I have a similar problem with my vision. Over the last few years, two or three times a year, my vision suddenly goes blurry, and blinking or rubbing my eyes doesn't correct the problem. I stopped driving because of this. It isn't frequent, as I said, but can you imagine being in 5 lanes of traffic going 70mph, and suddenly your vision is wiped out?

Because it is so infrequent, I have not told my doctor about it. But over the last few month it has occurred both indoors and on a hiking trail, for about a full minute. My first thought isn't so much, "meds," because I've switched meds several times in the last few years, but instead I think, "brain tumor," one of which just killed my father.

Hard to tell if this has something to do with my eyeglasses, or my SZA, or a tumor. I go to see my doctor in a few months, and this time I'll share this experience with him. I hope he's heard it before and will know what to do.
