Symptoms and prevention of ametropia in children

Abstract: if children have mild or moderate myopia, they have no other symptoms except blurred distant objects.

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 degree of hyperopia diopter 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.
