A computerized eyewear retrofit kit for use with an eyewear frame comprises an elongated body having a first end comprising a first end surface and a connector that is configured to pivotally couple to an eyewear frame, and a second end configured to rest on an ear of a wearer wearing the eyewear frame. At least one processor is mounted in the elongated body and is coupled to a rechargeable power source mounted in the elongated body. At least one sensor is coupled to the elongated body and operatively coupled to the at least one processor. A charging port is formed in the elongated body first end surface that is configured to receive a charging cable, wherein when the computerized temple is coupled to an eyewear frame using the connector and the elongated body is substantially perpendicular to a rear surface of the eyewear frame, the charging port is hidden.

An eyeglasses assembly structure is revealed. A pivot member which is pivotally connected to a first assembly portion of a frame is inserted and mounted in a switch member. A first rib and a second rib are opposite to each other and disposed on a second assembly portion at a front side of a temple. The first rib is mounted into a first mounting groove at one end of the pivot member. A positioning flange is formed on the second rib and inserted through an opening of the switch member to be mounted in a second mounting groove on the other end of the pivot member. When the switch member is rotated an angle to be staggered or aligned with respect to the positioning flange of the second rib, the temple is firmly fixed to or separated from the frame. Thereby parts are assembled and replaced easily and conveniently.

This eyewear is provided with: a front having a nose contact part; a temple, one end of which is coupled to one end of the front via a coupling part; an electric device; and a noncontact electricity reception part that receives, from outside, electricity to be supplied to the electric device, wherein the noncontact electricity reception part is disposed in a region located within the temple, and the length between the noncontact electricity reception part and the hinge is shorter than the length between the nose contact part and the hinge.

A slip-resistant eyewear system comprising an eyewear frame generally comprises first and second hinges coupled to the eyewear frame which are also coupled to first and second tension adjusters. First and second bows are coupled to first and second tension adjusters. The system may comprise an eyewear retainer comprising a first end configured to couple to the first bow and a second end configured to couple to a second bow such that a tension is maintained on the unitary eyewear retainer when the unitary eyewear retainer extends around a back of a head of a user.

Systems, devices, and methods for wearable heads-up displays (WHUD) are described. A WHUD includes a front frame with two openings each with one recess which extends along at least a portion of the periphery of the openings, two arms including frame portions and temple portions, two lenses, a projector to generate light, and a holographic optical element (HOE) carried by a lens to redirect light to an eye of a user. Frame portions insert into the recesses and are held in place when the lenses are inserted into the recesses, wherein when the WHUD is assembled the projector and HOE are positioned correctly to create a display for the user. The assembled WHUD is inflexible where the front frame and arms are attached such that when worn the projector maintains a fixed position relative to the HOE and the display remains undistorted and visible to the user.

A modular eyewear system and apparatus is described. The apparatus includes eyepieces equipped with exchangeable arms which are configured to easily detach from a primary frame of the eyewear via quick-release clasps. Arms of the eyewear may be exchanged at will in order to accommodate differing styles, colors, patterns, materials, and textures in accordance with the style and immediate desire of the wearer. The quick-release mechanism includes an interlocking hook system which is manipulated via a lever by the user. Upon unlocking the mechanism, the arm of the frame may be removed easily and exchanged with one of a variety of compatible arms.

An eyeglass lens replacement assembly is revealed. A limiting slot is formed on each side of a frame and a limiting stopper is arranged in the limiting slot. A temple pivot member is mounted in the limiting slot. A lens is mounted to a lens connection portion of the frame and two sides of the lens are inserted into insertion slots of the temple pivot members. Each side of the lens is provided with a positioning dent which is locked with a positioning bulge of the insertion slot. A limiting bulge of a positioning portion pivoted on the temple pivot member is limited in a limiting notch of the lens while a locking recess of the positioning portion is locked and positioned by an inner wall surface of the insertion slot. Thereby the frame, the temple pivot members and the lens are combined with and connected to one another firmly.

A temple assembly for a pair of spectacles, including a spectacle temple body, a guide member, a first temple core, a second temple core, a first pivot; and a second pivot; the second temple core is elastically connected with the spectacle temple body, the guide member is sleeved on a periphery of the first temple core, and the first temple core includes a first connecting end and a second connecting end disposed opposite to each other, the second connecting end is pivotally connected to the second temple core via the second pivot, the first connecting end is pivotally connected to a pile head of a rim or an end hinge of a spectacle temple via the first pivot; the first pivot and the second pivot are disposed perpendicular to each other; and the guide member is elastically abutted the spectacle temple body.

An electronic case for electronic spectacles may include a base comprising a cavity formed therein. A first spectacle retention device may be located within the cavity. The first spectacle retention device may be configured to retain spectacles. An electrical control system may be included. An electrical connector may be configured to couple the electrical control system in electronic communication with the spectacles.

Spectacle frame (1) comprising: a front piece (10); a pair of temples (20), each temple (20) extending between a first end portion (21) associated with the front piece (10) and a second end portion (22) that can be positioned on the ear of a user; a pair of hinges (30) configured to rotationally bind each temple (20) to the front piece (10), each hinge (30) comprising: a pin (40) extended along a development direction (A-A) between a first end (40a) and a second end (40b), coupling devices (50) associated with the first end portion (21) of each temple (20) and configured to engage the corresponding pin (40); a cavity (60) located in the front piece (10), the cavity (60) comprising: a first wall (70) and an opposite second wall (80) spaced along a spacing direction (B-B); and blocking devices (90) configured to engage the ends (40a, 40b) of the pins (40), the blocking devices (90) being shaped to match the first end (40a) and the second end (40b) of the pin (40) to prevent the pin (40) from making rotational movements around the development axis (A-A) and translational movements with respect to the blocking devices (90) as a result of mutual engagement between the ends (40a, 40b) of the pin (40) with the blocking devices (90); the first end (40a) and the second end (40b) of the pin (40) are wedge-shaped.
