There are many stereoscopic/depth perception tests on the market; some are geared more for children while others to adults. Many of these tests ask the patient to identify... This is accomplished by the arrangement of vivid (saturated) colored discs. If the average score is 1 or less, the FALANT is passed. For accurate depth perception, you generally need to have binocular (two-eyed) vision. My application process was almost complete. Stereopsis, also known as stereoscopic depth perception, is the ability of both eyes to see the same object as one image and to create a perception of depth.It is a measure of binocular visual function, i.e. To test validity the Stereo Fly Test (SFT) specifically the nine Stereotest Circles (SC; see Figure 1) was used on a subgroup of 81 partici - This simple online test will help you determine whether you have fully functional depth perception (AKA stereoscopic vision, binocular vision, 3-D vision ).
