These bright light spots begin in the outer upper right corner and go downward. The occurrance is at least once every half hour, and have been occuring for about a week. I have no headaches and have not had any eye injury. There is no pain, just the annoyance of bright light. The best way to describe it is: it feels like a bright flashlight is being shone in the outer corner of my eye and then turned off after about 4 seconds.
