    Abstract: A lens (1) includes a plurality of optical surfaces (S1, S2) each of which is made up of an alternation of active zones (ZA1, ZA2) and separation zones (ZS1, ZS2). The active zones of one of the surfaces are situated beside the separation zones of the other surface. The shape of one at least of the optical surfaces is then adapted into the separation zones in order to augment the acute angles that are situated at the convergence of active zones and separation zones. The lens can thus be made with improved accuracy with respect to a target optical function.

    Abstract: A lens element intended to be worn in front of an eye of a wearer comprising: —a prescription portion configured to provide to the wearer in standard wearing conditions a first optical function based on the prescription of the wearer for correcting an abnormal refraction of said eye of the wearer, and—a plurality of contiguous optical elements, wherein each optical element has a simultaneously bifocal optical function that provides simultaneously: —a second optical function in standard wearing conditions and—a third optical function of not focusing an image on the retina of the eye in said standard wearing conditions so as to slow down the progression of the abnormal refraction of the eye.

    Abstract: An optical device including an active programmable lens having an adjustable optical power depending on a prescription of a wearer and being relative to a vision distance and/or direction of an eye of the wearer, a vision sensor adapted to measure vision data relating to the vision distance and/or direction of the eye, and an optical power controller that includes a memory storing computer executable instructions and adapted to store measured vision data and two predetermined optical power states corresponding to an optical power relative to a range of vision distance and/or direction of the eye, and a processor for executing the stored computer executable instructions, which include instructions for adjusting the adjustable optical power between the predetermined optical power states with a resolution smaller than or equal to 0.25 D when the vision data passes from one range of vision distance and/or direction to another.

    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.
