Keratitis can be aggravated and even caused by contact lens use. Don’t rub your eyes while you have symptoms of photokeratitis. If you wear contact lenses, remove them until your symptoms have subsided. Resting your eyes away from UV light is the best way to encourage healing. There’s not much your doctor can do to treat photokeratitis. Symptoms tend to resolve gradually over a day or two, according to the American Academy of Ophthalmology.Ī doctor can confirm whether you have photokeratitis by examining your eyes for UV damage. Snow blindness usually goes away on its own once your corneas recover. People who use welding equipment for a living are particularly prone to “welder’s flash” - another name for snow blindness. Light from blowtorches, sun lamps, and tanning booths can also cause inflammation of the cornea and lead to snow blindness. UV rays reflected off sand, snow, and water can burn your cornea and cause photokeratitis. When too much UV light hits your cornea, this sensitive outer layer becomes inflamed and irritated, causing a feeling of burning or itching. It has thousands of nerve endings, making your cornea very sensitive to any damage or pain. The outermost layer of the cornea is called the epithelium. Your cornea doesn’t contain blood vessels, so it needs tears to stay lubricated and healthy. Your cornea is the clear, dome-shaped tissue that covers your eye. The “photo” part of the word means “light” and keratitis is an inflammation of your cornea. Photokeratitis is caused by natural or artificial overexposure to UV light.
