Symptoms are typically delayed by 6 to 12 hours after exposure and include severe eye pain, foreign body sensation, intense light sensitivity (photophobia), and tearing.
The corneal epithelium is capable of rapid healing, and the condition usually resolves completely within 24 to 72 hours with supportive treatment (cool compresses, pain relief).
No. It is a sterile inflammatory response to a chemical/radiation burn, not an infection.
Yes. Wearing $100\%$ UV-blocking, wrap-around sunglasses and UV-protected safety goggles during high-risk activities provides complete prevention.
Fresh snow can reflect up to $80\%$ of incident UV radiation, dramatically increasing the dose of exposure to the eyes.
