Eyewear having an optical waveguide communicating infrared light from a remote infrared emitter in the eyewear to an optical output coupler that uniformly illuminates an eye for tracking eye movement of a user. An optical input coupler couples a light beam emitted by the remote infrared emitter into the waveguide. The remote infrared emitter simplifies industrial design and is a single light source. The remote infrared emitter is not in a peripheral vision of a user's eye and improves a cosmetic impact.

Eyewear includes a frame, a pair of nose pads, and a pair of temples. Each of the nose pads may have a surface that faces a respective side of the wearer's nose. The eyewear may include a pair of nose grips disposed respectively on the nose pads, each of the nose grips defining a plurality of nose grip surfaces that face the respective side of the wearer's nose and are offset toward the wearer's nose from the surface of the respective nose pad. Each of the temples may have a surface that faces a respective side of the wearer's head. The eyewear may include a pair of temple grips disposed respectively on the temples, each of the temple grips defining a plurality of temple grip surfaces that face the respective side of the wearer's head and are offset toward the wearer's head from the surface of the respective temple.

A connection structure of a spectacle frame includes a frame, a connection member, and a temple. The frame is provided with a joint portion at each of both sides thereof, and a pivot shaft protrudes from each of upper and lower surfaces of a joint end of the joint portion. The connection member includes a body provided with a through-hole and having first and second abutting portions at front and rear sides of the through-hole. A head end of the connection member is provided with two shaft holes to respectively connect the two pivot shafts. The temple has a bending portion and an elastic piece extending from the bending portion and passing through the through-hole, such that the bending portion abuts against the first abutting portion and the second abutting portion to allow the temple relative to the frame to be folded inward or stretched outward.

Eyewear having one or more electronic devices stowable and deployable from storage cavities disposed in one or both temple arms of the eyewear are described. The devices are deployable through passages in the eyewear frame which are covered when the devices are in the stowed position. Devices may be changed either by removing and replacing a device or by removing and replacing a temple arm on a particular set of eyewear.

An eyeglass frame configured to hold corrective lenses therein is removably engageable with a protective lens. The protective lens has connectors on opposing ends which are engageable with first and second mounts engaged to the frame. A gap is formed between the protective lens and the front surface of the frame and is maintained by the engagement of the connectors with the respective mounts.

Disclosed are spectacles with replaceable pins, and belongs to the technical field of spectacles. The spectacles with the replaceable pins may include a spectacle frame and the pins, an edge of the spectacle frame being pivoted with a bolt, the bolt being inserted into an inserting hole of the pin, an elastic piece pushing a stopping block to enter into an opening on a side of the pin, and the spectacle frame being connected with the pins in a buckling manner. When a pressure is applied to the stopping block, the stopping block withdraws from the opening on the side of the pin when elastic force of the elastic piece is overcome and retracts into the accommodation cavity, in this way the buckling connection of the spectacle frame with the pins is removed, the pins and the spectacle frame are demountable, and it is convenient to replace the pins.

A disposable sleeve having an antimicrobial property for covering an arm of a pair of spectacles is presently disclosed. The disposable sleeve comprises a generally tubular body having an opening at least one end thereof for receiving the spectacle arm, and at least one antimicrobial agent containing component applied to a surface of the tubular body and/or dispersed therein to impart the antimicrobial property thereto.

An accessory eyeglasses retention device is integrally formed as a single elastomeric piece to secure eyeglasses to a wearer's head. The accessory eyeglasses retention device may include an elongated body extending between a front end and a back end, an adjustment mechanism including a first elastic strap and a second elastic strap, for example, longitudinally spaced apart on the elongated body and configured to hold a temple of the eyeglasses and adjustably position the elongated body relative to the temple. An angled flap is at the back end of the elongated body, extending and angled in a direction towards a portion of the wearer's head when the eyeglasses are worn on the wearer's head, and configured to securely retain the eyeglasses in a desired location on the wearer's head. Also, a lanyard attachment feature may be included at the back end of the elongated body and configured to attach the elongated body to an eyeglasses lanyard.
