Abstract: food rich in vitamin C can reduce the damage of light and oxygen to the eye lens, so as to delay the occurrence of cataract. Foods containing vitamin C include fresh vegetables and fruits such as persimmon pepper, tomato, lemon, kiwi fruit and hawthorn.
what is better for high myopia? To protect eyesight and prevent eye diseases, we need to start from many aspects. Paying attention to nutrition also helps to improve eyesight…
I. vitamin a food
food rich in vitamin A, vitamin A is closely related to normal vision. If vitamin A is insufficient, the regeneration of rhodopsin is slow and incomplete, the dark adaptation time is prolonged, and night blindness is caused in severe cases. If vitamin A in the diet continues to be deficient or insufficient, dry eye disease will appear. The further development of the disease can become corneal softening and corneal ulcer, corneal wrinkle and Pitt’s spot. The best food source of vitamin A is all kinds of animal liver, cod liver oil, fish eggs, poultry eggs, etc; Vitamin A contained in vegetables such as carrot, spinach, amaranth, alfalfa, sweet potato, pumpkin and green pepper can be transformed into vitamin A in the body.
II. Vitamin C food
food rich in vitamin C. vitamin C can reduce the damage of light and oxygen to the eye lens, so as to delay the occurrence of cataract. Foods containing vitamin C include fresh vegetables and fruits such as persimmon pepper, tomato, lemon, kiwi fruit and hawthorn.
III. calcium in calcium containing food
is related to the composition of the eyeball. Calcium deficiency can lead to myopia. Teenagers are at the peak of growth, and the demand for calcium in the body is relatively increased. If they do not pay attention to calcium supplement, it will not only affect bone development, but also reduce the elasticity of the developing eyeball wall sclera and increase the pressure in the lens, resulting in the elongation of the anterior and posterior diameter of the eyeball and leading to myopia. Foods containing more calcium mainly include milk and its products, shells (shrimp), bone meal, beans and bean products, egg yolk and dark green vegetables.
IV. chromium deficiency in chromium containing food
is prone to myopia. Chromium can activate insulin and make the islets play the greatest biological effect. If the content of chromium in the human body is insufficient, it will hinder the function of insulin in regulating blood glucose, increase the plasma osmotic pressure, increase the osmotic pressure and diopter of ocular lens and aqueous humor, and induce myopia. Chromium mostly exists in brown rice and wheat bran, and animal liver, grape juice and nuts are also rich.
v. zinc deficiency in zinc containing food
can lead to visual impairment. Zinc is mainly distributed in bones and blood in the body. Zinc is also contained in the corneal epidermis, iris, retina and lens. Zinc participates in the generation} and transportation of vitamin A in the eye, maintains the normal tissue state of retinal pigment epithelium and maintains normal visual function. Foods containing more zinc include oysters, meat, liver, eggs, peanuts, wheat, beans, Cereals, etc.
