Thanks Charleygirl. Sadly we have been down this route before as he had a stroke and post stroke fit seven years ago. He has to be fit free for a year, which is up in September, this is providing that he passes the field of vision test. His last stroke was in the occipital lobe which affects eyesight, but we are hopeful that his vision has recovered enough. Time will tell.
