Eye care is inseparable from nutrition

Abstract: the eyes are inseparable from water. The transparent cornea is most afraid of dryness, so people constantly wipe and moisturize the cornea with the tears secreted by the lacrimal gland. Dry hot air in spring and summer or dry air in autumn and winter, long staring time on TV and computer screen, severe dehydration and lacrimal gland atrophy in the elderly are unfavorable to cornea and even suffer from dry eye; Dry eye is easy to be complicated with conjunctivitis, keratitis, dacryocystitis and other eye diseases., People often say, “take care of your eyes…” we can see the position of your eyes in people’s minds. But do you really understand how to take care of your eyes? What nutrition does the eye (eye food) need? What does it like? Hate what?, The eyes can’t live without water. The transparent cornea is most afraid of drying, so people constantly wipe and moisturize the cornea with the tears secreted by the lacrimal gland. Dry hot air in spring and summer or dry air in autumn and winter, long staring time on TV and computer screen, severe dehydration and lacrimal gland atrophy in the elderly are unfavorable to cornea and even suffer from dry eye; Dry eye is easy to be complicated with conjunctivitis, keratitis, dacryocystitis and other eye diseases., In addition, the intraocular lens is also a living structure immersed in aqueous humor. It is undergoing continuous metabolism. The circulating aqueous humor plays an important role in its metabolism and maintaining transparency. The lack of water in the elderly (elderly food) human body is one of the reasons for the turbidity of crystals. Therefore, both young and old should develop the adaptation of drinking more water, including white water, tea and drinks; Pay attention to prevent diarrhea, vomiting, massive sweating and dehydration; Fortunately, long-time viewing of the screen and close reading caused dry eyes due to staring. When your eyes are dry, don’t always rub your eyes, but close your eyes to rest or see a doctor. The eyes can be properly maintained and moistened, which can improve the dryness and discomfort of the eyes., Protein and vitamin (vitamin food) a the cornea, lens and retina of the eye need protein (protein food) and vitamin A. when lacking, it will cause cataract, night blindness and keratopathy. To develop the adaptation of eating lean meat, fish and eggs, vegetarians (vegetarian food) should not forget dairy and soybean products, because they are rich in protein and high quality; Often supplement cod liver oil or eat foods rich in vitamin a such as chicken liver, sheep liver, pig liver, carrots, garlic seedlings, coriander, rape and spinach. At the same time, eat food oil, because vitamin A can only be absorbed by dissolving in oil (oil food)., Supplement vitamin C the content of vitamin C in human eyes is 30 times higher than that in blood. With the increase of age, the content of vitamin C decreases significantly, and the lens is malnourished, which will cause lens degeneration over time; Vitamin C can weaken the damage of light oxygen to the lens and prevent the formation of senile cataract. Although vegetables (vegetable food) and fruits (fruit food) are rich in vitamin C. Bring your own household fruit pulp machine to make fresh fruit juice, which is better to drink. It not only replenishes water, but also replenishes vitamins., B vitamins are important substances involved in the metabolism of nerve cells including optic nerve, and play a role in caring for eyelids, conjunctiva and cornea. When lacking or insufficient, it is easy to make eyes dry, bulbar conjunctival congestion, eyelid inflammation (rotten edge), photophobia, blurred vision, vision fatigue, and even optic nerve inflammation. Foods rich in B vitamins include peanuts, beans, millet, animal viscera, meat, eggs, fish, rice bran, peas, etc. Vitamin B12 is very important for the formation of peripheral myelin sheath of nerve fibers. Natural vitamin B12 can only be obtained from animal foods, so vegetarians need to eat more soybean milk or supplement vitamin B12.,

people often say, “take care of your eyes…” we can see the position of your eyes in people’s mind. But do you really understand how to take care of your eyes? What nutrition does the eye (eye food) need? What does it like? Hate what?

eyes are inseparable from water. The transparent cornea is most afraid of dryness, so talents constantly wipe and moisten the cornea with tears secreted by lacrimal glands. Dry hot air in spring and summer or dry air in autumn and winter, long staring time on TV and computer screen, severe dehydration and lacrimal gland atrophy in the elderly are unfavorable to cornea and even suffer from dry eye; Dry eye is easy to be complicated with conjunctivitis, keratitis, dacryocystitis and other eye diseases.

in addition, the intraocular lens is also a living structure immersed in aqueous humor, which is undergoing continuous metabolism. The circulating aqueous humor plays an important role in its metabolism and maintaining transparency. The lack of water in the elderly (elderly food) human body is one of the reasons for the turbidity of crystals. Therefore, both young and old should develop the adaptation of drinking more water, including white water, tea and drinks; Pay attention to prevent diarrhea, vomiting, massive sweating and dehydration; Fortunately, long-time viewing of the screen and close reading caused dry eyes due to staring. When your eyes are dry, don’t always rub your eyes, but close your eyes to rest or see a doctor. So that the eyes can be properly maintained and moisturized, which can improve the dryness and discomfort of the eyes.

protein and vitamin A (vitamin food) the cornea, lens and retina of the eyeball all need protein (protein food) and vitamin A. when lacking, it will cause cataract, night blindness and keratopathy. To develop the adaptation of eating lean meat, fish and eggs, vegetarians (vegetarian food) should not forget dairy and soybean products, because they are rich in protein and high quality; Often supplement cod liver oil or eat chicken liver, sheep liver, pig liver, carrots, garlic seedlings, coriander, rape, spinach and other foods rich in vitamin A. at the same time, eat some food oil, because vitamin A can only be absorbed by dissolving in oil (oil food).

supplement vitamin C. The content of vitamin C in human eyes is 30 times higher than that in blood. With the increase of age, the content of vitamin C decreases significantly, and the lens is malnourished, which will cause lens degeneration over time; Vitamin C can weaken the damage of light oxygen to the lens and prevent the formation of senile cataract. Although vegetables (vegetable food) and fruits (fruit food) are rich in vitamin C. Bring your own household fruit pulp machine to make fresh fruit juice, which is better to drink. It not only replenishes water, but also replenishes vitamins.

B vitamins are important substances involved in the metabolism of nerve cells including optic nerve, and play a role in caring for eyelids, conjunctiva and cornea. When lacking or insufficient, it is easy to make eyes dry, bulbar conjunctival congestion, eyelid inflammation (rotten edge), photophobia and poor visionMixed vision, fatigue, and even optic nerve inflammation. Foods rich in B vitamins include peanuts, beans, millet, animal viscera, meat, eggs, fish, rice bran, peas, etc. Vitamin B12 is very important for the formation of peripheral myelin sheath of nerve fibers. Natural vitamin B12 can only be obtained from animal food, so vegetarians need to eat more soybean milk or supplement vitamin B12.

and

don’t forget that trace elements (trace element foods) such as zinc, cadmium, molybdenum and selenium also participate in the synthesis of various substances in the eyes and regulate their physiological effects. Zinc deficiency hinders the operation of vitamin A, and also causes retinal rhodopsin synthesis disorder and impaired dark adaptation. Foods rich in zinc include oysters, lean meat, etc; When cadmium is insufficient, it will hinder the effect of insulin regulation, increase blood glucose (blood glucose food), increase the osmotic pressure of eye lens aqueous humor, and increase the diopter, resulting in myopia. Foods rich in cadmium include beef, coarse flour, mushrooms, grapes (grape food), etc; Selenium participates in the activities of eye muscles and pupils, and is an important element to maintain vision. If the daily intake of selenium is less than 50 mg, vision will be hindered after a period of time. Foods containing more selenium include fish, poultry, Chinese cabbage, radish, garlic, etc; Molybdenum is an important nutrient in the iris of the eye. Foods containing more molybdenum include radish, soybean, lentil, etc.

careful use of aspirin can prevent senile cataract. The level of amino acids in patients with senile cataract is often increased, and tryptophan is the only amino acid (amino acid food) that can bind to plasma protein. Tryptophan and its metabolites combine with lens protein and become brownish yellow substances, which deposit in the lens to form cataract. Aspirin competes with tryptophan and blocks its binding with crystal protein, so as to reduce the degree of tryptophan in crystal. If the dosage of water soluble aspirin is less than 100 mg per day, it can not cause gastrointestinal symptoms, but also achieve the goal of preventing cataracts and blood viscosity. People with glaucoma bias are spared the use of atropine mydriasis drugs to avoid hindering eye water circulation; Sometimes with some hormone drugs, there is a feeling of headache and eye swelling, which may also be a harbinger of glaucoma.

and

avoid strong light. Strong ultraviolet light, especially sunlight, is more harmful to the crystal. The longer the irradiation time, the greater the possibility of suffering from cataract. When going out, especially when traveling and swimming, you should wear a big brimmed hat and dark sunglasses to shield ultraviolet rays. Old people don’t wear sunglasses to catch up with the fashion. Although dim light is also bad for the eyes, moderation is better.

prevent hypoxia in recent years in diabetes research found that due to the lack of normal nutrition needs, eye tissue is often in an “starvation state” of oxygen deficiency, and transparent lens gradually becomes cloudy and unclear, as if it is blocked by a layer of white membrane and can not see clearly. It is called “diabetic cataract” in medicine. Hypoxia will block the iris and anterior chamber angle (outlet of atrial flow), hinder the discharge of intraocular aqueous humor, and increase the intraocular pressure, forming “secondary glaucoma”; Hypoxic diabetes also causes retinal capillary hemangioma, new blood vessels and exudates, that is diabetic retinopathy. Therefore, people with diabetes should actively treat diabetes (diabetes food) to prevent a series of eye diseases caused by hypoxia.
