What nutrient is good for your eyesight?

Vitamin A is essential for good eyesight as it helps maintain healthy vision and is crucial for the function of the retina. It prevents night blindness and supports overall eye health. Additionally, antioxidants like lutein and zeaxanthin, found in leafy greens and other colorful fruits and vegetables, can help protect the eyes from harmful light and reduce the risk of age-related macular degeneration.
