Why are lenses still round then? Just for looks?

Because you can't focus an image with a square lens without getting ridiculous artifacts.

Lenses are round because evolution decided mammals should be able to see more of their surroundings.

It's easier to manufacture that way. You could cut the lenses to have square edges. The curvature would still have to be "round" though. You'll notice that some cameras have a square mask around the lens to reduce stray light.
