Knock on wood, my vision's excellent! I do need to get reading glasses though, as I'm starting to have trouble reading. I can usually spot a street sign way before my husband even knows there's a sign. No problems with long distance vision, that's for sure. I've heard the comment many times that I've got bionic vision, or Xray vision LOL! I'm getting up there in age though, so don't expect this to last forever.... darn!
