After being exposed to bright light my vision field is spotty with bright lights. I have a similar experince when I'm hypoglycemic often my first sympto but this type is unrelated to my BLOOD SUGAR. mY LATEST MEDS ADDED ARE Cardizem for A-fib, coumadin which is closely monitored, I was started on dexedrine in Jan. for narcolepsy but did not suffer from this. The bout of a-fib and the meds was at the end of February and has become more pronounced in the past week. I also have a history of bipolar. Thank you for your assistance. A better way to describe it is like I looked at the sun too long but only glanced at it. I have not experienced it with my bipolar meds, which are celexa, lamictal and resperidone. ThaNK YOU.
