it has to be correctable (spelling?) to 20/20. My eyesight is 20/20 in one eye and 20/15 in the other so, no problem there. I just didn't want to be a pilot, but I still wanted to fly so my job fits me perfectly (since I like to tell ppl what to do! lol). I get to wear a flightsuit and I get wings, so I'm happy...lol
