Which vitamin is particularly important for vision and can be affected by fat absorption issues?

1. Vitamin D

2. Vitamin E

3. Vitamin A

4. Vitamin K

The correct answer is: Vitamin A

Vitamin A is particularly important for vision because it plays a crucial role in the formation of rhodopsin, a protein in the retina that allows for the perception of light, especially in low-light conditions. This vitamin is essential for maintaining healthy vision and preventing night blindness. Furthermore, Vitamin A is a fat-soluble vitamin, which means its absorption in the body is dependent on dietary fat. Individuals with fat absorption issues, such as those with certain gastrointestinal disorders or conditions like celiac disease, may struggle to absorb adequate amounts of Vitamin A, which can lead to deficiencies and affect their vision. The other vitamins listed—Vitamin D, E, and K—although important for various bodily functions, do not have the same direct association with vision as Vitamin A does.
