    Abstract: An optical lens intended to be placed before a wearer's eye and having a front surface and a rear surface, the rear surface being the surface intended to be the closest to the wearer's eye when the optical lens is placed before a wearer's eye, the optical lens having a mineral glass element on the front surface and further comprising an eye protector that is configured to prevent any piece of the mineral glass element from reaching the wearer's eye when the element is broken, said eye protector comprising a polymer wafer arranged on the rear surface.

    Abstract: Disclosed is a holding system for supporting a wafer having a first surface, a second surface and a third surface joining the first and second surfaces, and an optical element having a first surface, a second surface and a third surface joining the first and second surfaces, the holding system including: a support including first support unit configured to support the second and/or third surface of the wafer and second support unit configured to support the second and/or third surface of the optical element; a positioning unit configured to position the second surface of the wafer relative to the first surface of the optical element; and a mechanical unit configured to move the first and second support units one relative to the other so as to move the second surface of the wafer and the first surface of the optical element to form an optical system.

    Abstract: A method and an optical system adapted for a wearer having an ophthalmic prescription. The optical system includes an optical device having a planar optical function, and an optical lens having an optical function based on the prescription of the wearer. The rear face of the optical device is attached to the front face of the optical lens, the optical device having at least one mechanical reference so as to allow an accurate relative position of the optical device and the optical lens.

    Abstract: A method for manufacturing an optical article including the following steps: a. providing a first substrate with a main surface, b. depositing a second substrate on the main surface with an adhesive layer so that the space between the first substrate and second substrate is filled by the adhesive layer, c. curing the adhesive layer to induce a polymerization of the adhesive layer, wherein a tension step takes place after steps a. and b., and before step c., the tension step including applying symmetrically a tension, preferentially with a central symmetry, preferentially a radial isotropic tension or an ortho-distributed symmetrical tension, on the edges of the second substrate sensibly in a tension plan parallel to a plan representative of the main surface.
