New Study Confirms Validity of the Lang-Stereotests I-R and II-R

Entry from 2025/10/28

A recent study by Sigrid Entacher, Anja Brunnauer, and Ruth E. Resch (FH Salzburg) confirms the validity of the new Lang-Stereotests I-R and II-R in adults with normal vision and demonstrates clear advantages over the previous versions.
The updated tests feature enhanced optical quality and a modern design.
Thanks to their glasses-free format, Lang-Stereotests remain ideally suited for early stereopsis screening in children as well as for assessing binocular vision in adults.
