I have been having the same eye problem for several months. I am on a computer ALOT for work. I went to the eye doctor and got glasses for Farsightedness. My mom (also a Fibro family member) mentioned that her doctor told her that Fibro does have an effect on the eyes.....but it varies. She can go days without her glasses and other times she needs them very much.
The headaches and eye strain are annoying. I am trying glasses for the first time in my life ( I added the anti-glare lens). I will let you know how it works out.
