What condition can UV rays from the sun potentially lead to in the eyes?

Ultraviolet (UV) rays from the sun can have harmful effects on the eyes, one of which is macular degeneration. This condition involves the deterioration of the macula, the part of the retina responsible for sharp, central vision. Prolonged exposure to UV radiation can damage the retinal cells and accelerate the aging process in the eyes, leading to this degenerative disease.

Macular degeneration can significantly affect vision, making it harder to see fine details and affecting the ability to perform everyday tasks. The connection between UV exposure and macular degeneration underscores the importance of protecting the eyes from sunlight, such as wearing UV-blocking sunglasses.

The other choices do not reflect potential outcomes of UV exposure. Increased vision clarity and enhanced night vision are not related to UV exposure. Reduced glare sensitivity is also unrelated since excessive UV exposure can actually cause increased sensitivity to glare rather than a reduction. Thus, the choice highlighting the risk of macular degeneration effectively captures the serious implications of UV radiation on eye health.
