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

I wear glasses, and if I swim with goggles, everything is blurry.

However, there are some interesting optical things that happen with the water. Between the reduced distance you can see and the funky stuff that refractive indices can do, I can understand it feeling like your vision is corrected.

I have a pet peeve about universalizing one’s personal experience. If I felt like my vision were corrected underwater, I wouldn’t assume everyone else’s was too.

OP, have you always been using corrective goggles without knowing?

Also air is not normally a liquid where most people live.
