    Abstract: The invention relates to an optical device (10) adapted to be worn by a wearer comprising at least: —a programmable lens (20) having an adjustable optical function and extending between at least one eye of the wearer and the real world scene when the optical device is worn by the wearer, —an optical function controller (30) comprising —a memory (32) storing at least computer executable instructions; and —a processor (34) for executing the stored computer executable instructions so as to control the optical function of the programmable lens (20), wherein the computer executable instructions comprise instructions for adjusting the optical function of the programmable lens (20) over a period of time determined so that the wearer does not perceive the adjustment of the optical function.

    Abstract: Disclosed is a method for determining an eye parameter of a user of a display device, the eye parameter relating to a dioptric parameter of an ophthalmic lens to be provided to the user, the method including: a display device providing step, during which a binocular display device is provided to the user,—an image display step, during which an image is displayed to the user when using the display device; a display parameter modifying step, during which at least one parameter of the display device is modified so as to modify the virtual display distance of the perceived image, wherein the display parameter modifying step is repeated until image subjective quality of the perceived image is perceived by the user as optimal; and an eye parameter determining step during which an eye parameter is determined based on the parameter of the display device.

    IPC: G02C7/10

    Abstract: The disclosure relates to methods, controlling units, eyeglasses, computer programs and computer-readable storage media for controlling an optical transmission of a variable transmission ophthalmic lens. The method includes receiving from a light sensor a measured illuminance of the environment of a wearer, computing a change of illuminance measured during a predetermined time interval, comparing the computed change of illuminance with a first threshold, when the computed change of illuminance is greater than the first threshold, implementing first command configured for varying the transmission of the variable transmission ophthalmic lens from initial transmission value corresponding to a current transmission value to a first target transmission value, according to a first variation profile comprising a first phase during which the transmission overshoots the first target transmission value, and a second phase during which the transmission returns to the first target transmission value.

    Abstract: A method for measuring a distance separating a camera from a reference object including a predetermined number of corners arranged in a pattern and at least two reference points separated by a reference length. The method includes acquiring an image including the reference object with the camera, detecting corners in the image, attributing a class to each corner, based on an orientation of the corner, detecting the reference object in the image based on the corners and attributed classes, placing the reference points in the image based on the corners of the reference object and measuring an imaged length separating the reference points, and comparing the reference length to the imaged length and obtaining the distance separating the camera from the reference object.

    Abstract: Disclosed is a method for manufacturing an article made of a polymerized material including the steps of: —providing a vat of polymerizable material, transparent at least in the 400-800 nanometers wavelengths range, —irradiating the polymerizable material with a laser beam according to a predetermined pattern so as to polymerize the polymerizable material in order to form the article, the predetermined pattern being determined based on a three-dimension representation of the article with the positions in three dimensions of a plurality of volume units adapted to form together the article, the laser beam scanning the vat in three dimensions in order to be focused at each position of the volume units present in the predetermined pattern so as to initiate locally the polymerization of the polymerizable material at each of these positions.

    Abstract: Disclosed is a method of preparing an operation of surfacing of a lens blank to transform the lens blank into a generated lens having a predetermined prism corresponding to an inclination between a front surface and a back surface of the generated lens at least locally. The method includes: for a plurality of devices destined to interact with the lens blank during the operation of surfacing to manufacture the predetermined prism of the generated lens, attributing a priority order to each; based on the priority order, attributing to each device a prism portion which is zero or included in a respective range delimited by a respective minimum prism portion and a respective maximum prism portion, the prism portion representing contribution of the corresponding device to the prism of the generated lens, for further interaction of each device with the lens blank during the operation of surfacing.
