You can get migraines with or without aura. They often start out similar to when you look into a light bulb or bright sun but the bright light turns to flashy colors. I have had them come and go quickly, and then other times swirl in my eye for quite awhile.
If it persists with you, I would definately contact your doctor and get checked out.
