Which condition can prolonged exposure to UV rays contribute to?

Prolonged exposure to UV rays can contribute to the development of cataracts, which is a clouding of the lens of the eye that can impair vision. UV radiation, particularly from the sun, can cause damage to the lens over time. This damage may lead to the formation of cataracts, as UV light can cause changes in the protein structure of the lens, resulting in opacity and reduced transparency.

In contrast, myopia (nearsightedness), astigmatism (irregular curvature of the cornea or lens), and presbyopia (age-related loss of near vision) are conditions related to the shape of the eye, refractive errors, or aging processes, rather than being directly linked to UV exposure. Therefore, the association between UV rays and cataracts highlights the importance of protecting the eyes from excessive sun exposure through the use of UV-blocking sunglasses to help prevent this condition.
