ABSTRACT:
A stereoscopic viewing device of the lorgnette type. The device may be fitted with accessories such as a hingedly mounted bridge member and adjustably mounted bow members. When positioned normal to the plane of the base member, the bridge member spaces the eyes of the viewer a predetermined distance from the base member and allows the viewer to hold the device with a minimum amount of instability. Bow members of the type used in spectacles, but having adjustable positions, are provided as an alternative to the standard handle member. An improved septum is provided by positioning base out prism lenses of the type formed from simple whole lenses such that the excess lensed aperture areas are eliminated and the need to frost or otherwise render opaque the nasal edges of the lenses is obviated.
