Purpose Multiple functional disturbances related to disorder of the stereoscopic vision have been revealed by the development during these last few years of 3D on all kinds of screens. In order to understand and potentially predict the occurrence of this new symptoms, a platform for detection and qualification has been designed at 3‐D Fovea Observatory ‐ Brest (France) Methods ‐ This platform includes: • 3D 107 cm plasma screen • 3D active pair of glasses equipped with a LCD opturator specifically developed for the study (high blocker level > 1/1000 and contrast sensitivity C1 : 350‐400), • oculometer able to follow the visual strategy, • computer for the tests diffusion and collection of data ‐ We developed a first kit of 4 tests focused on the detection of capacities for 3D tolerance. The evaluated parameters are : stereo‐acuity, simultaneous perception, total fusion and hyper stereopsis. Results Outcome issued from these 4 tests can be expressed in different ways according to the competence level of the user. A simple colored scale for the general population and quantification for the ophthalmologist and the orthoptist. Mean time required for performing this first series of exams is 403 seconds +/‐ 93. An evaluation in a risky population for abnormal binocular vision is ongoing. Conclusion preliminary results seem encouraging and should allow an extrapolation to the quality of relief perception on a movie in 3D. The interest of this platform lies on its simplicity of use, its ability to predict the tolerance to 3D exposure and to offer new tools for a modern and dynamic evaluation of binocular vision.
