yes, you are not alone. I also have suffered the blurriness for years now, ongoing and usually in ONE eye at a time, although it varies as to which eye will be the problem eye. And it is worse when I'm tired or if I'm doing a lot on the computer. I've had multiple exams and they only say dry eye, which of course is a good catch all for everything.
I am not saying it isn't dry eye, but it seems like something else to me as well is going on. Sometimes it feels like I've got vaseline in my eye. is that how you feel?
I've also discovered that when I wake up in the middle of the night my one eye will hurt to open it. That's a new development. and again, my eye doctor can't find anything wrong.
Very scary, and very frustrating.
I am also nearsighted with astigmatism and do have to wear glasses for everything pretty much.
I just wanted to reply to let you know that there's at least one other person who shares your plight and sure wish I had an answer. If I find out anything I will post again
