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 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
