EJECT-
I am delighted to see that another idiot is shortly to join us on the flight deck!
Seriously, you have never flown on a commercial jet, and I can assure you that someones eyesight is the least of your worries.
Your eyesight does not go in an instant, it goes gradually over many months, so it really is not going to cause too many problems.
I agree that the CAA should allow it. I would remind you over a very serious incident on a 737 a couple of years ago when the Captains glasses fell off, and in his attempt to retrieve them nearly caused a major accident. All I am saying is that if your eyesight is within limits when you go for your class 1 medical, why give the authority the chance to refuse you a medical by opening your mouth.
One final point, how many commercial pilots do you know that trick the urine test at their medical by not eating or drinking for 24 hours before they go for their medical? There is a real danger here if the pilot is diabetic and does not know it.
