CA 2081329

2081329 9117465 PCTABS00008 A lens system comprises two magnifiers and distance measuring means. With the distance measuring means the distance is measured of an object to be viewed. The focal distance of the magnifiers is automatically adapted to the measured object distance while the convergence distance of the magnifiers is likewise automatically adapted to the measured object distance. This enables the user to automatically have a stereoscopically sharp view over a wide range of object distances, a magnification being obtained depending on the magnifiers employed.
