Why haven't our eyes evolved to be able to look at the sun?

what exactly is your proposed evolutional fix

its hard to go blind from that unless you're actually retarded

it hurts as all fuck when you try so you cant do it long enough to cause damage, i've tried many many times when i was a dumb kid and it had no effect on my eyesight

>Imagine how many of our ancestors have gone blind looking at the great fireball in the sky.
Obviously very few, the pain is a good negater it would seem. Otherwise we'd probably have deeper eye sockets or something.

We've got no airborne predators so our species is primed mostly to look forward. Also, presumably most of us aren't retarded enough to stare at the sun.

They have. If you try, you will reflexively look away. Therefore they have evolved to not look at the sun. Its essentially the same thing as evolving to look at the sun since looking at the sun is a useless advantage.

Its like asking why we havnt evolved to breath underwater when in fact we have evolved to not breath underwater.

You should check your evolutionary privilege.

because it was ultimately more effective and attainable to evolve blink and pupillary light reflexes and an autonomic response to light overexposure that makes looking at the sun intensely uncomfortable than specialized dark yet transparent secondary lids that would only be useful for observing very bright lights which tends not to be advantageous in a biological fitness sense of the word. if any such individuals existed in the hominid family tree they were out-competed by rivals with more worldly concerns than staring at the sun.
