We rely pretty heavily on 'synthetic aperture' reconstruction. Close one eye, look at a scene with objects at various distances. It looks flat - near and far are hard to distinguish. Move your head right and left (still one eye closed) - the objects jump out at you, nearer ones clearly 'in front' of further ones.

So the 2D retina is just the start - our neural processing jelly is reconstructing a 3D image from it continuously. This affects how we perceive the world drastically. Lots of room to fool the algorithms. Not because the hardware (eye/retina) is faulty; because using fairly simple and efficient hardware, our incredible neural processing elicits tremendous results!
