Vitamin A prevents night blindness and focal drying of the eyes called Xerophthalmia and can retard the development of cataracts and macular age related changes.
You can get vitamin A from two types of food sources: Animal products that contain vitamin A (such as liver or butter) or plant products that contain carotene, which your body converts into vitamin A. Foods containing carotene are usually yellow or orange, or leafy and green.
Lutein and Zeaxanthin can also be very helpful for maintaining retinal health. Not only do they delay changes in the retina but also act as good protection. The best source of lutein and zeaxanthin is green, leafy vegetables, particularly spinach. Kale and collard greens are also good choices. You can also find lutein and zeaxanthin in yellow and orange fruits and vegetables, such as corn.
