Detailed Solution

Concept- Due to ozone depletion, more UV radiation reaches Earth's surface, increasing the risk of skin cancer, cataracts, and immune system and genetic damage. Most often, this is seen at the poles.
Ozone depletion is the cause of snow blindness. Other names for snow blindness include photokeratitis and arc eye. The word "photokeratitis" refers to an inflammation of the cornea, and the word "photo" in the name implies "light." It is a painful eye ailment brought on by excessive UV (ultraviolet) light exposure. The cornea, which is the translucent outer layer of our eyes, becomes sunburned when excessive UV light strikes it.
Hence, the correct answer is option 1.
