Foods rich in vitamins a, b and c as well as foods containing lutein are good for eye sight. Foods rich in vitamin a include animal liver, broccoli, carrots, blueberries, etc. These foods can prevent corneal softening and promote the development of retinal function. Foods richer in vitamin B, commonly found in black rice, sesame seeds and soybeans, are good for promoting the development of the optic nerve. Foods rich in vitamin c, such as green leafy vegetables like greens and fruits like oranges and kiwis, can be antioxidant and prevent the occurrence of cataracts, macular degeneration and other diseases. Foods rich in more lutein, including egg yolks, spinach, corn, etc., can reduce the probability of oxidation and degeneration of the retina. A balanced diet with adequate nutrition is recommended.
