Which are common signs of arc eye (photokeratitis)?

• A. Pain, tearing, light sensitivity
• B. Rash on hands
• C. Headache and dizziness
• D. Numbness in feet

Answer: (A)

Arc eye, or photokeratitis, is a UV burn of the cornea from the welding arc. The most common signs are eye pain, tearing, and sensitivity to bright light. The cornea becomes irritated by the UV exposure, so small nerves trigger pain, tears flow to rinse the irritant, and light becomes uncomfortable or painful (photophobia). These symptoms directly reflect the corneal surface damage caused by the arc. The other choices don’t fit because a rash on the hands is a skin reaction, not an eye issue; headaches and dizziness can happen for many reasons but aren’t specific signs of an ocular UV burn; numbness in the feet isn’t related to the eyes. To prevent arc eye, always wear proper eye protection with adequate UV blocking and a suitable shade for the welding task. If symptoms occur, limit further exposure and seek medical advice, since treatment focuses on soothing the eye and allowing healing while protecting the eye from light exposure.
