So, the last few years I always doubted my eyes for Class 1 standard as I have Amblyopia in my left eye. I finally scratched that itch and went for a standalone eye appointment with Adrian Chorley at Heathrow Medical.
I must say he was fantastic, answered so many of my questions and the eye examination is really just genrally interesting.
Anyway, I passed. Morale of the story - don't be put off and speak to an expert. There's always hope.
