title: [A new apparatus for testing binocular vision (author's transl)].
abstract: The Optometer can be used in a binocular manner if the loupe-lens is replaced by a concave mirror of appropriate size and form. The concave mirror or the plane mirror connected to it can be partially transparent. With an appropriate arrangement of these elements the test field can be seen in free space. The image can be adjusted from infinity to 35 cm by displacement of the test object. Choice of the test object makes possible testing the stereoscopic vision under natural conditions. Other test objects can be used to test further functions of the eyes-monocular, binocular or separately.
