THanks for answering everyone. The reason I asked the question is because I am having some problems with my eyes. I don't have an actual dx but he opth. said I have all the symptoms of an MS eye, but my optic never and eyes in general a very healthy. I think the poblems I am having at the moment might be because of a recent bout of shingles, it was on my eyelid and farhead. Its better now and the dr. said it did not go into my eye, but every little pain makes me nervous. I know shingles in the eye can cause loss of vision.
