I'm not sure this helps much, but I had to get glasses 3 or 4 months ago. I had better than 20/20 until this past year. I thought sure it was the DD or meds effecting my eyes. My GI said possibly, go see an eye doc. My eye doc said "almost 44, you're late! You should have been here 3 years ago." If it is ok to ask, what is your age?
I know it can effect your eyes, just as mine is causing me hip problems and bone density issues. Let the eye doctor make THAT final determination.
