Hear, hear!
That's a different problem, we're talking eyesight here.
I have Amblyopia, did correction as a kid and the doc gets me to 20:40 or a little better. I once took the eye test for a drivers license and I read half the letters and the lady said, "how about the other eye?" I said, "nothing there!" she said, "yes there is" I closed my good eye and there it was. I won't repeat that next time.
Strangely, the optometrist removed a full diopter from my contact lenses prescription for that eye at my last appointment. If I keep that up, in 20 years I won't need contacts. eh, probably won't need them either way.
