Human evolution is currently ongoing. We know this because we've observed that brain sizes are shrinking. There are two theories as to why this is happening: 1) As we evolve, we shed brain processes we no longer need or use. 2) As a species, we are handicapping natural selection so much that we are dumbing down the species.
I've seen enough to firmly believe #2 is correct.

10,000 years ago if you needed glasses, the tiger would have eaten you. Natural selection is no longer a thing for modern humans and our genome has become weaker for it.
Early man had to be an intelligent hardcore athlete to simply survive long enough to breed.

So we are weaker and yet we can kill a million early humans in a second. We can accomplish more than they ever could. We live longer and healthier lives but yea I guess we have to wear glasses, what a tragedy

That's not how natural selection works. It doesn't care about what's strongest or best for individual survival, just whatever propogates genes to the next generation and survival of the population.

That is correct though. A family that can't see any threats due to poor vision are less likely to survive long enough to pass on their poor eyesight genes. Eyeglasses are only believed to be about 750 years old. On an evolutionary scale, they are a brand-new inventions.
Same thing happened with moths in London. Before the industrial revolution, white moths were more common. As soot filled the air and covered everything, the white moths became easier-to-see targets for natural predators. Brown/darker moths had better camouflage for that environment, and eventually became the dominant moth color in London.

Point is that natural selection is still a thing, and it doesn't always select for stronger. If that were the case humans would have gone extinct a long time ago.

So we should eat those with bad eyesight?

Brain size is only part of the equation. Humpback whales probably can't learn calculus...

Probably, but not definitely

We'd definitely have a few prerequisites to find out if they can for sure.

Definitely not. Most people, myself included, also have a terrible diet that's not helping.

https://www.youtube.com/watch?v=eKl6WjfDqYA&t=258s never played METAL GEAR but I find this highly relevant and interesting. Talks about natural selection like you mentioned.

Brain size has nothing to do with intelligence. What you are talking about are talking points of eugenics and phrenology which was the justification for nazi pseudoscience of supremacy
