Do we SEE in 3D or is our Space 3D? To see things in 4D do you need 4D eyes for 4D space?

The back of our eyes have screens on them screens that gather up the light going into the eyeball (this is how our vision works). These screens are flat. So each eye is 2D. But since both of the eyes are at a different position, our brain can take those two flat pictures and figure out what the 3D world looks like. This usually works, but since it is guessing a bit, sometimes we make mistakes–this is how a lot of optical illusions work.
