It seemed worse while on Gabapentin but now that I have been off it for several months it is not as bad. My underlying cause was Diabetes plus trauma. I feel the blurriness worse after eating a meal and getting out driving. It may be that driving alone causes more blur due to the need for focus. Or the meal may take the blood sugar too high for a while, who knows? Anyway, as a diabetic I am always ready to blame it. Annoying is right, every time I need both eyes one of them needs a rub. Hang in there, Ken in Texas. P.S. After reading Mrs.D and Beatle's posts I will mention that my B-12 was @119 following a car wreck and had probably been low for years.
