Snow blindness arises due to

Options:
A UV-A
B UV-B
C UV-C
D More than one option is correct

The correct answer is:
UV-B

Solution:
UV radiation of wavelengths shorter than UV-B, is almost completely absorbed by Earth’s atmosphere, given that the ozone layer is intact. But, UV-B damages DNA, and mutation may occur. It causes aging of the skin, damage to skin cells, and various types of skin cancers. In the human eye, cornea absorbs UV-B radiation, and a high dose of UV-B causes inflammation of the cornea, called snow-blindness, cataract, etc. Such exposure may permanently damage the cornea.
