LANG-STEREOTEST I-R: A new chapter in glasses-free stereo screening

Entry from 2021/10/05
We are pleased to announce the availability of our new LANG-STEREOTEST I-R.

The successful LANG-STEREOTEST I has been extensively revised after almost 40 years and now bears the designation I-R (for revised). Thanks to modern technologies, the optical quality of the test cards has been improved compared to the original from 1982, resulting in a higher homogeneity of the dot pattern and reduced one-eyed detectability.

The tried and tested format and test motifs have been retained, but the CAR object has a cross-disparity of 400", which improves the gradation between objects. The new test features rounded corners and easy-to-follow instructions on the back. It comes in a lightweight and sturdy white case that is more compact and lighter than previous versions, with a total weight of only 54 grams.

We are convinced that the new LANG-STEREOTEST I-R is the modern and high-quality product that offers glasses-free stereo screening for all age groups in contemporary quality and optics.
