Stephanie, I put off going for an eye test for a long time because of the expense, but when I felt I really dare not leave it any longer I had it done at my local Asda a couple of weeks ago. I had a very thorough eye test and their prices are very reasonable (e.g. £80 for varifocals). If you just Google Asda Opticians you can get all the info.

Hope your eye problem is soon sorted Carol. I too have a dodgy optic nerve which was discovered during an eye test many years ago, I think they said it enters the eye at an odd angle and they couldn't figure out what was going on.  Anyway, I was referred to the local Eye Clinic for it to be checked out, but they didn't seem to think it was a problem so I hope you are as lucky and that life soon takes a turn for the better.
