A new product from the Swiss company LANG-STEREOTEST A.G., built on the same principle as known for years Lang I and Lang II tests.
It was designed to facilitate the study of spatial vision in children of all ages, even babies under 1 year of age.
It allows you to study general (global) stereopsy in the range from 1000 "to 50". It consists of 6 magnetic plates, each of which contains a spatial picture in the Random Dot technique. Each magnetic picture can be shown separately and placed on both sides of the red pad. Test images remain perfectly hidden if you observe them on one side or in the horizontal orientation of the lenticular mesh.
LANG-Stereopad is suitable for both stereopsis as well as preferential looking. In this second application, we use the rule of the forced choice task (with 2 or 3 options). You can also specify a stepwise stereopsy threshold.
The test does not allow guessing, it does not require any additional filters.
