Abstract: A lens element intended to be worn in front of an eye of a wearer having a first optical function, and comprising at least one activable optical element, wherein in a first state the at least one activable optical element contributes with the rest of the lens to focus the image of an object at distance on the retina of the wearer, and in a second state the at least one activable optical element has a second optical function of scattering light so as to slow down the progression of the abnormal refraction of the eye.

Abstract: This computer-implemented method for providing a finished single vision ophthalmic lens intended for a wearer, from a target lens having at least one complex surface, the finished lens having a rotationally symmetrical front surface, includes: providing wearer data or theoretical data; defining targeted optical or geometrical characteristics along a predetermined path on the target lens, based on the wearer data or on the theoretical data; determining the finished lens by: selecting an initial lens complying with the prescription data and having a rotationally symmetrical front surface and a predetermined curvature at a prescription reference point; defining a current lens as the initial lens; modifying a front surface definition of the current lens to reach the targeted optical or geometrical characteristics until an ending criterion is met; providing the finished lens as the current lens.

Abstract: A machine and method for obtaining a curved surface of a film structure that comprises a carrier layer and a functional film (212). The machine comprises an annular support member having a supporting face adapted for supporting the film structure, and an opening (10) that is covered by the film structure when said film structure is supported by the annular support member; a clamping system configured to clamp the annular support member and the film structure when supported by the annular support member; and a forming system configured to apply pressure, and preferably temperature, on the film structure so as to curve said film structure in or through the opening (10) of the annular support member. The opening (10) of the annular support member has a contour that is non-circular so that the obtained curvature of the functional film (212) corresponds to a target curvature.

Abstract: A monitoring equipment including an eyewear that includes a frame, at least one lens that is fixed to the frame and that is able to change the natural evolution of an optical deficiency, a wearing sensor able to determine if the eyewear is being worn by a wearer, and a processing unit that is programmed to acquire the data determined by the wearing sensor, deduce therefrom a parameter relative to the length of time the wearer has worn the eyewear during a predetermined period, and compare said parameter with at least a predetermined datum to determine a level of efficiency of the optical deficiency treatment.
