LANG STEREOTEST® I-R
Intended use and main features
LANG-STEREOTESTS® are orthoptic products for binocular diagnostics and screening of
disorders of stereoscopic vision in adults and children, for medical professionals.
The LANG-STEREOTESTS® I-R (Ref 103) and II-R (Ref 104) are used for rapid screening of
stereopsis vision in all age groups from 6 months of age. Since loss of stereopsis is considered
a key symptom of amblyopia (lazy eye), failure to recognise random dot stereograms may
indicate a previously undetected, treatable disorder of binocularity (e.g., microstrabismus,
anisometropia). LANG-STEREOTESTS® have proven to be highly specific and highly sensitive
for stereo vision. Thanks to the unique combination of random dots and a lenticular lens, no
special glasses are needed, and the eye movements of the subject may be easily observed.3D Objects and Disparities
