LANG STEREOTEST

LANG-Stereotest AG is a Swiss manufacturer specializing in diagnostic devices for screening stereoscopic and binocular vision. Based in Küsnacht near Zurich, the company has been developing stereo vision tests for professional use by ophthalmologists, orthoptists, optometrists, and opticians since the 1980s.

The brand’s foundation lies in the work of Joseph Lang, who introduced an innovative method for stereo vision screening without the use of test glasses. The combination of random-dot stereograms and lenticular technology allows for fast, reliable, and patient-friendly testing, even for young children.

LANG Stereotests

LANG’s product range includes the LANG Stereotest I-R, LANG Stereotest II-R, and the LANG Stereopad. These products are used worldwide for the early detection of binocular vision disorders such as amblyopia and microstrabismus. All tests are designed for clinical reliability, ease of use, and compliance with applicable European regulations for medical devices.

As an official distributor, we supply high-quality LANG tests.
