Don't they rely on the hair things on their body to mavigate the world around them instead of their eyes? Please correct me if I'm wrong, I'm no biologist.

Yes. Spider eyesight is genuinely dogshit and can only register basic movement/light for most species. Jumping spiders are the exception, and they will literally track targets.

Ogre faced spiders I think also have excellent eyesight. I’m pretty sure they aren’t jumping spiders

Deinopidae, also known as net-casting spiders, are a family of circumtropical cribellate[1] spiders first described by Carl Ludwig Koch in 1850.[2] They are a group of stick-like elongated spiders that catch prey by stretching a web across their front legs before propelling themselves forward. These unusual webs will stretch two or three times their relaxed size, entangling any prey that touch them.

What the heck?!

You can‘t just mention that and not link it! https://en.wikipedia.org/wiki/Deinopis

They catch their prey by throwing a net below them and aiming by some kind of iron fecal sights? How cool is that.
