Photophobia is a condition characterized by an increased sensitivity to light. People with photophobia may experience discomfort or pain in bright environments, which can lead to squinting or avoidance of light. This sensitivity can be caused by various factors, including migraines, eye conditions, or neurological disorders. Symptoms of photophobia can vary in severity and may be triggered by natural sunlight, fluorescent lights, or even certain colors. Treatment often involves managing the underlying cause, using sunglasses or hats to reduce light exposure, and in some cases, medications to alleviate associated symptoms.
