I had this happen to me about a year ago, all of a sudden I saw flashing in the corner of my eye. It continued on for about a week, then I had a shower of floaters in my eye, the flashing stopped and the floaters eventually mostly went away, I still have a few in that eye. If you look up eye flashing on the internet, I think it says it could be a detached retina, or the lining in the back of the eye sloughs off with age. I didn't go to the doctor (my bad I know), because I hadn't hit my head or anything to cause a detached retina. I now take Andre Lessman's Ultimate Eye Support along with his Astaxanthin, which you can get on HSN.com. if you go on website read all 
the reviews on these products, and you'll see that these have helped with the tissue in the eye that we don't get from our diets. I haven't had any problem with eye flashing since.     |
