Our eyes are like a precision camera. Under the premise of normal refraction and still, the things in front of us can’t converge on the retina, but form the focus before the retina, so that the focus can’t be focused is fuzzy. There is only one reason for this result. The front and back wheelbase of the eyeball is lengthened. The reason for lengthening the wheelbase is that the eyes are tired for a long time and the lens cannot recover. At the very beginning, our eyes blurred and rest would alleviate (pseudmyopia). If you still don’t pay attention and use your eyes excessively, you will become really shortsighted if you can’t pull it back one day
The following 7 kinds of food are very helpful for the eyes and can reduce myopia：
Vitamin A: to prevent dry eyes, eyesight decline, night blindness, known as “the need to protect the eyes”, carrot, green and yellow vegetables and jujube are the most abundant;
Vitamin B: one of the nutrition sources of the visual nerve, vitamin B1 is insufficient, and the eyes are easy to fatigue; vitamin B2 is insufficient, which is easy to cause keratitis. Can eat more sesame, soybean, fresh milk, wheat germ and other food;
Vitamin C: it has antioxidant effect, prevents the retina from being damaged by ultraviolet rays, prevents the aging of lens, repairs cells, and helps improve the health of eyeball. There are many foods rich in vitamin C, such as sour dates, kiwifruit, green peppers, strawberries, etc;
Vitamin E: antioxidant, can remove free radicals, mainly in nuts such as walnuts, peanuts, pine nuts, sunflower seeds;
Zeaxanthin: it can resist blue light, prevent vision degradation, and protect retina. The food source is mainly corn, pumpkin and spinach;
Anthocyanin: a very popular antioxidant in recent years. Medical clinical reports show that anthocyanin in blueberry can promote the regeneration of rhodopsin in retinal cells, prevent severe myopia and retinal detachment, and improve vision. Blueberries, black cherries, purple grapes, California plums, etc., all contain anthocyanins.
Anthocyanin can also enhance the elasticity of blood vessels, improve the circulatory system and skin smoothness, inhibit inflammation and allergy, and improve the flexibility of joints.
Lutein: a carotene that, like zeaxanthin, blocks out blue light that hurts the eyes. It can be obtained from onion, rape and cauliflower.
