A pair of eyeglasses includes a front with two lenses installed in the two openings thereof. Two lugs respectively extend from two ends of the front and each have a slot communicating with the opening corresponding thereto. Two threaded holes are respectively defined through the two ends of the front and communicate with the two slots. Two screws threadedly extend through the two threaded holes to narrow the slots to secure the two lenses in the front. The two lugs are clamped between the two connectors and two securing members by bolts extending through the securing members, the lugs and the two connectors, and connected with two positioning members. The lenses can be replaced by unscrewing the bolts and the screws.

The present invention relates to an extension and strap for eyeglasses. More particularly, the present invention relates to an apparatus for holding eyeglasses onto a user's face that allows for eyeglasses to be put on and removed with only one hand. The present invention also includes a method of using the strap of the present invention to put on, retain in place, and remove eyeglasses using only one hand.

A slip-resistant eyewear system comprising an angular adjustment screw configured to couple to a first hinge of an eyewear frame such that an angle of the eyewear frame is adjustable relative to a first bow and a unitary 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.

An eyewear retention device is disclosed that includes a length of resilient braided or monofilament line, terminating at each end in a tapered, rubberized retention tubing. One or more retractable spring loaded mechanisms have a locking mechanism for easy extraction and retraction back and forth by simply pulling on said line. The combination of the resilient line and the mechanisms produces a tensioned arc such that in addition to retaining eyeglasses around wearers head when in use when not in use with a simple pull on said line, the retention device forms a suspended arc over the wear's upper torso such that the device does not contact the wear's upper torso or their vestment when donned over a wearer's eyes.

Systems, apparatuses, and methods are taught that provide reconfigurable components for eyewear devices. A reconfigurable component for use in an eyewear device, includes a first temple. The first temple is configured for use with the eyewear device. The first temple further includes a first engagement portion. The first temple includes a first temple insert module (TIM). The first temple insert module is releasably couplable with the first engagement portion. The reconfigurable component can include at least one of a sensor and a display. The first temple insert module further includes a first wireless communication system. The first wireless communication system is configured to communicate wirelessly with a user device. The first temple insert module further includes a processor and a first speaker. The processor is configured to receive an input from at least one of the sensor and the first wireless communication system and to generate an output. At least one of the first speaker and the display are configured to receive the output. In operation, when a user wears the eyewear device the user can hear audio broadcast from the first speaker when the first wireless communication system is in an on state and may see an image with the display.

Eyewear in the form of a pair of lenses and a pair of frame halves, each frame half supporting a lens. The frame halves are releasably connected to one another at the bridge between the lenses at their inner ends and the frame halves have frame half outer ends on opposite sides of said lenses from the bridge. The eyewear also includes first and second temples having temple first ends and temple second ends, the temple first ends being pivotally connected to the frame halves outer ends, each temple including a channel. The eyewear also includes a flexible strap having first and second flexible strap ends, to which are affixed first and second sliders, each slider affixed to one end of the flexible strap at the first and second flexible strap ends. The first slider is located within the channel of the first temple and sized to be slidably positioned along the channel of the first temple and the second slider is located within the channel of the second temple and sized to be adjustably positioned along the channel of the second temple such that movement of the sliders enables a user to selectively change the length of the flexible strap extending between the second ends of the first and second temples.

Examples are disclosed for a customizable multi-purpose accessory that holds eyewear and provides for a removable add-on component. In one example, a customizable multi-purpose accessory device includes a housing, a magnet, a spool having a top surface facing a top inner surface of the housing, the magnet being disposed between the top surface of the spool and the top inner surface of the housing, and a retractable cord. The customizable multi-purpose accessory device may also include a torsion spring positioned in a central bore of the spool.

A system is provided to secure a pair of glasses to a hat, the system including a hatband insert configured to be inserted in a hatband of a hat, one or more hatband magnetic members configured to be selectively attachable to a plurality of locations of the hatband insert, and one or more glasses magnetic members configured to be attached to each temple of a pair of glasses, wherein the one or more hatband magnetic members and the one or more glasses magnetic members are configured to be magnetically attached to selectively secure the glasses to the hat.

An adjustable eyewear restraint comprises a first strap having a first adjustment end and a first eyewear coupling end, and a second strap having a second adjustment end and a second eyewear coupling end. The straps are slidably and frictionally engageable to one another to allow adjustment of a length of the restraint by moving adjustment ends of the straps relative to each other. The straps can be slidably interwoven to each other about opening(s) of respective adjustment ends. The opening(s) slidably receive an opposing strap. A strap has a loop, coupleable to eyewear, that comprises first and second edges attached together to form an attachment portion substantially in-line with the first edge. A frictional element is frictionally and slidably coupleable to an earpiece to retain the loop and allow adjustment of a length of an eyewear retainer. Associated systems and methods are provided.
