A harness apparatus for use with a head-mounted display device is disclosed. In at least one embodiment, the apparatus provides a pair of display connector portions positioned on opposing left and right sides of the display device. A harness assembly provides at least one elongate primary head strap for engagement about a user's head, with opposing terminal ends of the at least one primary head strap being positioned proximal a left temple and a right temple, respectively, of the user's head, and providing a pair of strap connector portions configured for removable engagement with the pair of display connector portions. The harness assembly further provides a gasket extending between the strap connector portions and configured for being positionable in contact with a face of the user so as to be sandwiched between the display device and the user's face when the display device is engaged with the harness assembly.

A harness assembly provides at least one elongate primary head strap for engagement about a user’s head, with opposing terminal ends of the at least one primary head strap being positioned proximal a left temple and a right temple, respectively, of the user’s head, and providing a pair of strap connector portions configured for removable engagement with the pair of display connector portions. The harness assembly further provides a gasket extending between the strap connector portions and configured for being positionable in contact with a face of the user so as to be sandwiched between the display device and the user’s face when the display device is engaged with the harness assembly.

A head-mounted fixing device includes a head frame, a bracket and a headband. Two side frame portions of the head frame abut against two sides of a user’s head, and a front frame portion of the head frame is located between the two side frame portions and abuts against the users' forehead. The headband is movably connected to two first adjusting members of the head frame, so the position of the front frame portion on the forehead can be adjusted by adjusting positions of the two first adjusting members on the headband. The bracket abuts against the top of the head. The headband can wrap around and abut against the back of the head. The head frame, the bracket and the headband abut against the head to restrict the head-mounted fixing device from moving relative to the head, so that the head-mounted fixing device may be worn without shaking.

Optical bridges including a bridge body configured to be mounted directly or indirectly onto a head-worn device and at least one rail operatively engaged with the bridge body, in which the at least one rail having a first end and a second end. The optical bridges also include a first stopblock located at or proximate to the first end and a second stopblock located at or proximate to the second end. The at least one rail has a first side portion located between the first stopblock and the bridge body and a second side portion located between the second stopblock and the bridge body. Systems including an optical bridge and one or more optical devices directly or indirectly releasably coupled to the optical bridge are also provided.

The EZ Mirror has a mirror system connected to a mirror vest by way of a flexible conduit. The mirror system has a central mirror between a left mirror and a right mirror. The left mirror is connected to the central mirror at a left mirror angle and the right mirror is connected to the central mirror at a right mirror angle. In use, the mirror system is held in place behind a user's head by the flexible conduit and mirror vest worn by a user, enabling the user to use both hands while looking into the mirror system of the EZ Mirror when engaged in activities such as cutting or braiding one's hair. The EZ Mirror allows a full view of the sides and back of a user's head without having to move any mirror in the mirror system.
