Every couple of months I have a shimmering in my eyes, almost like when a fluorescent light is burning out that is about the best way to describe it and as I said it does not happen all the time. I wear my glasses for driving and reading but this sensation comes out of no where, it can happen if I am shopping, I have to sit down and just close my eyes and relax then after approx. 10-15 minutes it goes away. I know that there is such a thing as an eye migraine ???? The last time I had my eyes examined, the Dr. did not seem to be too concerned but you hear all kinds of horror stories, just curious. Thank you
