Abstract
An improved spectacle frame for use with a telemicroscope or similar optical instrument. The spectacle frame includes temple pieces which are angularly disposed with respect to the lenses mounted in the spectacle frame, nose pads which extend toward the tip of the user's nose, rather than the eyes, and a uniquely designed, elevated bridge assembly. Optionally, a second pair of conventionally mounted nose pads may be provided. These features combine to achieve a more favorable positioning of the telemicroscope with respect to both the lenses of the spectacles and the eyes of the user, both to maximize the field of view and to improve the pantoscopic angle, and also improve weight distribution to minimize chafing, soreness and fatigue.
