Eyewear for releasably receiving a lens has a joint sleeve for holding the lens in place.

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 system for mounting an eyewear lens on a user. The system includes a pair of nasal appliques, a bridge member, and a pair of lateral compression elements, with the bridge member and compression elements being attachable to an eyewear lens. The bridge member is magnetically engageable to the nasal appliques to limit translatable movement of the lens relative to the user, while the compression elements compress against opposed sides of the users head to mitigate pivotal movement of the lens relative to the user.

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.

Generally, the invention involves a post-operative care system configured to lift an eyewear frame away from the face, and more specifically, away from the nose. The system may include glasses having one or more extending legs that protrude away from each lens rim of the eyewear frame and have a length substantially perpendicular to each lens of the eyewear frame. In some embodiments, the leg is integral with the eyewear frame. In exemplary embodiments, each leg is removable from the eyewear frame and includes a first terminal end that receives a portion of the rim of each lens of the frame, and a second terminal end having a flat support surface configured to rest substantially flat against a portion of the wearer's face, such as against a portion of the wearer's cheek bone. In some exemplary embodiments, a length of the leg of the device is adjustable.

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.

The present disclosure relates to a mounting tool that makes it possible to sense the position or the orientation of the head in a natural state without impairing the wearing feeling or the appearance. The nose pad of the glasses comes into contact with and fixes the nose, which is the frontal region of the user, an ear hook including an insertion portion that allows the temple of the glasses to be inserted and fixed comes into contact with and fixes an ear, the occipital region fixing unit configured integrally with the ear hook comes into contact with and fixes the occipital region while holding the sensor device that detects the position and the orientation of the head of the user, the occipital region upper portion fixing unit comes into contact with and fixes the occipital region, an insertion portion that allows the temple of the glasses to be inserted is provided, and the occipital region upper portion is fixed. The present disclosure can be applied to motion capture.

A head-mounted display device includes an image display unit (300a, 300b) configured to emit image light, a light guide member (100a, 100b) configured to guide the image light and emit the image light to eyes of a wearer who wears the head-mounted display device, and a relay optical system (201a, 201b) arranged between the image display unit and the light guide member, and configured to relay the image light from the image display unit to the light guide member, and form an intermediate image at least once before the image light enters the light guide member.
