The new and revised Lang II-R Stereo Test is an easy to use screening test designed for the early detection of problems with stereoscopic vision in children and adults without the need for dissociating glasses.

In comparison to the original version, the optical quality of the test cards of the new Lang II-R Stereo Test has been significantly improved, the sharpness of the motifs as well as the homogeneity of the dot pattern has been increased and the single-eye recognition reduced.

It is suitable for children as young as 30 months by identifying pictures on a card. The test is simple, quick to use and fun for the child.

The Lang II Stereo Test measures from 600 to 200 seconds of arc. Each card shows three objects (elephant, car, moon) to be recognised which assess three different levels of stereo acuity. It also contains a star in addition that can be seen with only one eye.
