A collapsible sunshade(50) includes a pair of support arms(54a, 54b). Disposed on outer ends of the support arms are a pair of ribs (62a, 62b). A fabric sheet (51) is disposed between the ribs to form a sunshade. The support arms include a pair of outwardly extending lever arms (58a, 58b). The ribs similarly include a pair of lever arms (64a and 64b). A pair of push rods (70a, 70b) extend between the lever arms of the support arms and the ribs. As the support arms are moved from a closed position in which they are substantially parallel to an open position in which they are substantially apart, the lever arms cause the ribs to extend outward thereby extending the shade. Preferably the sun shade is designed to be fitted on a collapsible headrest such that the combination of the collapsible shade and headrest can be easily stowed and transported by a user.

A retractable, partial eyeshield assembly is attached to a single eye sighting device attached to, for example, a video camera. The partial eyeshield assembly is constructed so that it covers a portion of the medial field of view of the user's nonsighting eye. The obstructed portion of the nonsighting eye's medial field of view corresponds to that portion of the sighting eye's that contains only the image transmitted through the single eye sighting device's sighting aperture. By obstructing the portion of the nonsighting eye's medial field of view, the corresponding field of view in the sighting eye dominates. The obstruction of the portion of the nonsighting eye's field of view is achieved without obstructing a substantial portion of the nonsighting eye's peripheral and medial fields of view.

A front body or plate for disposition in front of an arch wire is connected to a fork for disposition behind the arch wire by a crosstie forming a mounting that can be slid lengthwise of the arch wire to enable the fork to embrace the body of a tooth bracket behind the arch wire. A saddle projecting from the front body opposite the fork projects rearward to form a socket engageable with the arch wire by movement transversely of the arch wire. The prong of the fork nearer the rearward projection of the saddle may be shorter than the prong of the fork farther from the rearward projection to facilitate installation of the mounting.

A partial eyeshield is attached to a sighting device, for example a video camera. The eyeshield is constructed so that it covers a portion of the field of view of the user's nonsighting eye. That portion of the nonsighting eye's field of view corresponds to a portion of the field of view of the sighting eye the user desires to view without closing his nonsighting eye. So covering the nonsighting eye causes the corresponding field of view in the sighting eye to dominate, while leaving substantial usable vision through the nonsighting eye.
