Abstract: An ANVIS 6 type of binocular night vision device includes a pair of night vision monocular scopes which adjustably depend from a support frame in front of a user's eyes. The support frame includes an interpupillary distance adjustment mechanism which allows placement of the monocular scopes to better achieve binocular vision with depth perception. The image quality of binocular vision afforded by the device is improved and made more durable by providing the monocular scope mounts with a dirt-shedding dry threaded engagement with their respective interpupillary adjustment shafts, as well as providing a laterally extended threaded engagement of these mounts with the adjustment shafts. As a result, wobble of the monocular scope mounts relative to the frame is significantly reduced, and wear of the component parts which over time contributes to increased wobble is also reduced.

The nose piece is connected to a push-push mechanism which is arranged so that a wearer, with the nose piece resting on his nose, can conveniently move the lenses up and down between a normal position and raised a position where the lower reading portions of the lenses are in front of the eyes by simply applying a momentary downward force on the bridge, the rims or the temple pieces.

Abstract: The goggles have two eyepieces connected by an elastomeric strap forming a nosepiece, the length of which is adjustable by loosening a pair of adjustment screws. Each eyepiece has an upper contour portion having a smooth incurve to conform to the upper eye socket. The lower portion of each eyepiece has a smooth incurve with an excurvation in the vicinity of the nosepiece to conform to the lower eye socket. Each eyepiece flares outwardly to form a widened eye socket contacting surface. Each of these surfaces slopes radially outward of the eyepiece and toward the front thereof. In this manner, when worn, the surfaces produce a radially outward pressure on the eye socket and require only a minimum layer of form padding to insure a watertight seal. The goggles are also equipped with an elastic head strap attached to a plastic hook end which fits into an aperture on one of the eyepieces for easy attachment thereto.

Abstract: To promote comfort and customized fitting of spectacles on individual wearers, an adjustable nosepiece formed of a thermoplastic is assembled with a nosepiece suspension frame by the optometrist after customizing the suspension frame for securement to either metal or plastic frame spectacles.
