Aging makes you more nearsighted allegedly. Maybe if she lives long enough it will cancel out.
That is actually backwards. As you age you develop presbyopia which is an inability of the eye to adjust focus to near objects, so as you age you actually become more far-sighted. That's why older folks (even those with perfect vision) have to wear reading glasses.
I had Lasik in 1998 and I've been happy with it, but I still have to wear reading glasses because of my presbyopia. Also, as I age it turns out that my corneas tend to (as my opthamologist put it) sag which has led to developing some astigmatism.
I now wear progressive bifocals to read and for computer work, but I'm just fine without glasses for distant vision. Before lasik I was very near-sighted.
