The vitamin important for eye health found in carrots is vitamin A, specifically in the form of beta-carotene. This nutrient plays a crucial role in maintaining healthy vision, particularly in low-light conditions. Vitamin A is essential for the formation of rhodopsin, a protein in the eyes that enables us to see in dim light. Additionally, it contributes to the overall health of the retina and may reduce the risk of age-related macular degeneration. Including carrots and other vitamin A-rich foods in your diet can support long-term vision health.
