1. Let's Start At The Beginning...Vitamin A
Your mother was right when she told you carrots were good for your eyes. Carrots are high in Vitamin A, which is important for vision. Vitamin A is a group of nutritional compounds. It includes retinol, retinal, retinoic acid and several carotenoids, such as beta-carotene.

Vitamin A strengthens the immune system, prevents cancer and heart disease and improves bone health. Other food sources for Vitamin A are beef liver, sweet potato, kale, spinach, broccoli, winter squash, butter and egg yolks.
