How come do we see neatly without correction under water?
When snorkeling, scuba diving, or just swimming with goggles, you don’t need corrective glass, why does water do this and not air? Both are transparent continuous fluids.
I don’t think that is some universal thing, because people do wear contact lenses or diving eyeglasses or prescription dive masks.
I think those are for people that normally need corrective lenses (e.g. glasses). Not something special for underwater specifically
EDIT: ah wait I see what the OP was saying… Yeah I don’t think water magically fixes vision problems
