I see a silver flash when I blink my eyes on my right side like a semi-circle shape... basically it looks like this ( ... It only happens when I blink, and not every time, maybe 80%of the time. I have also become very sensitive to sunlight. I went to the Opthamologist but I cant help thinking they missed something because they said they didnt see anything. This has been going on for a few weeks now. I am quite concerned. I am used to migraines, however, my auras never last for weeks.. usually hours...and I havent had any more than usual headaches. I am going through early menopause and am currently experiencing a large amount of Hot Flashes, and I am also Hypoglycemic. I wasn't sure if these issues could be the cause of concern but thought I should mention them. I am 40 yrs old.
