House Fly LEA Stereo Test

By spatial vision we mean the three-dimensional perception of space.

"The House Fly" Stereotest ( "Titmus-Test") is a simple way of testing stereoscopic perception in all age groups. Everybody, including small children, grasps what a fly is.

The glasses with polarized lenses used in the stereo vision test, "The House Fly" by VAC, polarize the light depending on the direction it comes from. For people with normal vision they create a spatial picture, while someone with impaired vision does not perceive it.
