I think the requirements for the RAF were similar.
Note that this was three or four years ago, and I can't remember all the details.
If you're interested in joining, call or visit a Careers Office and ask!
Ok, but 6/60 (20/200) is about 2 diopters, so it doesnt make sense that they will allow up to 5 diopters.
