Burning eyes and light sensitivity: what to know

Dryness, smoke, dust, prolonged screen use, or contact-lens irritation can make the eye surface sting and make light uncomfortable. Conjunctivitis can cause burning, redness, watering, or discharge. Migraine can cause light sensitivity with head pain, nausea, or visual symptoms even when the eyes look fairly normal. Meningitis is uncommon but may cause severe headache, fever, neck stiffness, vomiting, or marked light sensitivity; these symptoms need emergency assessment.

Move away from smoke, dust, and harsh light. Rest your eyes, reduce screen glare, and use sunglasses outdoors. Do not rub your eyes or share towels. Remove contact lenses and avoid wearing them until symptoms have settled or a clinician has checked you. Preservative-free lubricating drops may soothe simple dryness, but do not use someone else’s eye medicine or leftover antibiotic drops. Arrange an eye or medical review if the discomfort persists, recurs, or affects daily activities.

Seek urgent care for sudden vision loss or blurring, severe eye pain, a very red eye, injury, chemical exposure, unequal pupils, or symptoms after a contact-lens problem. Emergency help is needed for light sensitivity with fever, stiff neck, confusion, fainting, or a severe sudden headache. A clinician may examine the cornea, check vision, and look for inflammation or infection.

Ask whether the pattern suggests surface dryness, conjunctivitis, migraine, or another eye condition; whether contact lenses or medicines could be contributing; which drops are suitable; and what changes should prompt urgent review.
