Well thanks for the comments.
Redsnail: Thanks, that is interesting. I am not cross-eyed so hopefully that will not be an issue.
openfly: The vision is only blurred for a short period with my left eye only. I guess diabetes would have been picked up at the class 1 urine test.
BoeingMEL: Sorry to hear that you have MS. I hope all is going well. Yes it is time to move on, ATPL theory time!
