Artificial light sensitivity: what it can mean and what to do

The discomfort may be triggered by bright LEDs, fluorescent lights, glare, flicker, or screens. It is often called photophobia, although the problem is discomfort or pain rather than a fear of light.

Migraine commonly presents with light sensitivity, sometimes alongside headache, nausea, or visual disturbance. Conjunctivitis can present with irritation, redness, discharge, and sensitivity to light. Dry eyes, an uncorrected vision problem, medication effects, and recovery after an eye procedure can also make artificial light harder to tolerate.

A clinician will consider whether one or both eyes are affected, whether natural light causes the same response, and whether the symptom began suddenly. The pattern and accompanying symptoms matter more than the type of bulb alone.

Reduce direct glare, use softer indirect lighting, lower screen brightness to match the room, and take regular breaks from close screen work. A matte screen filter may help if reflected light is the trigger. Avoid driving if glare or visual disturbance makes it difficult to see clearly.

Keep a brief record of the lighting involved, the time symptoms start, headache or eye symptoms, and any recent medicine changes. Arrange an eye or medical assessment if the problem persists, recurs, or interferes with normal activities. Wearing very dark glasses indoors for long periods may make ordinary light feel harder to tolerate.

Seek urgent medical care for sudden light sensitivity with severe eye pain, a red eye, reduced vision, an eye injury, chemical exposure, a severe headache, fever, stiff neck, confusion, weakness, or repeated vomiting. Meningitis can present with light sensitivity together with severe systemic symptoms and requires emergency assessment.

Remove contact lenses if an eye becomes painful or red, and do not put them back in until a clinician has assessed the eye. After chemical exposure, rinse the eye immediately with clean running water while arranging emergency help.

Ask whether you need an eye examination, whether migraine could explain your pattern, and whether any current medicine can increase sensitivity. Mention contact-lens use, recent eye procedures, changes in vision, discharge, headache, nausea, fever, or neck stiffness.
