- Corneal epithelial damage caused by direct exposure to ultraviolet (UV) light
- Also known as photokeratitis, UV conjunctivitis, snow blindness, and welder's flash
- Work-related exposure seen in welders, electricians, and mechanics
- Recreational exposure, including water sports, snow sports, and tanning booths
- Occurs with corneal absorption at 290 nm, the cutoff between UV-B and UV-C light
- UV light penetrates to epithelial nociceptor axons, destroying them and triggering pain from subendothelial nerve stimulation
- Related to intensity and duration of exposure
- Long-term UV damage to eye may result in pterygium and some forms of corneal degeneration, though association with UV keratitis episodes has not been demonstrated
