ABSTRACT:
A binocular device wherein the two ocular lenses may be quickly focused entirely independently of one another. Rocker bars located between the bodies of the telescopes may be pivoted by the fingers to focus the respective lenses while the binocular device is held to the eyes in the normal manner. A rack and pinion mechanism for each rocker bar engages a slide pin which is connected with the ocular lens housing in order to move the lens housing toward and away from the corresponding objective lens as the rocker bar is pivoted in opposite directions.
