That’s all! A large collection of food sources for eye nutrition!

Abstract: vitamin A: rhodopsin is a compound protein containing vitamin A derivatives. If vitamin A is deficient or insufficient, the regeneration of rhodopsin will be slow and imperfect, which will reduce the dark adaptability and affect the night vision. Vitamin A deficiency can also cause corneal epithelium abscission, thickening and keratinization., Protein: rod-shaped cells in the retina, mainly dark vision; Cone cells are mainly myopic. Rod cells are sensitive to weak light mainly because they contain a special visual quality – rhodopsin, which is synthesized by protein and vitamin A. Lack of them will cause night blindness. The amino acids in the protein form a strong fibrous tissue, which can better protect the strong sclera and protect the eyes. Therefore, in order to protect good eyesight, we should first supplement enough high-quality protein., Supplementary food: lean meat, fish, milk, eggs and soybean products., Vitamin A: rhodopsin is a compound protein containing vitamin A derivatives. If vitamin A is deficient or insufficient, the regeneration of rhodopsin will be slow and imperfect, which will reduce the dark adaptability and affect the night vision. Vitamin A deficiency can also cause corneal epithelium abscission, thickening and keratinization. When vitamin A is sufficient, it can increase the smoothness of the cornea and make the eyes bright and energetic., Supplementary food: chicken, sheep, pig liver, cod liver oil, eggs, milk. Vegetables rich in carotene (vitamin A) include carrot, leek, coriander, broccoli, Chinese cabbage, amaranth, cabbage, mustard, alfalfa, golden needle, fennel, spinach, etc. However, because carotene is a fat soluble vitamin, it is easy to absorb only when fried in oil or mixed with fatty foods., Vitamin B1: it is an important vitamin that participates in and maintains the function and metabolism of nerve (including optic nerve) cells. If lacking or insufficient, it can make the eyes dry. It even causes inflammation of the optic nerve. Vitamin B1 can also flatten skin wrinkles, prevent and delay the formation of eyelids and skin crow’s feet., Supplementary food: lean meat, peanut, corn, millet, hard fruit, mushroom, etc. In addition, the intake of brown sugar should be reduced to avoid reducing the consumption of vitamin B1., Vitamin B2: it is an important nutrient to protect eyelids and bulbar conjunctiva. If the human body lacks vitamin B2, it is easy to cause conjunctival congestion, eyelid inflammation, photophobia and blurred vision., Supplementary food: animal viscera, eggs, peas, almonds, etc.,

vitamin B1: it is an important vitamin that participates in and maintains the function and metabolism of nerve (including optic nerve) cells. If lacking or insufficient, it can make the eyes dry. It even causes inflammation of the optic nerve. Vitamin B1 can also flatten skin wrinkles, prevent and delay the formation of eyelids and skin crow’s feet.

supplementary food: lean meat, peanut, corn, millet, hard fruit, mushroom, etc. In addition, the intake of brown sugar should be reduced to avoid reducing the consumption of vitamin B1.

vitamin B2: it is an important nutrient to protect eyelids and bulbar conjunctiva. If the human body lacks vitamin B2, it is easy to cause conjunctival congestion, eyelid inflammation, photophobia and blurred vision.

supplementary food: animal viscera, eggs, peas, almonds, etc.

vitamins C and E: they are important nutrients of lens. The content of vitamin C in ocular lens is significantly higher than that in other tissues. If vitamin C intake is insufficient, it can make the lens turbid and is one of the main causes of cataract.

supplementary food: grapefruit, citrus, fresh jujube, kiwi fruit and other fresh fruits and vegetables.

calcium: calcium participates in various nerve impulses in the human body. Nerve cells (including optic nerve) lack calcium and are prone to visual fatigue and distraction. Calcium is not only the main component of bone, but also the main component of sclera. Calcium plays a major role in enhancing the tenacity of sclera.

and

supplementary foods: shrimp skin, kelp, sesame paste, Nostoc flagelliforme, milk and products, beans and products, walnuts, melon seeds, etc. Vegetables containing less oxalic acid should be selected and an appropriate amount of vitamin D should be supplemented to increase the absorption of calcium.

zinc: zinc can enhance the sensitivity of optic nerve, participate in the composition of retinol reductase in liver and retinal cells, and directly affect the metabolism of vitamin A and the role of retinoaldehyde. Therefore, zinc deficiency can affect the operation of vitamin A in the body, hinder rhodopsin synthesis and weaken dark adaptability. In addition, when zinc is insufficient, rhodopsin synthesis in cone cells will also be impaired. So as to affect the color discrimination function of cone cells. Therefore, zinc should be supplemented when vitamin A is supplemented.

and

supplementary foods: oysters, lean meat and hard fruits, golden needle, mustard, broccoli, agaric, mushrooms, preserved apricots, fresh dates, etc.

and

selenium: among a variety of human tissues and cells, the selenium content of eyes is the highest, which is the maintenance
