What Causes Migraines?

Bright Lights And Glare

More than seventy percent of migraine patients experience sensitivity to bright lights and glare during migraine attacks. This sensitivity is slightly more common in young adults under forty years old. Patients affected by lights and glare could experience pain when exposed to flickering lights, flashing lights, or sunlight. High-contrast lights, blue-green light wavelengths, and the invisible pulsations of fluorescent lighting could also be painful for affected individuals. Many patients have more frequent migraines during the summer when sunlight is especially intense. Some patients may find light sensitivity lingers for several days after a migraine attack, and this may be severe enough that the patient needs to wear tinted glasses while indoors. Lying down in a dark room during periods of light sensitivity is often helpful. Patients should always let their doctor know about any new or worsening light sensitivity.
