Which protective measure may help deter progression of an ocular nevus?

• A. UV protection
• B. Regular bright light exposure
• C. High-fat diet
• D. Avoiding sunscreen

Answer: (A)

Exposure to UV light can damage pigmented cells in the eye and may increase the risk that a benign ocular nevus could progress toward melanoma. Wearing UV-blocking eyewear—sunglasses that block 100% of UV-A and UV-B light, ideally with wraparound protection and a wide-brimmed hat—reduces cumulative UV exposure to the eye and may help deter progression. The other options don’t target UV-related risk: regular bright light exposure can cause phototoxic damage, a high-fat diet isn’t linked to nevus progression, and avoiding sunscreen wouldn’t shield the eye from UV radiation.
