We donât really know why migraines cause light sensitivity, but itâs clear nearly everyone with migraine will tell you that they have sensitivity to light during an attack and many patients with migraine will tell you that certain kinds of light can trigger an attack (particularly those found in big box stores such as Target and Walmart).

For many years, scientists believed that migraines were linked to the expanding (dilation) and constriction (narrowing) of blood vessels on the brainâs surface.
