Telescopic spectacles
First Claim
1. Telescopic surgical spectacles comprising:
- a frame;
right and left eye prescription lenses set in said frame, each said lens having a bore there through; and
right and left eye telescopes having focal planes for a common view point in the range of 8 inches to 30 inches, each said telescope disposed in the bore of each said lens;
the bore in each said lens being located at a customized point in each said lens such the bore center lies on a line from a respective eye to the common view point;
each said telescope being fixed in each bore with a central optical axis of each said telescope aligned and coextensive with the line from each eye of a user to the common viewpoint.

Abstract
A pair of telescopic spectacles includes a frame having a top bar and a bottom rim disposed to provide an aperture and a lens having a bore therein disposed in the aperture of the frame. The telescopic spectacles further include a telescope assembly disposed through the bore of the lens at a predetermined convergence and declination angle. The telescope assembly includes a first housing having a first aperture, a first region with a bore therein and a second region having a cavity therein, a second aperture and a first surface. The telescope assembly further includes a lens retainer disposed in the first aperture of the first housing, and an eyepiece assembly disposed in the first region of the first housing. The eyepiece assembly includes a lens housing having a first end with a first aperture and having a second opposing end with a second aperture. A first lens is disposed in the first aperture of the lens housing, a second lens is disposed in the second aperture of the lens housing a predetermined distance from the first lens. The telescope assembly further includes a prism, disposed in the second region of the first housing with a first surface of the prism spaced a predetermined distance from the eyepiece assembly. The telescope assembly further includes a second housing having a third lens disposed therein with a first surface of the third lens spaced a predetermined distance from a first surface of the prism.
