📝 Summary
In short: A painful, temporary 'sunburn' of the eye's surface from intense UV light off snow, water, or sand — it heals on its own with rest in the dark.
Common causes: Intense UV light reflected off snow, water, ice, or sand; High-altitude sun without eye protection; Welding or sunlamps without proper eye protection.
First thing to try: Get out of the bright light and into a cool, dark room, and remove contact lenses.
See a doctor if: Pain or blurred vision that doesn't improve within a day or two
🌿 Overview
Snow blindness (photokeratitis) is essentially sunburn of the cornea, caused by intense ultraviolet light reflected off snow, water, sand, or from welding without eye protection. It's painful but temporary, and the eye's surface heals on its own within a day or two.
Strong UV light burns the delicate surface of the eye, and a few hours later the eyes become painful, gritty, watery, and very sensitive to light, sometimes with blurred vision. It's common in skiers, mountaineers, and at the beach without good sunglasses.
The care is simple: get out of the bright light, remove contact lenses, rest the eyes in a dark room, and use cool compresses and lubricating drops for comfort. It heals within a day or two. UV-blocking sunglasses or goggles prevent it. Any pain or vision change that doesn't settle, or any chemical or impact injury, needs an eye doctor.
Common signs
- Painful, gritty, watery eyes a few hours after strong UV exposure
- Strong sensitivity to light and blurred vision
- Redness and a feeling of sand in the eyes
- Sometimes temporary loss of vision (it returns)
