As UV-B suppresses the skin s immune responses, the body s immune system is less likely to reject a growing tumour. Increasing eye damage Research shows that the eyes become more sensitive with repeated exposure to excessive radiation. This applies to animals as well as to human beings. UV-B radiation can damage the cornea, the lens and the retina. The eye first responds to UV-B radiation by developing snow blindness.
Further exposure can cause cataracts.
Cataracts are already the largest cause of blindness in the world.
