Caution: Risk of confusion with Lang Stereotest II

Entry from 2025/10/01

We are aware of a product that is marketed for the same purpose as the Lang- Stereotest II, in some cases even under the same name, but which has substantial quality issues. Its use leads to false positive results, meaning that reliable stereo screening cannot be guaranteed. When purchasing, please make sure to look for our logo, the Lang Stereotest® trademark on the back of the card, and the original test figures STAR, MOON, ELEPHANT and TRUCK, which are part of the main distinguishing features. If you have accidentally purchased such a product, please contact us.
