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.

In an eyeglass retainer system for use with eyeglasses having a frame front that includes a pair of eyeglass temples, each temple has a first end for securing the temple to frame front and an opposite second end. Each temple defines an elongated channel passing therethrough and opening to the second end. Two cords are each disposed within the channel defined by a different one of the temples and extend out from the second end. Each chord is extendable from the channel and retractable into the channel. Two magnetic connectors are each affixed to a different one of the cords. The two magnetic connectors have opposite polarities so as to attract each other when placed against to each other. A stopping mechanism prevents the chord from exiting the hole completely.

An eyewear system having a lens and a nasion pad is disclosed. The nasion pad is configured to fit on a user's nasion and at least partially secure the eyewear in position. In one embodiment, the nasion pad has a saddle shape to prevent movement or rotation of the eyewear with respect to the user's face. A nose contact is coupled to the nasion pad. The nose contact can have a channel adapted to receive a leg extending from the lens. The lens is coupled to a retractor which provides a force to pull the lens toward the user's face. The eyewear system can be coupled to a helmet or hard hat. The lens is moveable between a first position on the user's face and a second position on the hard hat. The eyewear can be frameless and the retractor can be coupled to an engagement feature on the lens.

A device for retaining eyewear is disclosed. The device comprises one or more tethers rotatably coupled to a plurality of temple fasteners, the temple fasteners coupled to the temples of eyewear disposed on the ears of a user. More specifically, the device can further comprise a plurality of positioning members configured to couple with and rotate within a temple fastener to allow a tether coupled to the rotating position member to rotate relative to the head and neck of the user. The at least one tether can be disposed in various fixed positions relative to the head and neck of the user as well as relative to the eyewear.

In another embodiment, the guiding means is eliminated and the cables are connected by means of the grasping means.]. .Iadd.such that when the temple retainers are attached to the temples of a pair of eyeglasses and the eyeglasses are worn by a wearer, the resilient member forms an arc suspended off the wearer's neck.Iaddend..

Apparatus for connecting first and second eyewear ends. The apparatus may include a strap including a first strap end and a second strap end. The apparatus may also include a first connector at the first strap end. The apparatus may also include a second connector at the second strap end. The first and second connectors may include a first and second base, respectively, a first and second head, respectively, and a first shaft extending between the first base and the first head and a second shaft extending between the second base and the second head, respectively. The apparatus may also include a first fastener and a second fastener that may include a first attachment end and a second attachment end, respectively, and a first connection end and a second connection end, respectively.

Cloth tab with fastener sewn onto the back of headwear that serves to couple the headwear to eyeglasses straps. Either, or both, of the headwear or eyeglasses can be removed and they will hang from the tab and remain in proximity to the user without the user having to hold either item. The cloth tab is comprised of cloth and fastener such as Velcro snap, or button. The cloth tab is sewn onto the adjustment strap of headwear.

A slip-resistant eyewear system comprising an eyewear frame generally comprises a nosepiece comprising a nosepiece material configured to couple to a bridge of an eyewear frame. The frame comprises first and second hinges coupled to the eyewear frame which are also coupled to first and second spring-loaded tension adjusters. First and second bows are coupled to first and second tension adjusters. A unitary eyewear retainer comprises 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 eye glass retention system that includes an eyeglass frame comprising a lens frame and first and second temple arms attached at a proximal end to the lens frame at opposing ends of the lens frame. At least one of the first and second temple arms has a temple arm cavity extending lengthwise of at least a portion of the at least one temple arm with a distal opening proximate a distal end of the at least one temple arm. A central post resides within the temple arm cavity extending axially of the temple arm cavity with a space surrounding the central post between the central post and an interior wall of the temple arm cavity. A retention band has a first and a second end. At least one of the first and second ends has an opening into a retention band cavity defined by a retention band sidewall extending lengthwise of at least a portion of the retention band. The retention band is configured so that the inner surface of the sidewall contracts inward when subject to axial tension and expands outward when subject to axial compression. The central post within the temple arm cavity is received in the retention band cavity through the opening of the retention band cavity and the retention band sidewall is received in the space surrounding the central post.
