Which of the following is listed as a key nutrient for cataracts?

• A. Lutein, Vitamin E, Vitamin C, Selenium.
• B. Lutein and Vitamin C only
• C. Vitamin A, Vitamin D, Zinc
• D. Selenium and Vitamin E only

Answer: (A)

Cataract formation is driven in part by oxidative damage to the lens, so nutrients with antioxidant actions are protective. Lutein sits in eye tissues and helps filter light while acting as an antioxidant, reducing oxidative stress on lens proteins. Vitamin E is a fat-soluble antioxidant that guards lens cell membranes from lipid peroxidation. Vitamin C in the aqueous humor provides additional antioxidant defense against reactive oxygen species in the lens environment. Selenium serves as a cofactor for glutathione peroxidase, an enzyme that helps neutralize peroxides in ocular tissues. Together, these nutrients are commonly listed as key supporters of lens health and cataract prevention. Other nutrients like vitamin A or zinc have important roles for vision in other contexts, but they’re not as consistently linked to cataract protection, and vitamin D has a less clear connection.
