is a method for measuring data for fitting an ophthalmic lens in a frame for a individual, including the following steps: a) placing the individual in a natural posture; b) displaying a visual target with adjustable position in the field of view of the individual; c) having the individual equipped with the frame adjust the position of the visual target in order to place it straight ahead from him; d) determining the intersection, with a surface representative of the lens once placed in the frame, of the line of sight of the individual looking at the visual target with its adjusted position and determining the data based on the intersection determined.

Abstract: A method for customizing a head mounted device adapted to generate a virtual image for a wearer, the method comprises: obtaining a 3D eye pupil position of the wearer in a reference frame and corresponding to a predetermined gaze direction, and customizing the head-mounted device based on the 3D eye pupil position so that the position of a focus area (EMB) at least partly coincides with the position of the eye pupil in the predetermined gaze direction, wherein customizing the head-mounted device comprises controlling a recording of a holographic mirror based on the 3D eye pupil position in the reference frame.

Abstract: The invention relates to a method for checking the correct assembly of a device consisting of a frame and of two corrective ophthalmic lenses. The main feature of a method according to the invention is that it includes the following steps: an initial step of determining at least one parameter which makes it possible to position the lenses in the frame relative to the face; a subsequent step of acquiring at least one image of the face of said wearer with said device, which shows centering and horizontal level marks; a step of comparing said at least one parameter determined during said initial step with the corresponding parameter deduced from said at least one image; and a step of making a decision regarding the correct assembly of the device.

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.
