Lang-Stereotest® II-R complements the tried-and-tested Lang-Stereotest® I-R (star, cat, car) and is also used to test binocular vision on the same principle. In addition to three figures that can only be seen binocularly (crescent moon, car and elephant), there's also a profiled star that can be seen with just one eye. Many users had requested another stereoscopic test card as an alternative to Lang-Stereotest®I-R. In Lang-Stereotest® II-R, the random dots are smaller and less dense. The disparities are chosen to be slightly finer, 200 arc seconds for the moon, 400" for the car and 600" for the elephant, valid for an observation distance of 40 cm (10-15 inches). The monocularly visible star with a 200" disparity is said to improve diagnosis in young children by increasing attention and reaction. In addition, subjects without binocular vision remain less disappointed.
