For an FAA class 1 medical, you have to achieve 6/6 vision in each eye separately either with or without glasses. So I doubt that using the FAA route to get around things will help in your case.
In the UK CAA tests, you will not be subjected to reading numbers on the chart. If my memory is still sharp enough, you only do the letters reading at an actual 6 meters (not projected on a mirror or any computer device that makes it equate to 6 meter distance). One eye at 6/9 is the limit for class 1 medical. Amblyopia should not disqualify you for class 1 medical as long as you achieve 6/9 visual acuity in the amblyopic eye and the divergence/convergence is within limits.
The visual field test is done in a very conventional way. The eye specialist will hold a pen between his fingers and fully extend his arm to make the pen barely seen at the edge of your peripheral visual field at about 1 meter away while you look straight ahead of you. Then he will alternate between either shaking the pen lightly with his fingers or just keeping it stationary, and you have to tell him when it's either "moving" or "stationary". He will repeat the procedure several times at different angles around each eye separately. If you pass this one, you will be fine for the visual field test. If not, you will have to do a computer-based test (there are many different versions of it and I'm not sure which one they do use in the CAA).
I hope this helps somehow.
Good luck.
