Light sensitivity, also known as photophobia, is a condition where bright lights cause discomfort or pain in the eyes. This sensitivity can be triggered by various factors, including certain medical conditions, medications, or even environmental factors like glare from the sun. People with light sensitivity may squint, close their eyes, or seek darker environments to alleviate discomfort. Individuals with migraines or conjunctivitis often experience heightened light sensitivity. It can also be a symptom of meningitis or corneal abrasions. Treatment options may include wearing sunglasses with polarized lenses, using anti-reflective coatings on glasses, or managing underlying health issues to reduce symptoms.
