The vitamin that primarily supports vision is Vitamin A. This essential nutrient plays a pivotal role in maintaining eye health and vision, particularly in low-light conditions. Vitamin A is involved in the production of rhodopsin, a pigment in the retina that allows the eyes to perceive light and color accurately. Additionally, it helps in the maintenance of healthy corneas and may protect against age-related vision issues. Sources of Vitamin A include liver, fish oils, dairy products, and plant-based foods like carrots, sweet potatoes, and leafy greens, where it exists as beta-carotene.
