When the vitreous separates from the retina, you may see flashing lights once in a while, for a few weeks. If you see jagged lines of light that last 10 to 20 minutes and happen in one or both eyes, this is probably a migraine caused by the spasm of blood vessels in the brain. If you don't develop a headache after, the light flashes are called ophthalmic migraine, or migraine without headache.
