What Is Snow Blindness?
Exposure to ultraviolet (UV) radiation may lead to a painful eye ailment known as snow blindness, sometimes called arc eye or photokeratitis. The clear cornea, which is the outermost layer of your eyes, becomes sunburned when too much UV radiation strikes it. However, after you protect yourself from UV rays and give your eyes some rest, snow blindness is simple to cure, and your eyes will recover rapidly.
Causes of Snow Blindness
Overexposure to UV radiation, whether intentional or accidental, may result in photokeratitis. In the term "photo," the "photo" component refers to "light," and keratitis is an inflammation of the cornea. Your cornea's delicate outer layer gets inflamed and irritated when too much UV radiation strikes it, which results in a burning or itchy sensation. Inflammation of the cornea and snow blindness may also be brought on by the light from blowtorches, sunlamps, and tanning beds.

Symptoms of Snow Blindness
Symptoms of photokeratitis don't usually show up immediately. In other cases, symptoms won't appear until many hours after your corneas have been injured. Common signs include:
- Pain and burning sensation in eyes
- Feeling like there is something in your eye that you can't get out
- Responsiveness to light
- Red and swollen eyelids
- Dripping eyes
- Migraine clouded vision
- Excessive glare from the lights inside
Final Answer
Inflammation of the cornea is known as keratitis. Excessive absorption of UV-B radiation in high doses causes snow blindness or photokeratitis. It is characterised by temporary eye pain and discomfort.
Thus, snow blindness represents the inflammation of the cornea.
