Which condition can be caused or accelerated by unfiltered UV exposure?

Unfiltered UV exposure can lead to several eye conditions, notably cataracts and pterygium, making the choice that includes both of these conditions the most accurate.

Cataracts are characterized by the clouding of the lens in the eye and can develop as a direct result of prolonged exposure to ultraviolet (UV) rays. The UV rays cause changes in the lens’s protein structure, leading to the formation of cataracts over time. Therefore, individuals who are frequently exposed to UV light, such as those who spend a lot of time outdoors without proper eye protection, are at an increased risk of developing cataracts.

Pterygium is another condition related to UV exposure. It involves the growth of benign tissue on the conjunctiva, typically extending onto the cornea. This growth is often associated with environmental factors, particularly UV light. Ultraviolet rays can stimulate the abnormal growth of this tissue, leading to pterygium, especially in individuals living in sunny climates or those who engage in outdoor activities without adequate UV protection for their eyes.

While strabismus is a condition related to the misalignment of the eyes, it is not directly caused or accelerated by UV exposure. Therefore, the inclusion of both cataracts and pterygium in
