The Lang stereotest II-R is used for binocular diagnostics and screening of stereo vision disorders from as early as 6 months of age. In this revised version of the Lang stereotest II, quality has been improved both visually and in terms of printing. Due to the special combination of random dots and lenticular, no special glasses are needed and gaze patterns can be observed without restriction. On the back of the test card you will find a quick guide and the mirror image arrangement of the stereo objects with a typical pattern of eye movements in stereopositive patients. When used correctly, the test has no monocular clues. The Lang stereotest II-R works on the same principle for testing binocular vision as the Lang stereotest I-R. In addition to the three figures that are only visible binocularly (crescent moon, car and elephant), there is also a contrasted star on the test card that can only be seen with one eye. This monocularly visible star has a disparity of 200", which should improve the increase of attention and response in small children.
