Provided is a lens that includes a lens body and an internal electrode at least a part of which is exposed to an outer edge part of the lens body. The lens is configured so that in the outer edge part of the lens body, the shape of a first region that includes an exposed part where the internal electrode is exposed and the shape of a second region that does not include the exposed part are different. This configuration makes it possible to provide a lens that can be easily attached to a frame.

The myopic sunglasses provided by the present application are convenient to wear, firm in structure and not easy to be damaged or scratched.

A glasses structure comprises a main body and a sub-frame assembled at the rear of a lens of the main body. The inner surface of a frame body of the sub-frame is attached with a pad, which pad is formed with an upper contact portion and a central contact portion corresponding to the upper edge and the central shape of the frame body. Two nose pieces are formed at the both sides of the central contact portion of the pad, and the upper contact portion of the pad are respectively contacted with the user's nose and forehead to avoid pain when the user wears the glasses. Furthermore, the colored and patterned frame body of the sub-frame is shown from the transparent lens of the main body, whereby the glasses with suitable color and pattern being chosen to dress with the user's clothes and style, increasing the user's fashion and beauty.

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.

A method of manufacturing an optic includes disposing electronic circuitry on a substrate. The method also includes depositing a first resin on the first side of the electronic circuitry and curing the first resin to form a first optical segment. The method further includes depositing a second resin on the second side of the electronic circuitry and curing the second resin to form a second optical segment. The first and second optical segments encapsulate the electronic circuitry. The first resin and the second resin can include multiple droplets of resin, thereby reducing mechanical force imposed on the electronic circuitry during printing and allowing conformal contact between the resin and the electronic circuitry. Accordingly, electronic circuitry of smaller dimension can be used to form the electronic eyewear.

The utility model discloses glasses with replaceable lenses, and the technical scheme of the glasses comprises a glasses frame, glasses legs connected to two sides of the glasses frame, and a lens assembly detachably fit with the glasses frame, the lens assembly comprising a frame and a lens; the frame is provided with an insertion end; the glasses frame is provided with an insertion groove in inserting fit with the insertion end; a clamping groove adapted to the clamping piece is arranged on the side wall of the insertion groove is provided with a clamping piece; the side wall, opposite to the clamping piece, of the insertion end; the clamping piece is in elastic clamping fit with the clamping groove, and the utility model is simple in structure and easy to detach.

A frame for spectacles with magnifying lenses includes a magnifying eyepiece for mounting on each lens. The frame includes: a front mount including, for each lens, a respective slot extending between a central region of the nose support mount and an opposite lateral region of the mount, each slot being configured to receive a portion of a respective lens-carrying support, partially surrounding a peripheral edge portion of the lens, and fixing means for fixing the lens-carrying support which is received in the respective slot to the front mount.

The lens-carrying support is received in the corresponding slot with a coupling play transverse to the front mount, and the fixing means are configured to fix each lens-carrying support to the front mount in a preselected relative positioning which is allowed by the coupling play, making the orientation of each lens adjustable with respect to the front mount.

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.

A lens that includes an electroactive region where an optical characteristic changes by electric control comprises: a transparent substrate; a second transparent substrate disposed facing the first transparent substrate; and an intermediate layer disposed between the first transparent substrate and the second transparent substrate; and including a mark including information.

Self-locking eyeglass system, comprising at least one locking element and at least one frame element, wherein the frame element additionally comprises a connection element, which is intended for connecting with a locking element, and wherein the frame element is non-interrupted in its external circumference, and wherein the connection element is provided on the inner side, wherein the self-locking eyeglass system additionally comprises two hinge elements, which each comprises an adapter element, which matches a recess in the frame element, wherein each hinge element has a connection element, which coincides with the frame element's connection element, when the hinge elements are mounted in the at least one frame element's recess, and wherein each hinge element is secured to the at least one frame element by a locking element, whereby a convenient, flexible and uncomplicated way to assemble, separate, replace and service a self-locking eyeglass system is achieved.
