When I went a couple of years ago, the optician said "it's just age. you just need reading glasses" but it's a pity age does it to everybody whether they are used to wearing glasses or not. I am probably at the point where I need more than reading glasses but I don't have stereo vision anyway and when wearing my reading glasses, I find I tend to keep one eye shut, and I feel dizzy if I move my head when wearing them so I'm not sure I could cope! I need a magnifying monocle like Lord Peter Wimsey.
