Abstract

A binocular stereoscopic viewing device for examining an eye having a light source and a first light guide for directing light from the light source to the eye to be illuminated. A second light guide redirects light representing the stereoscopic image of the eye. A support mechanism supports both the first light guide and second light guide and is operable for moving in directions towards and away from the eye. A tilting mechanism repositions the first light guide relative to the second light guide for varying the angle at which light from the light source is directed by the first light guide toward the eye to be illuminated.
