Eyewear of the present disclosure may include a frame having left and right rims, and a central bridge portion coupling the left rim to the right rim. A lens retainer has a first end pivotably coupled to an upper member of the central bridge portion and a second end releasably latched to a lower member of the central bridge portion. A lens is disposed on a front side of the eyewear frame and clamped to the frame by the lens retainer.

A method for purifying powdered silicon carbide is in the form of a starting material to form a silicon carbide having a purity of at least 99.9%. This method has the following method steps: providing a starting material having a grain size of less than 100 μm and a silicon carbide content with at least 98% purity; and heating the starting material in a vacuum or oxygen-free atmosphere to a temperature above 1700° C. over a period of at least 8 minutes.

Eyewear having a stereoscopic display including a lens system, and a push-pull lens set including prisms to produce a binocular overlap of two images that coincides with an accommodation plane. The overlap of two virtual images generated by a respective display as seen by the user's two eyes provides user comfort. The stereoscopic display may have a single accommodation plane, where the binocular overlap of the two virtual images depends on the location of the accommodation plane and the depth of the content formed by disparity in the two images. By providing the content at or near the location where the virtual images are at least substantially overlapped, the user viewing comfort is improved. The binocular overlap is controlled by tilting or steering the virtual images inward, such that the overlap occurs at the accommodation plane.

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.

A glasses frame structure includes a chassis, a pair of temples, a pair of hinges, and a plurality of fasteners. The chassis has a pair of front rims and a pair of side rims respectivey next to the front rims. Each of the side rims of the chassis can receive a first side lens. Each temple has a rimmed portion adjacent to one of the side rims of the chassis. The rimmed portion of each of the temples can receive a second side lens. The hinges can pivotally connect the temples to the chassis. Some of the fasteners can fix the hinges and the first side lenses to the chassis, while some of the fasteners can fix the hinges and the second side lenses to the temples. With the glass frame structure, the side lenses can be installed more easily and firmly.
