Which vitamin is crucial for maintaining vision and eye health?

Vitamin A is vital for maintaining vision and overall eye health. It plays a critical role in the formation of rhodopsin, a pigment found in the retina that helps the eyes adapt to low light conditions and contributes to night vision. Furthermore, Vitamin A is essential for the maintenance of healthy epithelial tissues, including those in the eyes, which can help prevent dryness and other eye-related issues.

Deficiency in Vitamin A can lead to serious vision problems, such as night blindness and even more severe conditions like xerophthalmia, which can result in complete vision loss if not addressed. While other vitamins, such as B12, C, and D, have important roles in various bodily functions, none of them are as directly linked to visual acuity and eye health as Vitamin A. This specificity of Vitamin A in relation to the eye emphasizes its unique and crucial role in maintaining visual function.
