An eyeglass structure includes a front light-penetrable portion flanked by two parallel guide walls each having a free end with a leg pivotal connection portion; a rear frame portion flanked by two sliding bodies each having a free end with a stop wall, with each sliding body disposed between the guide walls, and each stop wall between a corresponding one of the sliding bodies and a corresponding one of the leg pivotal connection portions; a demountable connection portion connected to the front light-penetrable portion and the rear frame portion; and two legs pivotally connected to the leg pivotal connection portions to stop the stop walls, respectively. Hence, the eyeglass structure enables the front light-penetrable portion and rear frame portion to be firmly coupled together.

Eyeglasses with a removable upper section are disclosed. The upper section is pre-attached to the lenses, such that the upper section of the eyeglasses is lowered, each with a respective lens, into a lower section of the eyeglasses. The upper section and lower section then form a continuous front face of the eyeglasses and are held together by connectors, such as magnets at extreme left and right sides of the upper sections to magnets within a cutout of the lower section adapted to fit the upper section there-within. This creates, at least a continuous top side and front side of the eyeglasses with lenses between the upper and lower portions thereof.

3D glasses including features for an enhanced viewing experience with lower production and operating costs for theaters. Keyed lenses and removable temples facilitate assembly and field repairs. Specific angles of lens placement and the provision of specific anti-reflective areas on the frames enhance the quality of the optical path content being viewed. RFID and radio chips increase accountability and collection of use statistics. Smooth areas enhance cleaning and lower the time and material costs for between use cleanings.

A pair of goggles with a lens assembly, a goggle frame, and at least one lens retention shelf is disclosed. The lens assembly includes a lens with a projection extending from the assembly. The goggle frame is made of a first material and has a frame aperture sized large enough to receive the projection from the lens assembly through it. The lens retention shelf is made of a second material harder than the first material and is disposed behind the frame. The first lens retention shelf includes a projection connector corresponding to the projection, the projection connector is aligned with the frame aperture and sized to receive and engage the projection with the goggle frame interposed between the lens retention shelf and the lens.

An eyewear lens coupling system and methods can be used during assembly of an eyewear. The system and methods may advantageously decrease optical distortion of the lens during assembly and use and/or may also advantageously increase retention of the lens to the eyewear frame to improve the overall quality of the eyewear.

Embodiments of the present disclosure are directed to eyewear (e.g., goggles, eye glasses, sun glasses, helmet shields, helmet visors, etc.) that can maximize the wearer's field of view when laminated lenses having electrically conductive functional layers (e.g., electrochromic and/or heating layers) are used. Improved field of view can be accomplished by means of reducing the bezel size of the laminated lens. For example, the bezel's non-transparent footprint can be reduced by stacking electronic components at a peripheral edge of the lens and securing with a frame assembly rather than a separate edge seal.

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.
