How long do Arc Eye symptoms typically last before disappearing?

• A. 12 to 36 hours
• B. 1 to 2 days
• C. 2 to 4 days
• D. 1 week

Answer: (A)

Arc Eye, or photokeratitis from UV exposure to the cornea, is a temporary, superficial injury that heals quickly because the corneal epithelium regenerates rapidly. After exposure, the irritation and symptoms peak within hours and then fade as the surface repairs itself, typically within about 12 to 36 hours. This short recovery window fits the nature of a shallow corneal burn. Longer durations (2–4 days or a week) would suggest a more severe injury or different condition, not the typical Arc Eye course. If symptoms persist beyond a day or two or pain is severe, seek medical evaluation.
