    Abstract: The invention relates to the field of management of an active lens and more particularly to a management system comprising an active lens (1), a first sensor (2) arranged to measure data relating to an incident light on the active lens, a control unit (4) designed for controlling the active lens according to data measured by the first sensor, wherein the management system further comprises a second sensor (3) arranged to measure data relating to a light transmitted from the incident light through the active lens, the control unit being further designed to adjust, according to said data measured by the second sensor, the control already performed according to said data measured by the first sensor. Thus the management system allows taking into account data relating to the light passing through the active lens as a feedback in order to finely control the active lens.

    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.

    Abstract: A method for providing a display device for an electronic information device configured to display a virtual image to a user, the electronic information device including an optical element having a nonzero optical power and configured to be positioned in front of an eye of a user, the display device including a light source and a guide element configured to guide optical beams emitted by the light source to the eye of the user to allow viewing of the virtual image, the method including: providing a value of a parameter of the virtual image; and determining an optimum value of a display parameter of the display device from at least one optical power at a point of the optical element and from the value of the parameter of the virtual image.

    Abstract: An optical article that includes an ophthalmic lens that includes a substrate, a first layer comprising liquid crystals being disposed on at least part of the substrate, and a first and a second electrode made of a conductive material, and a voltage source electrically connected to the first and second electrodes and configured to control an orientation of the liquid crystals depending on the voltage applied. The ophthalmic lens further includes a second layer made of photoconductive material placed between the electrodes, and the optical article further includes a light projector configured to project a light pattern on the second layer of the ophthalmic lens, the second layer being locally conductive when illuminated by the light pattern, the light pattern corresponding to a pattern of refractive index modification to be induced by the liquid crystals of the first layer.
