Can someone please explain what the eye test for the medical involves - how perfect does your vision need to be (and if you wear glasses or the optometrist says you need to wear glasses), do you fail? I have just been prescribed glasses for computer work, as the bright computer I use for my day job (8 hours a day) has been making things blurry by the end of the day. In the mornings and on weekends my vision is fine so I feel it's just the computer making things blurry, so I wouldn't need to wear glasses while flying (or at all if I changed jobs - I feel my vision is otherwise completely fine). Do you think this will be a problem?
