What causes you to see bright lights when you have migraines?
A doctor has provided 1 answer
Aura: The bright lights or "scintillating scotomata" are due to dysfunction over the occipital lobe of the brain, and a response to the emerging neurochemical changes which proceed from back of brain forwards, eventuating in the full blown headache.
