when i joined, post the changes in 1995, my eyes were myopia -1.0 in one eye and -0.75 in the other. I was worried through training about being thrown out at some point but once you are in they don't mind (I'm -1.5 in worst eye now). It seems I was outside limits on joining (myopia limit -0.75) but still got accepted so you never know (can't remeber my astigmatism limit at the time)! I know the RAF accept only perfect vision (because they get so many applicants they can afford to reject on eyesight alone) but i'm not sure on the limits for the army. If in doubt call Yeovilton or Culdrose Medical center, they'll be able to advise you.
