Lang Stereo Test I and II

Lang Stereo Test - For children - No polarizing glasses necessary

The Lang Stereotest is an easy-to-use screening-test designed for early detection of problems with stereoscopic vision in children. The 3D test objects appear each on a different level. Seen with only one eye (monocular vision), these stereograms do not show any shapes, while, upon binocular inspection, the figures, typically in different depths, can be seen. Using distance: 30-40 cm
