Hello Edward,when you say that you had the CAA eye test what exactly do you mean?Did you go to Gatwick for it or did your own optician replicate the test as most opticians have a file detailing various visual requirements for different careers.If your optician did the test himself he and you may not yet be aware that the limits HAVE already been relaxed and now lie at -5D rather than the old -3D.This,however,may have certain age restrictions attatched to it and you would do well to contact the CAA medical folk at Gatwick who are most helpful.
Good Luck
