The Lang Stereo Test is an easy to use screening test designed for early detection of problems with stereoscopic vision in children and adults without the need for dissociating glasses.
Two versions are available which differ only according to the 3D objects to be recognised. Each test assesses three levels of stereo acuity on one handy card. The Lang Stereo Test 2 contains a star in addition that can be seen with only one eye.
Please note that this stereo test does not measure visual acuity and does not substitute for an ophthalmologic examination.
