My vision is excellent, and it's amazing it is actually.
I suffer migraines. There's a good source of screwed up vision.
I had the muscles operated on three times as a kid, I can still see in opposing directions when I relax my eyes enough though.
I tend to have lack of focus occasionally from all of this.
Think binoculars where each side is being adjusted independently, not simultaneously
Wore glasses as a kid, don't recall why.
In bright light, I almost always have one eye closed, a reflex I seem unable to stop, barely notice it actually. Probably should wear sunglasses more.
But on a whole, I can generally distinguish detail most can't see at all.
Many years as a modeller.
My eyes are one of the few things I am still able to count on over all.
