During the time I've had ME/CFS I've had constant sore, gritty eyes, night glare problems and stabbing pain behind the eyes (mini migraines as I think of them). But until recently my eyesight has always been excellent and tested at 100%. Since the last downward sprial that put me out of work though, my near eyesight has deteriorated badly to the extent that I now need reading glasses. This shouldn't be at all unusual as I'm now pushing 50. But. I'd assumed the problem was the usual blurring of vision due to age, but working at close quarters on something I discovered that I was actually seeing two perfectly clear images. A little googling suggests this is a common symptom with ME/CFS although relatively new for me and I'm only aware of it close up. Does anyone have the same problem and had their eyes tested (I haven't been tested in about 7 years)?
