What should we eat to protect our eyes? In daily life, we must pay attention to protecting our eyes, because the eyes are the windows of our hearts and the most important organs of our human bodies. There are many ways to protect our eyes in daily life. Here are some ways to protect your eyes.

What to eat to protect your eyes? 1 1, vitamin a.

Vitamin A, also known as retinol, plays an important role in the formation of human vision. It is involved in the synthesis of rhodopsin in retina. If vitamin A is insufficient, the adaptability of eyes to dark environment will decrease, and in severe cases, it will lead to night blindness.

The content of vitamin A in animal liver, cod liver oil, roe, whole milk, whole dairy products and eggs is high. Carotene can also be converted into vitamin A in human body, so it is called provitamin A. Vitamin A is rich in green vegetables and yellow vegetables, fruits such as spinach, leeks, pea seedlings, alfalfa, green peppers, sweet potatoes, carrots, pumpkins, apricots and mangoes.

2. Calcium

Calcium is the "protector" of eye tissue. Calcium deficiency in the body will not only reduce the elasticity of retina, increase the pressure in lens and lengthen the anterior and posterior diameter of eyeball, but also cause degenerative diseases of cornea and ciliary muscle, which will easily lead to decreased vision or myopia.

Milk, beans, fungi, dried fruits and seafood are rich in calcium, which is beneficial to the absorption of calcium when eaten with vitamin D.

3. Trace elements selenium, zinc and chromium

Trace elements such as selenium, zinc and chromium can improve the function of eye tissue and prevent vision loss.

Foods rich in selenium include animal liver, eggs, fish, shellfish, soybeans, mushrooms, asparagus, shepherd's purse, carrots and so on. Foods containing more zinc include liver, kidney, seafood, milk, cereals, beans and hard fruits. Foods containing more chromium include beef, black pepper, brown rice, corn, millet, coarse flour, brown sugar, grape juice, edible fungi and so on.

4, vitamin C.

Vitamin c can weaken the damage of light and oxygen to the lens of the eye, thus delaying the occurrence of cataract. Foods containing vitamin C include persimmon pepper, tomato, lemon, kiwi fruit, hawthorn and other fresh vegetables and fruits.

5. Macroalgae

Kelp contains 1/3 mannitol in addition to iodine. There is a thick layer of "frost" on the surface of dried kelp, which is mannitol in kelp. Mannitol has diuretic effect, which can reduce intraocular pressure and has a good effect on the treatment of acute glaucoma. Other seaweeds such as Undaria pinnatifida also contain mannitol, which can also be used as an auxiliary food to treat acute glaucoma.

6. Coarse grains and fresh vegetables

Finally, eat more coarse grains and fresh vegetables and less sweets and sweets. Vitamins B and C in coarse grains and fresh vegetables have protective effects on eyes.

What should I eat to protect my eyes? Food to protect your eyes.

1, avocado

Avocados are common fruits in tropical areas. This kind of fruit has obvious protective effect on people's eyes, and it is the best choice to protect them, especially for those office workers who often face computer work. Eating more avocado in daily life can improve the anti-radiation ability of eyes and reduce the harm of electromagnetic radiation to people's eyes.

Step 2: carrots

Carrot is also a kind of common food that can protect human eyes, and its protective effect on human eyes is extremely obvious, because carrot not only contains vitamin A, but also contains rich carotene, which can be converted into vitamins as soon as possible after entering the human body. A can directly act on human optic nerve and retina, prevent the decline of optic nerve function and enhance retinal function. It can improve people's ability to do things in the dark. Eating carrots often can not only keep their eyes healthy, but also prevent night blindness.

Step 3: eggs

Eggs are a kind of home-cooked food that people often eat when nourishing their bodies. At the same time, it is also a healthy food that can protect human eyes. Because egg yolk is rich in lutein and zeaxanthin, there are some important nutrients similar to carotene. People can absorb these nutrients as soon as possible after eating eggs, which can prevent cataracts and macular degeneration and is of great benefit to maintaining people's eye health.

4. Chrysanthemum tea

The protective effect of chrysanthemum tea on human eyes is also very obvious. People can soak it in water to clear the liver and improve eyesight, improve the radiation resistance of eyes, relieve eye fatigue and prevent vision loss. In addition, drinking chrysanthemum tea often in water can clear the liver and improve eyesight, relieve people's eye fatigue and reduce the incidence of cataract.

Let me introduce so many top ten foods that protect your eyes. In addition to the above, broccoli, soybeans, blueberries, mulberries and so on. , is a common ingredient in life, can protect the human eye, has excellent protection effect on the human eye, and can be eaten frequently in daily life.

The eyes are the windows of the soul and the bridge between people and the outside world. Moreover, in modern life, people watching mobile phones with computers for a long time will do some harm to their eyes, so the most effective way to protect their eyes is to drink tea. So what kind of tea can protect your eyes? Want to know this knowledge, you can look at the following introduction of tea that is good for your eyes.

What kind of tea to drink to protect your eyes

1, chrysanthemum tea

Drinking chrysanthemum tea in moderation can protect eyes, because chrysanthemum tea is rich in vitamin A, which is an important substance that directly acts on human optic nerve. It can prevent people's optic nerve function from declining, enhance people's retinal function and improve the visual ability of eyes. In addition, chrysanthemum tea can also clear the liver and improve eyesight, relieve eye fatigue and prevent people's eyes from swelling and pain due to excessive liver fire.

2. Gouqi tea

Lycium barbarum tea is also a kind of health tea that can protect human eyes, because Lycium barbarum is rich in carotene and vitamins, and also contains some polysaccharides. It can nourish liver and kidney, clear liver, improve eyesight, improve the visual ability of human eyes, and relieve dry eye, dry eye and eye fatigue. In addition, drinking Lycium barbarum tea can improve the anti-radiation ability of human eyes, which is especially suitable for people who face computer work for a long time.

Introduce tea that is good for eyes

1, cassia seed tea

Cassia seed tea is a kind of traditional Chinese medicine health tea, and it is also a kind of health tea with many benefits for human eyes. Because cassia seed itself is a Chinese herbal medicine that can improve eyesight, clear liver and clear heat, it can nourish the optic nerve and relieve eye fatigue. Drinking cassia seed tea regularly can prevent vision loss and reduce the harm of electromagnetic radiation to human eyes.

2. Green tea

Green tea is a very common tea in life, and it is also good for people's eyes. Because green tea is not only elegant and sweet, but also rich in antioxidants and vitamin C, people can clean up free radicals in the body after brewing and drinking green tea, and can also regulate the endocrine function of the human body and improve the function of the central nervous system. It can keep human eyes healthy and prevent vision loss and eye fatigue.

After reading the above introduction, you can know what kind of tea to drink, which can protect your eyes and what kind of tea is good for your eyes. Later, when you want to protect your eyes, or often face computer work, you can drink more of these health teas. Insisting on soaking them in water can protect eyes and maintain eye health.

What should I eat to protect my eyes? 3 What is good for eyes?

1, vitamin B 1

Vitamin B 1 plays an important role in the development and normal maintenance of vision. If vitamin B 1 is lacking in the body, it will weaken the resistance of the optic nerve system of the eyes and easily form myopia. Foods rich in vitamin B 1 include all kinds of green leafy vegetables, beans, lean meat and seafood.

2. vitamin a

If vitamin A in the body is insufficient, the regeneration of rhodopsin will be slow and incomplete, which will affect vision and seriously cause night blindness and dry eye. The best food sources of vitamin A are various animal livers, cod liver oil, fish eggs, eggs and so on. Followed by carrots, spinach, amaranth, red sweet potatoes, pumpkins and other vegetables.

3, vitamin C.

Vitamin c can reduce the damage of light and oxygen to the lens of the eye. Foods containing vitamin C include persimmon pepper, tomato, lemon and kiwi fruit.

4. Calcium

Calcium deficiency will not only affect bone development, but also reduce the elasticity of the developing eyeball wall-sclera, increase the internal pressure of the lens, and lengthen the anterior and posterior diameter of the eyeball, thus leading to myopia. Foods containing more calcium mainly include milk and its products, shellfish, bone meal, beans and bean products, egg yolk, dark green vegetables and so on.

5. Zinc

We know that children have a bad appetite and need zinc supplements. In fact, zinc also has many effects on their eyesight. Zinc participates in the metabolism and transportation of vitamin A in the eyes, maintains the normal tissue state of retinal pigment epithelium and maintains normal visual function. Foods containing more zinc include oysters, meat, liver, peanuts, wheat and miscellaneous grains.

Methods of protecting children's eyesight

1, following the principle of 20-20-20. La wolford, an optometrist in Florida, once emphasized that every 20 minutes, you should overlook the scenery at 20 feet (about 6 meters) for more than 20 seconds. Overlooking can make the ciliary muscle in a relaxed state. Of course, just let the child rest his eyes for 40 minutes!

2. Correct eye posture. Don't let children play with mobile phones, lie down, lean, lie down and read while walking. These eyes will also affect their eyesight. Parents should pay attention to cultivating their children's correct sitting posture, and try to keep their backs straight when standing and sitting.

3, usually blink more. Blinking can stimulate our eyes to secrete more liquid to lubricate them. Every time we blink, a new tear film will form in our eyes. Blinking fewer times, insufficient secretion of tear film, will make eyes dry and sour.

4. supervision. Let children do eye exercises and blink exercises 1~2 times a day.

In addition, it is also a good way to protect your eyes to have regular eye examinations and follow the doctor's advice to correct them.

Children amblyopia

At present, the causes of amblyopia are mostly classified by vonNoorden, that is, amblyopia is divided into the following five types: strabismus amblyopia, ametropia amblyopia, form deprivation amblyopia and congenital amblyopia.

1, strabismic amblyopia, strabismus occurs, both eyes can't look at the specified target at the same time, and the object image of the same object can't fall on the corresponding points of both eyes' retinas at the same time, thus causing diplopia. In addition, when strabismus occurs, the targets of binocular macular fixation are different, and because of the fusion function, the brain center overlaps two completely different targets of binocular macular fixation, thus causing confusion.

2, ametropic amblyopia, ametropic amblyopia is more common in middle and high hyperopia and astigmatism, because in the critical period of visual development (from birth to 3 years old) and sensitive period (before 6 years old), the object image on the retina is always blurred, and the brain center receives this vague stimulation for a long time, which can form amblyopia for a long time.

3, anisometropic amblyopia. Unequal diopter of both eyes is called anisometropia. Most of them are hyperopia, with spherical lens difference of ≧ 1.50D and cylindrical lens difference of ≧ 1.0D. Due to excessive anisometropia, the clarity and size of the object image falling on the retina of both eyes are different (the difference of diopter of both eyes is1.0d, and the difference of object image size of both eyes is 2%). The visual center is easy to accept the visual conduction of the clear object image of the eye, but inhibits the object image from the larger eyeball with ametropia. Over time, the object image of eyes with higher diopter is suppressed, forming amblyopia.

4. Form deprivation amblyopia. In the critical period of infant's visual development (before the age of 3), amblyopia caused by corneal lesion, congenital cataract, complete ptosis and eye disease is called form deprivation amblyopia. Because it happens in the critical period of baby's visual development, it will cause extremely serious damage to vision.

5. congenital amblyopia. At present, the pathogenesis is not clear. VonNoorden speculated that newborns are prone to macular retinal hemorrhage and visual path hemorrhage due to urgent labor, dystocia and midwifery. It may affect the normal development of visual function and lead to amblyopia. However, through clinical observation and follow-up, it is found that retinal hemorrhage in the macula of newborns is absorbed quickly and will not cause amblyopia.

astigmatism in children

Astigmatism is mainly caused by the change of corneal curvature of eyes.

The cornea, also called "dark circles", is a window in front of the eyeball. It is not only smooth and transparent, but also a complete hemisphere. Its main function is to gather light through light, make it enter the pupil and reach the fundus retina, become the focus, and then reflect it to the brain, so that people can see the outside world clearly.

Therefore, when the curvature of the hemisphere cornea changes, like an uneven lens, and the surface is uneven and irregular, the external light cannot form a focus on the retina, but spreads in all directions, making the brain's understanding of external objects vague, resulting in astigmatism. This kind of astigmatism is medically called irregular astigmatism. Because the corneal curvature changes too much, it is difficult to correct it with glasses.

There is also a kind of astigmatism called regular astigmatism, which is caused by the curvature of cornea in a certain direction inconsistent with its vertical direction. It has many types, including simple hyperopia astigmatism and simple myopia astigmatism; There are compound hyperopia astigmatism, compound myopia astigmatism and mixed astigmatism, which are mostly caused by different refractive power of cornea and coexist with myopia or hyperopia, and can be corrected with glasses.

There are two internal causes of irregular astigmatism caused by uneven and curved cornea, one is congenital inheritance and the other is acquired corneal disease. If corneal ulcer or trauma occurs, scar will be produced after healing, resulting in uneven and curved cornea. Regular mild astigmatism generally does not affect vision, but discomfort such as eye fatigue may occur.

Children myopia

First of all, the biggest reason is nothing more than using your eyes for a long time. Especially now there are so many electronic products that children can't put it down for hours; However, long-term close eye use will increase intraocular pressure and lengthen the axial length, leading to myopia.

Secondly, outdoor sports are seriously inadequate. It is considered that increasing outdoor exercise can increase the time of retina receiving light, and light stimulation is beneficial to the synthesis and release of dopamine in retina, shortening the length of eye axis and preventing myopia.

In addition, diet will also affect your eyesight! Long-term lack of vitamin B 1, calcium and other trace elements will affect the normal development of eyeball and lead to eye diseases such as myopia. Another study shows that people who like sweets, love frying, hate coarse grains and have a partial eclipse have a significantly higher myopia rate than those who have a reasonable diet.

To sum up, children's eyes need good maintenance and must stay away from electronic products. Playing computer and mobile phone for a long time is very harmful to eyes, resulting in many children suffering from myopia, amblyopia, astigmatism and other eye diseases. We must prevent eye diseases in advance and learn to protect our eyes better.
