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: A method for determining an optical system of a personalized progressive lens for a given wearer including: a) providing a mean direction of gaze determined for the wearer in a reference frame tied to the head of the wearer; b) determining a target value for at least one optical design parameter as a function of the mean direction of gaze determined in a); c) calculating the optical system of the progressive lens by an optical optimization procedure on the basis of target values, wherein the target value of each optical design parameter as a function of the mean direction of gaze determined in b) is a target value.

Abstract: A device for testing visual behavior of a person, including: an active display configured to display at least one visually predominant target in a plurality of positions that are variable over time and that are aligned along at least one line or column, and a unit for controlling the display. The unit is programmed so that consecutive display positions of the target follow, over time, a visual tracking protocol.

Abstract: A quality control method for optometric measurements includes the following steps: (a) recording, via computer, a first record (14) that includes at least one first value of a first identifier (12), enabling identification of a glasses wearer (1), and at least one other value of another identifier (13) enabling identification of an optometric apparatus (15) on a first optometric measuring site (10); (b) carrying out at least one optometric measurement (16) of the wearer; (c) sending, to a second site (20), a digital measurement data set (18) including the optometric measurement result from step (b), the digital data set being linked, via computer, to the first record; and (d) digitally processing the optometric measurement result from the first record (14) on the basis of a digital data reference system (45) and the values of the respective identifiers of the glasses wearer and the optometric apparatus of the first record.
