Vision problems are associated with deficiency of which vitamin?

• A. Vitamin D deficiency
• B. Iron deficiency
• C. Vitamin A deficiency
• D. Vitamin C deficiency

Answer: (C)

Vitamin A is essential for eye health because it forms rhodopsin, the pigment in the retina that allows you to see in low light. When vitamin A intake is insufficient, night blindness can occur and the surface of the eye can become dry and damaged, a condition that can progress to more serious eye problems if not addressed. This is why vitamin A deficiency is strongly linked to vision issues, including dryness of the eyes and potential loss of vision with prolonged deficiency. Sources include animal products like liver, dairy, and eggs, as well as beta-carotene from colorful fruits and vegetables such as carrots, sweet potatoes, spinach, and fortified foods. Other listed vitamins affect different systems—Vitamin D mainly bones, iron deficiency causes anemia, and vitamin C deficiency leads to scurvy symptoms—so they do not have the same direct connection to vision problems.
