Embodiment Construction

[0044] The device for implementing the method for determining the dominant eye of a spectacle wearer 1 comprises a target 2, means 3, 4 for shielding at least one eye of said wearer 1, and is equipped with an optical window 6 and a magnetic gyroscope Tablet computer 5,50 of type 3D electronic sensor. Said sensor is connected to a processor integrated in a tablet computer equipped with a signal processing module, in particular making it possible to evaluate during the different steps of the method for determining the dominant eye according to the invention, The sign, amplitude, direction, duration and acceleration of the movement of the tablet computer 5,50.

[0045] Preferably, a single axis X of the 3D electronic sensor fixed to the tablet 5, 50 (corresponding to the axis X of horizontal movement of said tablet 5, 50) is preferred for measurement. For example, measurements of the acceleration of the tablet computer 5, 50 along the transverse axis X are recorded every 41 ms o...

Abstract

The invention relates to an apparatus for implementing a method for determining the dominant eye of a person (1) wearing glasses, comprising a target (2), a means (3, 4) for covering at least one eye, and a viewing device (5, 50) provided with an optical window (6). The main characteristic of the apparatus according to the invention is that the viewing device (5, 50) comprises an electronic sensor allowing the identification of the direction of displacement of said viewing device (5, 50) during stages for viewing the target (2) during said method.

Description

technical field [0001] The invention relates to a device for determining the dominant eye. The present invention relates to the field of personalization of corrective eyeglasses, and more specifically, to a device capable of determining the eye dominance parameter of the eyeglass wearer, also called "eye dominance". The invention also relates to a method for measuring this dominant eye by means of said device. Background technique [0002] Such methods and apparatus already exist. Mention may be made, for example, of patent application FR2972339, which describes a method for determining the dominant eye of a spectacle wearer by means of a sighting device equipped with an optical window and a system for acquiring images. The principle of such methods is based on the wearer viewing a target through the optical window and acquiring an image showing the position of the wearer's face and the optical window while the wearer is viewing the target. Processing the obtained images ...
