Abstract: Disclosed is a binocular optoelectronic device wearable by a user for measuring a light sensitivity threshold of the user, including: a diffuser configured to face eyes of the user; at least one light source for emitting light toward the diffuser. The diffuser includes predetermined parameters allowing to provide a quasi-homogeneous light diffusion to at least one eye of the user from light emitted by the at least one light source.

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 implemented by computer means for determining an oriented 3D representation of the head of a person in a natural visual posture, including receiving a first dataset corresponding to a first 3D representation of the head of the person in a first frame and the position of the rotation center of at least one eye of the person in said first frame, determining a second dataset corresponding to the orientation of the head of the person in a natural visual posture in a second frame, and determining an oriented 3D representation of the head of the person by orienting the first 3D representation of the head of the person based on the orientation of the head of the person in a common frame.

Abstract: Disclosed is a method for determining at least one visual behavior parameter of a person. The method includes the following steps: a step of encouraging the person to perform a visual test during which he observes at least one target position, a step of measuring an item of data that is representative of at least one viewing direction of the person during the visual test, a step of determining a reference viewing direction on the basis of the representative data measured, and a step of positioning, relative to the reference viewing direction, at least one measured target position that is determined, in a reference marker associated with the head of the person, on the basis of the data that is representative of the viewing direction of the person measured during the visual test.

Abstract: The invention concerns a method for determining a light filter for a spectacle lens for improving or maintaining the visual comfort of an individual wearing spectacles, comprising the steps: a) collecting data relating to the needs or uses of the individual; b1) selecting a test filter on the basis of a predefined criterion; b2) selecting, as a function of the collected data, a luminous scene comprising an image determined as a function of the needs or uses, and a light source generating a visual discomfort for the individual not equipped with a filter; c) placing of the individual by presenting him with the luminous scene through the test filter; d) evaluating said criterion; e) comparing the result with a predetermined threshold; f) determining the suitable light filter as a function of the result. The invention also concerns a display device and a virtual reality helmet designed for said method.
