An assembly for eyeglasses temple includes a first connecting rod and a second connecting rod each having an elastic component, outer ends of the two elastic components are hooked to each other to cause the second connecting rod and the first connecting rod abut against each other. A protrusion is provided on an end portion of the second connecting rod, when the second connecting rod is rotated to a position perpendicular to the first connecting rod, the protrusion is inserted in and limited by an outer peripheral side surface of an end portion of the first connecting rod.

This eyewear system is provided with a first lens including an optical characteristic variation region in which an optical characteristic varies, a first frame for retaining the first lens, and a second frame for retaining a second lens different from the first lens, the first frame having a first attachment part for attaching the first frame to the second frame, or the second frame having a second attachment part for attaching the second frame to the first frame, so that the first lens and the second lens face each other and the optical characteristic variation region is positioned in the field of view of a subject through the second lens.

Provided is smart glasses including a spectacle frame having a lens frame to which a pair of lenses or a display is coupled and a pair of spectacle temples which extends from both ends of the lens frame in one direction; a cartridge detachably mounted on the spectacle frame and in which a functional material contained; a spray nozzle which is provided at a nose pad portion of the lens frame and discharges the functional material contained in the cartridge to an outside; and a supply path formed inside the spectacle frame to supply the functional material from the cartridge to the spray nozzle.

A wearable device includes a frame, two feet, and two pivoting modules. Each of the pivoting modules includes a first bracket fixedly connected to the frame, and a second bracket fixedly connected to one of the feet and pivotally coupled to the first bracket. The second bracket includes a positioning member and an inserting member. The positioning member is located in the first bracket, and the positioning member includes a plurality of slots. The inserting member is switchably inserted into one of the slots for adjusting a maximum outreaching volume from the frame to the feet.

Elastic hinge for eyeglass frames, which comprises an articulation screw engaged in the holes of two articulation elements. The articulation screw comprises a shank provided with a narrow portion, which is engaged in the hole of a first tab of an articulation element, and with an enlarged annular portion, which forms a step and is engaged in the hole of a head portion of the other articulation element. The articulation screw assumes an end stop position, in which it is tightened and aligned with the hinging axis, and a blocking position, in which it is loosened and is tilted with respect to the hinging axis in response to the elastic force exerted by an elastic device, such that the step of the articulation screw interferes with the edge of the hole of the first tab of the articulation element, preventing a further unscrewing of the articulation screw.

An eyewear device having a frame positionable to a removable engagement with any of a plurality of lens assemblies. Each lens assembly has shoulders at opposing ends which slidably engage within respective shoulder slots formed into the body of the frame. A biased ball having a portion extending into one or both shoulder slots, biasly contacts into a ball cavity depending into a respective shoulder to maintain the lens assembly in the removable engagement.

An eyeglass frame is disclosed comprising a bridge and two rims connected by the bridge. Each rim is configured to contain a lens. The eyeglass frame also comprises two split end pieces. Each split end piece comprises a first portion and a second portion. Each split end piece is coupled to and extends outward from a corresponding rim of the two rims on a side of the corresponding rim opposite the bridge. The eyeglass frame further comprises two temples. Each temple comprises a lock on an end of the temple. The lock is configured to at least partially contain both the first portion and the second portion of the split end piece and secure the temple to the corresponding rim and secure the lens within the corresponding rim.

Elastic hinge for the plastic frame of eyeglasses, which comprises a first articulation element and a second articulation element, wherein the first articulation element comprises a box-like body provided with a seat and a carriage provided with a rod-like element inserted in the seat and with a head externally projecting from the seat and coupled with the second articulation element. A bush is slidably mounted on the rod-like element, and a spring thrustingly acts on such bush. A fork-shaped body is inserted from the outside into a hole of the box-like body and is engaged with the bush in a straddling manner in order to retain the latter with respect to sliding along the longitudinal axis of the rod-like element.

Embodiments for systems, methods and apparatuses of eyewear are disclosed. One method includes treating a patient with shutter glasses therapy for a relatively short period of time, such as at least a 6 week period; wherein the shutter glasses therapy includes blanking a first lens of shutter glasses being worn by the patient for a first blocking time, blanking a second lens of the shutter glasses being worn by the patient for a second blocking time, and controllably setting at least one of the first blocking time and the second blocking time.

Elastic hinge for eyeglass frames, provided with two pivot elements hinged together by means of a pin. A first pivot element is provided with an elastic device comprising a carriage provided, at an external end thereof, with a head portion having a first hole which is extended passing between its two lateral faces. A second pivot element comprises two shoulders provided with second holes and delimiting a slit between them in which the head portion is inserted. The head portion comprises a tilted slide surface, which is extended towards the external end of the carriage on at least one of the lateral faces of the head portion directed towards the head of the pin, covering at least one area adjacent to the first through hole.
