>Simple answer: We never had to be able to do that for survival.
>Longer answer
Our eyes are designed to see the world in 3D: they are constantly adjusting and soaking up data to tell your brain what’s going on around you. This is why your eyes strain after looking at your TV for too long: your eyes are trying to picture a world in 3D…on a 2D surface.
Evolution tells us that the human eye found no reason to make eyes complex enough to see stuff that’s really far away. This is why hawks and eagles have excellent eyesight.
