Vitamin C in red grapes also plays a crucial role in maintaining the health of the cornea and the retina, reducing the risk of cataracts and other eye disorders. Furthermore, the anti-inflammatory properties of anthocyanins in red grapes may help reduce inflammation in the eyes, which can contribute to various eye diseases.
