Abstract: hyperopia diopter and accommodation determine whether hyperopia is present. Mild hyperopia can be overcome with a small amount of adjustment.

Slightly more severe hyperopia or slightly insufficient accommodation, so far and near vision are not good., Have you ever heard of ametropia? Are there any ametropic children around you? Ametropia is a common ophthalmic disease, which includes hyperopia, myopia and astigmatism. Nowadays, there is an urgent situation of children’s ametropia. Therefore, we should understand the symptoms and prevention of ametropia in children, and stay away from ametropia eye diseases. Today, we will introduce some knowledge about children’s ametropia., I. symptoms of children’s ametropia. 1. If children have mild or moderate myopia, they have no other symptoms except blurred distant objects. When working close, they can see small targets without adjustment or with less adjustment, but feel convenient. However, in high myopia, the target distance is very close when working, and the two eyes are too inward, which will cause excessive use of internal rectus muscle and visual fatigue., 2. The degree of hyperopia diopter and the strength of accommodation determine whether there is hyperopia. Mild hyperopia can be overcome with a small amount of adjustment. Both far and near vision can be normal, generally asymptomatic. Such hyperopia is called recessive hyperopia. Slightly heavier hyperopia or slightly insufficient adjustment, so the far and near vision are not good. The remaining part that can not be fully compensated by regulation is called dominant hyperopia, and the total combination of recessive hyperopia and visual is called total hyperopia. Hyperopia is prone to visual fatigue due to long-term tension., 3. If children have blurred handwriting, dry eyes, heavy eyelids, fatigue, eye pain and headache after reading and writing for a long time, the symptoms will obviously reduce or disappear after a short rest. Such symptoms are generally the most common in the afternoon and evening. Even nausea and vomiting in severe cases. This phenomenon is the manifestation of eye fatigue., II.

have you ever heard of ametropia? Are there any ametropic children around you? Ametropia is a common ophthalmic disease, which includes hyperopia, myopia and astigmatism. Nowadays, there is an urgent situation of children’s ametropia. Therefore, we should understand the symptoms and prevention of ametropia in children, and stay away from ametropia eye diseases. Today, we will introduce the relevant knowledge of children’s ametropia one by one.
1. Symptoms of ametropia in children
1. If children have mild or moderate myopia, they have no other symptoms except blurred distant objects. When working close, they can see small targets without adjustment or with less adjustment, but feel convenient. However, in high myopia, the target distance is very close at work, and the two eyes are too inward, which will cause excessive use of internal rectus muscle and visual fatigue.
2. The diopter of hyperopia and the strength of accommodation determine whether hyperopia is present. Mild hyperopia can be overcome with a small amount of adjustment. Both far and near vision can be normal, generally asymptomatic. Such hyperopia is called recessive hyperopia. Slightly heavier hyperopia or slightly insufficient adjustment, so the far and near vision are not good. The remaining part that can not be fully compensated by regulation is called dominant hyperopia, and the total combination of recessive hyperopia and visual is called total hyperopia. Hyperopia is prone to visual fatigue because it is in a state of tension for a long time.
3. If children have blurred handwriting, dry eyes, heavy eyelids, fatigue, eye pain and headache after reading and writing for a long time, the symptoms will obviously reduce or disappear after a short rest. Such symptoms are generally the most common in the afternoon and evening. Even nausea and vomiting in severe cases. This phenomenon is the manifestation of eye fatigue.
2. Prevention of children’s refractive error
1. Educate children to read and write correctly, do not form the habit of leaning on the table, and do not read while lying down or taking the bus.
2. When reading or writing, the distance between books and eyes should be kept at about 30 cm.
3. The light should be sufficient and soft. Don’t study in direct sunlight. The light source should be in the front left.
4. To prevent eye muscle fatigue, the learning time should not be too long. It is appropriate to take 40 minutes at a time, rest for 10 minutes, look at distant objects or do eye exercises.
5. If you suffer from ametropia, you should wear glasses of appropriate degree in time.
III. food therapy
to alleviate children’s ametropia 1. Pig liver soup
raw materials: 100g pig liver, 2 eggs, Douchi, scallion, salt and monosodium glutamate.
and
methods: 1. Wash the pig liver and cut it into pieces; 2. Put some water in the pot and cook over low heat until the liver is cooked; 3. Add black bean sauce and scallion; 4. Then beat in the eggs; 5. Add salt and monosodium glutamate to taste.
2. Fried pork liver with Chinese wolfberry
raw materials: 50g Chinese wolfberry, 250g pig liver, a little lard, salt, cooking wine and monosodium glutamate.
and
methods: 1. Soak Lycium barbarum in warm boiled water for 2 hours and remove it; 2. Slice pig liver and mix well with salt and cooking wine; 3. Stir fry with lard until cooked. Add medlar and stir fry until cooked. Add monosodium glutamate and bring out of the pot. Share a meal.
when children’s refraction is not being treated, they can choose the recipe with pig liver as raw material.
1. Do not write or read in too strong or too dark light; 2. Lying in bed or in a car or boat or walking is reading; 3. Don’t read books with too small and dense fonts and unclear handwriting; 4. Don’t write with a light pencil; 5. Don’t watch TV too long.
genetic factors are important causes of ametropia. There are many reasons for ametropia, among which genetic factors are very important. Of course, unreasonable eye use can not be ignored. Especially in modern society, study and workWith the increase of pressure, people have too much contact and dependence on computers and television, resulting in all kinds of refractive errors.
and
babies who learn to walk too early are more likely to suffer from ametropia. The visual development of
and
infants is not perfect after birth, and crawling can make infants see what they can see, which is conducive to the healthy development of infants’ visual acuity; On the contrary, if babies learn to walk too early, because they can’t see the distant scenery in front of them, they will try to adjust the diopter and focal length of their eyes to look at the scenery, which will cause a kind of fatigue damage to the baby’s delicate eyes. Repeated times will damage their eyesight and form ametropia, which is better than myopia without glasses.
the above is a detailed introduction to the symptoms and prevention of ametropia in children. I hope it will be of some help to the majority of children and friends. At the same time, we should also pay attention to eye hygiene, protect our eyes, stay away from eye diseases such as ametropia, and take off our glasses as soon as possible to make our eyes brighter!
