Hi there. I have posted this same question for about 5 years off and on. I just thought I'd try again to see if any new information is out there. For 10 yrs. now, when I wake up, one or both of my eyes is blurry. What's odd is, it is 'usually' one or the other. For example, yesterday my right eye was blurry, & today, my left eye is blurry. It will stay this way for about 3 hours or more, then clears up. Some days both eyes are fine. I have went to 4 different eye doctors, optometrists and ophthalmologists both. They either seemed aggravated that I came in and they didn't find anything or said it 'looked like' dry eyes. None of the eye Dr.s could find anything unless I came back while my eye(s) were blurry. As far as any medical problems, nothing has ever came up. I had all kinds of tests when I had my 2nd child 5 years ago.......everything was fine (diabetes, whatever else they test for). I have never read or heard ever, that dry eyes causes blurred vision. I had been using TheraTears eyedrops, 4 times a day, which seemed to help, but if I let up at all, one eye would go blurry. I am mainly wanting to know if anyone else has went through this or even heard of this. I just don't want something worse to come out of this in years to come! --- something that the Eye Doctors have over-looked. Thanks for your time and help.
