Abstract: User configurable eyeglasses employing retention of lenses in eyeglass frames using elastic cushion connectors may include a pair of lenses, each lens comprising at least one tab extending from the lens. An eyeglasses frame may define at least two fittings, each fitting positioned to receive one tab extending from a lens and each fitting sized larger than the tab to be received. A plurality of eyeglass lens retention cushions are each adapted to be disposed in one of the fittings and to receive one of the tabs. Each eyeglass lens retention cushion might have an elastic cushion body having a relaxed, or in situ, exterior size larger than an interior socket of the fittings and may have an interior opening with a relaxed, or in situ, size smaller than a tab extending from an eyeglasses lens.

Abstract: 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.

Abstract: Disclosed are methods (100) for preparing a laminate incorporable to a surface of an optical lens and methods (500) for incorporating the laminate on the surface of the optical lens. The laminate is prepared by laminating an optical film (202a, 202b), such as a polycarbonate film, on each side of a functional film using an adhesive that is capable of preventing optical defects in the laminates during a thermoforming process and an injection molding process. The adhesive has optimal thermomechanical properties that include that the optical film (202a, 202b) coated with said adhesive has a modulus by compression greater than 6×106 Pa, and preferably greater than 2×108 Pa at a temperature from about 130° C. to 150° C. The laminate is incorporated on the optical lens via thermoforming followed by injection molding with overmolding technology.

Abstract: 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.
