Simon OK, thanks. Trouble is that there is some interesting stuff posted on platforms either hosted by reprobates or occupied by reprobates. Bit of a pain, really. You have to wade through loads of rubbish in order to find the occasional bit of gold. I don’t have the time or inclination to wade!
The stroke caused my right eye to droop by about 4 degrees. The superb optitian has fixed this using optical methods and it is impossible to notice it. However, my vision is a little slow to adjust and, because it is muscular in origin, I have been looking for tested ideas regarding exercises. Indeed, I don’t know if they exist or are wise to do anyway.
