Can migraines cause flashing lights?
Some people experience flashing lights that appear as zigzag or jagged lines of “heat wave” appearance in both eyes preceding the onset of a migraine headache. Typically, this visual symptom lasts 10 to 20 minutes, and then gradually fades away on its own. Commonly, a migraine headache, nausea, weakness, or dizziness can follow this. On some occasions, no other symptom of headache or other migraine symptom follows the eye symptom. If this is a new occurrence for you, a complete eye exam is indicated; however, if you have had these before with your migraines you need to watch to be sure the symptoms clear over a normal time frame.
