LANG-STEREOTEST^® I-R

The Lang-Stereotest^® I-R is a 2021 revised version of the Lang-Stereotest^® I, which was developed by J. Lang for binocular diagnostics, especially for screening stereo vision disorders. This revised version has improved optical and print quality compared to the earlier version and has no monocular clues when used correctly.

LANG-STEREOTEST^® II-R

The Lang-Stereotest^® II-R is a 2023 revised version of the Lang-Stereotest^® II, which was developed by J. Lang for binocular diagnostics, especially for screening stereo vision disorders. This revised version has improved optical and print quality compared to the earlier version and has no monocular clues when used correctly.

The Lang-Stereotest^® II-R is a supplement to the proven Lang-Stereotest^® I-R (star, cat, car) and is also used to test binocular vision according to the same principle.

LANG STEREOPAD^®

With the LANG-STEREOPAD^® - analogous to the proven LANG-STEREOTEST^® I-R and II - random dots are combined with a cylindrical grid surface. However, the spectacle-free test offers more differentiated possibilities for screening and testing stereopsis, especially also in children of pre-verbal age, with the Preferential-Looking Method. In addition, it can be used to determine the stereopsis threshold.

Magnetic support for LANG-STEREOPAD^®

The single-leg magnetic support was specially developed for the Lang-Stereopad^® and is an optional accessory. It allows the test plate to be placed on a table at an angle in reading position.

LANG fixation cube white/red

The LANG FIXATION CUBE were developed by J. Lang for the assessment of eye fixation, motility, accommodation, convergence, for the cover test and for preparation for the Lang-Stereotest^® or Lang-Stereopad^®.

Each rotation shows a different object. The star on the top and the other images can also be used to test convergence.

LANG fixation sticks

The LANG FIXATION STICK was developed by J. Lang for the assessment of eye fixation, motility, accommodation, convergence, for the cover test and to prepare the patient for testing with the Lang-Stereotest^® or the Lang-Stereopad^®.

LANG-STEREOTEST^® I (first edition until 2020)

The Lang-Stereotest^® I was replaced in 2021 by the new improved edition Lang-Stereotest^® I-R.

LANG-STEREOTEST^® II (first edition)

The Lang stereotest^® II was completed in 2023 by the new improved version Lang-Stereotest^® II-R, but is still availabe.
