More than 80% of men and women with cluster headache report light sensitivity as a symptom during migraine attacks.
Light sensitivity, also called photophobia, is a common migraine symptom. Light is one of many migraine triggers, and study shows that photophobia has been reported in all types of migraines, along with many neuro-ophthalmic disorders.

People who get tension and cluster headaches also say they’re uncomfortable around bright light. Also there are a few brain conditions that cause light sensitivity:
