During my Class 1 recently the AME also mentioned that lying on the form is a severe infraction which could lead to loss of licence and privileges.
It was quite a scary thought.
The AME is a straight down the line chap and although the message was stern, it is likely from the CAA. Probably a campaign, perhaps after a spate of dishonest medical submissions that they want to crack down on.
Although I was able to read the bottom line of the eye test, he said I should also get my eyes tested, because if I failed the test next year, I could again be grounded until the issue is resolved and I would have to pay for a re-test.
So perhaps your AME lacks interpersonal skills, but there may be a CAA reason behind this.
