    摘要： A laminated optical lens having an edging-optimized laminar configuration and method for manufacturing same. The laminated optical lens includes an optical base lens and a film layered structure including an external film furthest from said lens. An adhesive layered structure is placed between the film layered structure and the optical base lens so as to permanently retain the film layered structure on the surface of the optical base lens. The laminated lens is manufactured by laminating a film layered structure having an external film to an optical base element with an adhesive layered structure. The external film has a thickness of at least 100 μιπ, and preferably a thickness in the range of 150 microns to 300 microns inclusive. The adhesive layered structure has a thickness in the range of 5 microns to 100 microns inclusive, and preferably of 25 microns to 50 microns inclusive

    摘要： The invention concerns a method of manufacturing an ophthalmic lens, comprising the steps of providing, mounting and blocking a substrate (10) on a machining support unit (65), surfacing an upper face (12) of said substrate, edging a peripheral edge (13) of said substrate, wherein said machining support unit comprises a surfacing member (40) and an edging member (30) which are separable, said surfacing member having a cavity (51) in which said edging member is located during said step of surfacing, said surfacing and edging members being configured so that said substrate is mounted and blocked on said machining support unit in a first predetermined position for the surfacing and the edging and, between said steps of surfacing and edging, the method comprises the step of withdrawing said surfacing member from said machining support unit by retaining said substrate on said edging member.

    摘要： Eyeglass lenses have at least a portion of their edge shaped to reflect light away from an eye of a wearer, such as the edge being disposed at an acute angle with respect to a principal axis of the lens, toward the back surface of the lens. Alternatively or additionally, the edge may include a plurality of edge surfaces disposed at an acute angle with respect to a principal axis of the eyeglass lens, toward the back surface of the eyeglass lens, or at least one edge surface may be disposed at an acute angle with respect to the front surface of the lens and at least one other edge surface may be disposed at an acute angle with respect to the back surface of the lens. As yet another alternative, the edge may be rounded with progressive angles to have an edge axis directed away from the wearer's eye.

    摘要： The present disclosure relates to a method of preparing a laminate or a laminated lens, comprising obtaining a first plastic substrate having a front surface and a back surface, treating the front surface of the first plastic substrate or the back surface of the first plastic substrate, and laminating a second plastic substrate on the treated front surface of the first plastic substrate or the treated back surface of the first plastic substrate. The treating may include applying a polyurethane resin to a surface of the first plastic substrate. The method may further comprise treating a surface of the second plastic substrate. The method may further comprise applying activator to the treated surfaces of the first plastic substrate and the second plastic substrate and laminating by apposing the treated surfaces of the first plastic substrate and the second plastic substrate.

    摘要： The present disclosure includes systems, devices, and methods for preventing contamination during formation of an optical article. In some implementations, a device for preventing contamination of a mold cavity during injection molding of a function wafer includes a containment band having an annular base that defines a first opening configured to receive a functional wafer. The device also includes one or more sidewalls that project a first direction from and surround at least a portion of the first opening. The one or more sidewalls may be configured such that, during formation of an optical article, a first portion of the functional wafer is in contact with the one or more sidewalls.
