The vitamins that help with vision are primarily Vitamin A and its derivatives, such as beta-carotene. Vitamin A is crucial for maintaining good eyesight, particularly in low-light conditions, as it plays a vital role in the formation of rhodopsin, a protein in the retina that absorbs light. Deficiency in Vitamin A can lead to serious vision problems, including night blindness and more severe eye conditions. Foods rich in Vitamin A include liver, carrots, sweet potatoes, and dark leafy greens, which are important for preserving ocular health.
