Some people experience flashes of light that look like jagged lines or “heat waves” in both eyes, often lasting 10 to 20 minutes. These types of flashes are usually caused by a spasm of blood vessels in the brain. If a headache follows the flashes, it is called a migraine headache.
However, you can experience the jagged lines or heat wave flashes and not have a headache. In this case, the light flashes are called ophthalmic migraine, or migraine without headache. Contact our office if you experience these symptoms.
