  • Patent number: 8913318
    Abstract: In an ocular support assembly material present in the forward-looking cross-section of the outwardly extending support arms is removed, thereby reducing visual obscuration and enhancing peripheral vision. In the preferred embodiment, the top of each outwardly extending support arm is at or below the middle of the height of the housing, thereby resulting in a low-profile design. At the same time, the support arms are received by the housing with sliding engagement on all sides, thereby eliminating the need for ball bearings or spacers to counteract twisting. The result is a lightweight yet highly stable ocular mounting assembly.

  • Patent number: 6493136
    Abstract: An optical accessory of the type used by medical professionals is coupled to a clip-on mount, enabling the assembly to be used with ordinary eyeglass frames. The assembly may be used with specialized frames, in which case the clip-on mount may be removed for a more permanent mounting of the assembly directly to the bridge area of the eyeglass frames. In different implementations, optical accessories in the form of ocular loupes, head lamps, and miniaturized video cameras may be accommodated according to the invention.

  • Patent number: 6439714
    Abstract: An adjusting device for use with a pair of telescopic oculars allows independent rotation of each ocular to correct vertical misalignment between the lines of sight of the oculars. The oculars are part of an optical mounting assembly that includes a housing in which two slide bars are mounted. The oculars are mounted on the slide bars through bosses and mounting screws. An adjusting set screw is threaded through a hole on each slide bar so that it can push against the boss. By tightening or loosening the set screw, the line of sight of each ocular can be adjusted vertically, so that vertical misalignment between the lines of sight is effectively controlled.

  • Patent number: 6340228
    Abstract: A formable nose pad distributes the weight of eyeglasses and accessories supported by the eyeglass frames over a large area of the wearer's nose. The nose pad has two inner tabs that can be formed to fit the wearer's nose, outer tabs that can be formed to fit the undersides of the eyeglass lenses and a flange through which the nose pad is attached to the eyeglass bridge. Slotted screw holes on the flange allow for height adjustment to fit the height of the wearer's nose.
