Which organs are listed as affected by UV radiation?

• A. Skin
• B. Eyes
• C. Skin and Eyes
• D. Lungs

Answer: (C)

UV radiation affects tissues that are directly exposed and sensitive to skin cells and the structures of the eye. The skin and eyes are the primary organs at risk because UV photons reach the outer surfaces where damage can occur: in the skin, UV exposure can cause sunburn, accelerate aging, and increase cancer risk by damaging DNA; in the eyes, UV can harm the cornea and lens, leading to issues like photokeratitis and a higher chance of cataracts over time. The lungs aren’t directly exposed to UV radiation in everyday settings, and UV light doesn’t reach internal organs in meaningful amounts, so they aren’t typically affected by UV exposure. That’s why the option listing skin and eyes is the best answer. Protective measures include sunscreen, protective clothing, and sunglasses with UV protection.
