Many parents will try all kinds of ways to restore their children's eyesight when they first find their children's myopia. However, at present, if the child is really short-sighted, there is no way to reverse the development of degrees.

How to distinguish whether the child is really nearsighted?

When the eye has no degree, the distant parallel light enters the eye, just focusing on the retina, and we can see clearly. When looking near, because the light entering the eye is not parallel, the lens in the eye needs to become more convex and have a stronger ability to focus the light on the retina. But the lens becomes convex, mainly depends on the ciliary muscle contraction, that is, the ciliary muscle regulation ability.

Therefore, when the eyes are looking at the distance, they are in a relaxed state; when they are looking near, they need to use adjustment to see clearly. And long-term use of regulatory function, ciliary muscle will always be in a state of contraction, may cause fatigue or spasm. Pseudomyopia is often referred to as the fatigue of ciliary muscle.

How to distinguish true myopia from false myopia?

Answer: mydriatic optometry.

The so-called mydriasis, in fact, is to drop cycloplegic drugs into the eyes, so that the ciliary muscle does not contract. Because these drugs usually cause mydriasis, so the clinical process is called mydriasis.

After mydriasis, optometry is performed. Since the effect of ciliary muscle has been removed at this time, the true degree of the eye can be found out.

If after mydriasis optometry, the child still has myopia degree, that means that the child is really myopia, usually can not be reversed.

What can we do at this time?

Let the children develop slowly. If necessary, they should wear glasses!

There are many kinds of lenses, how do parents choose?

When the child is just short-sighted, most parents will choose to give the child frame glasses. At present, we can simply divide the lens of frame glasses into single light lens, double light lens and progressive multi focus lens.

Single lens

This is the most familiar lens, which has only one focus, including spherical and aspheric design.

In contrast, the curve design of aspheric surface can make the lens thinner and more beautiful, with less aberration and distortion, so the visual quality will be better.

Many parents like to make their children match less degrees. They think that if the degree match is higher, it seems that the degree will rise faster.

However, studies have shown that under correction (i.e. not wearing glasses or not enough glasses) and foot correction (enough glasses) are more likely to slow down the development of myopia.

Therefore, it is recommended that you try to match the degree enough to obtain the lowest degree of the best corrected vision.

Reduce the defocusing lens of peripheral hyperopia

Nowadays, many children are wearing a special kind of lens, which can reduce the defocusing of peripheral hyperopia. They think it can control the development of myopia. What's the matter with this kind of lens?

For ordinary single lens, when the image in the center of the lens just falls on the macular area in the center of the retina, the image focus around the retina actually falls on the back of the retina, that is, the so-called peripheral hyperopia defocusing.

As the focal point falls behind the retina, the compensatory lengthening of the ocular axis will be induced, and the myopia degree will increase by 300 degrees for each 1mm increase of the ocular axis.

Therefore, theoretically, reducing the defocus of peripheral hyperopia can eliminate this inducing factor and control the increase of myopia degree.

This principle is used to control the development of myopia. However, according to the published literature, the effect of reducing the defocusing of peripheral hyperopia by using frame lens is not as good as that of shaping lens.

bifocal lens

The so-called double light, in short, is a pair of lenses with two focal points.

Generally, the upper part of the lens is a normal degree lens, which is used to look far; the lower part is a lens with a certain degree added down, which is used to look near.

For example, when you look far, you are nearsighted by 500 degrees; when you look near, if you add 150 degrees, you become nearsighted by 350 degrees.

The main purpose of this design is to see near, the eye does not need to use adjustment, parallel light can focus on the retina, avoid the fatigue of ciliary muscle, so control the development of myopia.

There are indeed studies that show that binoculars have some effect on myopia control, but long-term wearing is prone to exotropia.

As our eyes are close to each other, adjustment and convergence are related. That is to say, when the eyes are used for adjustment, the eyeballs will converge inside, while wearing binocular glasses, the children's eyes will not use adjustment when they are close to each other, and the eyeballs will not turn inside. If we do this for a long time, it is easy to cause the eyes to deviate outwards and affect the normal eye position.

Therefore, in order to equip children with binocular glasses, it is necessary to add a certain degree of prism to control the normal eye position, which is the current binocular prism.

However, there is a problem with the binoculars. The degrees of the upper and lower lenses vary greatly, so there will be a jump phenomenon when looking at the distance and the near.

The emergence of progressive multifocal lenses solves this problem.

progressive lenses

This kind of lens has multiple focal points, and the design of progressive lens is gradual transition from top to bottom. So it's quite suitable for people with decreased regulation ability, that is, the eyesore.

Wearing a pair of progressive multifocal glasses, you can see far, middle and near. Since there is no obvious boundary between lenses, there will be no jumping phenomenon.

There was a time when progressive multifocal glasses were also recommended for children to wear. It was thought that reducing the adjustment of near sight can control the development of myopia, but at present, the mainstream academic circles do not agree to wear progressive multifocal glasses for ordinary children.

Because it may affect the normal position of the eyes as well as the binoculars. Therefore, in addition to children with implicit deviation, progressive multifocal glasses can be considered, and children with general myopia are not recommended to wear progressive multifocal glasses.

To sum up, for most children, the most important thing is to have mydriatic optometry first, and then to have full correction. The lens and the double prism which can reduce the defocusing of peripheral hyperopia have certain effect on the control of myopia. We can follow the doctor's advice according to the specific situation. However, progressive multifocal glasses are not recommended except for children with implicit inclination.

Nearsighted people are often put on the coat of indifference. In fact, nearsighted people are not indifferent, they just can't see. So, what can myopic people do in daily life to delay the degree of deepening?

With the development of modern high technology, life is full of a variety of electronic products, such as mobile phones, computers, televisions, etc., which have great attraction to people. Long time use of these electronic products will lead to myopia, in addition, unreasonable use of eyes will also lead to myopia, such as lying in bed reading, lying on the table writing homework, etc. So in order to prevent the degree of myopia deepening, we must use the eye reasonably.

1. Pay attention to eye habits. Reading must be in a place with enough light, and the eyes and books should keep a proper distance, not too close. In addition, we need to control the time of fun electronic products. We can't stare at electronic products all day long. A long-term focus will lead to eye fatigue, which will lead to myopia in the long run.

2. Don't overwork your eyes. If you feel tired in your eyes, you must put down the things in your hands and let your eyes have a full rest. When the eyes are tired, you can do eye exercises, or look far away, so that the eyes can be relaxed.

3. Get plenty of sun. According to research, two hours of outdoor sun exposure per day can delay the increase of myopia. This is because the eye secretes a substance called dopamine under the action of the sun, which can delay the increase of myopia. It should be noted that the sun protection work must be done well in the outdoor sun. You can apply some sunscreen products or put on sunscreen clothes to avoid sunburn.

4. Wear cornea shaping glasses. If you want to delay the increase of myopia, you can also wear plastic cornea glasses. This kind of glasses is a kind of special contact lens, which is usually worn at night, and the wearing time is about eight hours. If you wear cornea shaped glasses at night, you don't need to wear glasses during the day. It can meet the needs of eyes during the day. It is a very effective way to delay the increase of the degree by wearing the plastic cornea glasses. It does not need surgery.

If there is any discomfort in wearing plastic cornea glasses, please take off plastic cornea glasses immediately and see a doctor immediately. Cornea shaping glasses are generally suitable for people with myopia degree less than 800 and astigmatism degree less than 100.

If you want to delay the increase of myopia, you can also eat some food that is good for your eyes. People with myopia should not stay up late at night. Staying up late is very bad for your body, especially for your eyes. Every month, it's better to go to a regular hospital to check the light, understand the increase and change of the degree of your eyes, and change your glasses in time.

The college entrance examination is over. We can relax completely! Although the college entrance examination is over, but the protection of our eyesight can never be relaxed. Myopia and bad eye habits are related to a certain extent. In the same way, bad eating habits can also become accomplices to induce myopia. To prevent myopia and keep away from the problems brought by myopia, we might as well start with eating first. These six kinds of food are eye protectors.

1. Vitamin A

Vitamin A plays an important role in the formation of human vision and participates in the synthesis of rhodopsin in retina. Lack of vitamin A will affect the adaptability of eyes in the dark environment, which is manifested as decrease, and even lead to night blindness. The foods with high vitamin a content include animal liver, cod liver oil, roe, whole milk and whole milk products, eggs, etc.

Carotene can be converted into vitamin A in human body, which is also called vitamin a source. Spinach, leek, pea seedling, alfalfa, green pepper, sweet potato, carrot, pumpkin, apricot, mango and other vitamin A sources are more.

2. Calcium rich food

Calcium is also known as the "protector" of eye tissue. If there is a lack of calcium in the body, it will lead to the decrease of the elasticity of the eye retina, the increase of the pressure in the crystalline body, the lengthening of the anterior and posterior diameter of the eyeball, and may also lead to the pathological changes of the cornea and ciliary muscles, so as to easily lead to vision loss or myopia.

The foods rich in calcium include milk, beans, fungi, dried fruits and marine products, and they can be used with vitamin D to help calcium absorption.

3. Foods rich in vitamin C

Persimmon pepper, tomato, lemon, kiwifruit, hawthorn and so on are rich in vitamin C. vitamin C can weaken the damage of light and oxygen to the lens of the eye and delay the occurrence of cataract.

4. Trace elements

Microelements mainly include selenium, zinc, chromium, etc., which can improve the function of eye tissue and prevent vision loss. Animal liver, egg, fish, shellfish, soybean, mushroom, asparagus, shepherd's purse, carrot, etc. contain more selenium; liver, kidney, seafood, milk, cereal, beans, hard fruit, etc. contain more zinc; beef, black pepper, brown rice, corn, millet, coarse flour, brown sugar, grape juice, edible fungus, etc. contain more chromium.

5. Kelp

In addition to iodine, mannitol contains one third of the "status" in kelp. There will be a layer of "white frost" on the surface of dried kelp, namely mannitol. Its effect is to reduce intraocular pressure, so it is helpful for the treatment of glaucoma. Seaweed products, such as Undaria pinnatifida, also contain mannitol, which is an adjuvant treatment for glaucoma.

6. Coarse grain and fresh vegetables

Most of the time, we advocate eating more coarse grains and fresh vegetables, because they contain vitamin B and vitamin C, which can play a role in eye protection.

Don't pay attention to these three points. Look out for myopia

1. Too sweet

Eat too much sweets, will consume a lot of vitamin B1 in the body, but also reduce the calcium in the body, weaken the elasticity of the eye wall, induce myopia.

2. Eating too well

The reason why eating too well is not good. This is because eating too well for a long time, especially for children, will lead to the lack of trace element chromium in their body, which will lead to the lens becoming convex, the diopter increasing, and induce myopia.

3. Eating too soft

Eating too soft is not good, it is reported that too little hard food intake is also one of the causes of juvenile myopia.

Nowadays, people use computers and mobile phones more and more. For a long time, playing and working without limit will cause our eyes to feel itchy, slight pain, vision loss and blurring. Therefore, it is very important to properly maintain our eyes. How to protect our eyes in daily life?

1. Take buckwheat skin, mung bean skin, black bean skin, cassia seed and chrysanthemum. The medicine is finely mixed and evenly mixed. It is put into a cloth bag to make a pillow. The pillow is covered with plastic bag and taken off at night. We have a clear vision.

2. This prescription is fumigated and washed with liquid medicine for external use. It can directly affect the eyes, increase the metabolism of the eyes, promote the blood circulation, and is very beneficial to the health care of the eyes. Wash Mungbean and chenjing rice and put them into the pot. Add 1000ml of water. Cook them into congee in high heat and low heat first, then put them into liver slices. The liver is cooked. Take it three times a day.

3. 2 chicken livers, 100g rice, a little salt. Chop the chicken liver and cook it with rice as porridge. When it is cooked, mix in salt and take it twice in the morning and evening. This prescription can increase the vision, especially for night blindness and people with dazzling eyes.

4. 120 g of Cistanche deserticola, 60 g of Morinda officinalis, 60 g of chrysanthemum and 60 g of Lycium barbarum. The 4 flavours are dried and dried together, and the white wax is used as a pill, such as Wutong. Take 15g / day, twice a day, dilute salt and boiled water. Our side is full of essence and bright moon, which is suitable for fainting.

5. This is the Cixi recipe proposed by Zhang Zhongzhi, a royal doctor of Qing Dynasty. It can be used as a daily health care prescription for eyes. 9 g for chamomile, 9 g for frost mulberry leaf, 3 G for mint, 1.5 g for antelope horn tip, 9 g for raw land and Prunella vulgaris. Pan fried, smoked and washed.

Daily eye care tips

1. When reading, whether it is physical books, e-books, computer screens, mobile phones or tablets, the light should be sufficient and have enough distance. It is recommended to take a rest every 30 minutes, close your eyes or look at distant scenery.

2. More outdoor activities, such as playing ball, and looking at distant scenery. Because outdoor activities involve focusing far and near and moving focus in all directions, the eye muscles can take the opportunity to relax and tighten.

3. You should wear sunglasses for outdoor activities. It is ideal to have UV400 degrees to completely block the UV, and you can also wear a hat, especially when the sun is strong at 12 noon. It is found that people who work outdoors and are exposed to sunlight but do not take corresponding eye protection measures will suffer from cataracts, wing flesh, macular degeneration and other problems earlier than ordinary people.

4. Do not rub your eyes often. Wash your hands frequently to reduce infection.

5. It's easy for computer workers to dry their eyes for a long time. When they need it, they can drop preservative free artificial tears and blink in the distance. Sometimes, when we focus on the computer screen, the number of blinks will decrease and lead to dry eyes. We found that the lower part of the cornea was very dry. The reason was that the eyelid was opened before it was completely covered, so that the tears were not enough to moisten the eyes.

6. If you find eye spots, blindfold, eye pain or dry eyes, you should see an ophthalmologist to check them out. If you have red eyes, you have the chance to have an eye infection, you must seek medical advice as soon as possible. You should not buy eyedrops randomly.

These prescriptions listed above will relieve our tired eyes to a certain extent. In addition, the most important thing is that when we read books or use computers in our daily life, we should adjust our suitable luminosity, and always wear sunglasses and other protective measures for outdoor sports.
