What does it mean if you have flashes of light in your peripheral vision?

Peripheral vision: Auras are visual manifestations of neurological symptoms. Flashing lights are one type of aura people report seeing, and these auras often appear in either eye. Migraines are a common cause of visual disturbances, such as flashing lights, but these uncomfortable visual symptoms can be the result of other physiological conditions as well. Anxiety, retinal disease, htn, and seizures may be an issue.

Scotomatous vision: Most commonly associated with migraine. Can occur without getting the headache. Can be due to retinal event and or neurological problem strongly suggest seeing your physician.
