Does anyone have to wear sunglasses because the sun is way too bright at times?
I can think of a couple of things you might want to check. First of all is your medications. A couple of the common fibro meds can cause vision issues. Talk to your pharmacist, they are usually the best source of information on medication side effects. Also look at trigger points in certain head/neck muscles that can cause issues. The Trigger Point Therapy Workbook by Clair Davies NCTMB has been helpful for me. WWW.YOUTUBE.COM also has trigger point information. I find that most of us with fibro have "trigger" point issues as well as the infamous "tender" points.
I too fund it hard to focus even with my glasses on and my eyes feel permanently strained and as if they want to just close all the while I'm trying to read articles write ect! Not my sight that hasn't changed appatently according to my optician but my vision goes blurred ect.
Wow mine to... not long had them tested and was told no change but I find myself squinting to see properly even with my reading glasses on...
