Which parts of the eye are commonly damaged by exposure to UV radiation?

• A. Retina
• B. Cornea
• C. Lens
• D. All of the above

Answer: (D)

UV radiation can affect multiple eye structures because the energy interacts with tissues at the surface and deeper inside the eye. The cornea, as the front surface, is very sensitive to UV and can suffer photokeratitis after short, intense exposure. Over longer periods, UV exposure can contribute to cataract formation in the lens. While the retina is deeper and generally protected by the cornea and lens, high-energy UV or prolonged exposure can still cause photochemical damage there. For these reasons, all of the listed parts can be damaged by UV radiation, making all of the above the best answer. To reduce risk, wear sunglasses that block 100% of UV-A and UV-B and consider protective eyewear in bright, reflective environments.
