Depth: Some individuals describe 3D as “popping off the screen” or “coming right at them”, while others only see a faintly raised image or a flat image that resembles a traditional screen. This lack or absence of depth is one of the signs that the binocular vision system is not functioning properly.Do we have 3D vision?
We are 3D creatures, living in a 3D world but our eyes can show us only two dimensions. The depth that we all think we can see is merely a trick that our brains have learned; a byproduct of evolution putting our eyes on the front of our faces. To prove this, close one eye and try to play tennis.Can all people see 3D?
