Eating foods rich in vitamin A, carotenoids, anthocyanins and lutein is generally good for the eyes. 1. Vitamin A: Vitamin A can participate in the maintenance of dark vision photoreceptor circulation within the visual cells to maintain good dark vision. Common foods include animal offal, carrots, spinach and egg yolk. 2. Carotenoids: Common foods include pumpkin, corn, carrots, etc. Carotenoids can constitute the photoreceptor substances in the visual cells to avoid the damage caused by the glare of dark vision on the eyes. 3. Anthocyanins: Anthocyanins are usually able to enhance night vision and slow down macular degeneration of the eyes. Common foods include blueberries, grapes and purple sweet potatoes. 4. Lutein: Common foods include corn, pumpkin, kale, cauliflower and so on. Usually lutein can help the eyes filter blue light and ultraviolet rays, thus protecting the macula of the retina from damage.
