If false myopia is matched with glasses, it will cause excessive load on the child's eyes, resulting in heavier myopia development, so children must do mydriatic optometry before the glasses.

When mydriasis optometry, which is good, fast and slow? Fast powder is generally suitable for myopic children over the age of 7, when the child's cycloid muscle adjustment force is moderate, the use of fast powder can obtain a more accurate value, generally 6 hours can be recovered, will not affect normal life and learning.

Slow powder is suitable for children under 7 years of age, children's small ciliary muscle regulation ability is relatively strong, must use such as atropine eye gel such slow powder.

Slow-release drugs can fully dilate the pupil, ensuring accurate refraction, but it takes about three weeks to recover. If mydriasis is not sufficient, it will affect the results of optometry. Therefore, preschool children mydriasis and optometry are recommended to use slow dispersion.

How should we slow down the myopia process of children in daily life?

Nowadays, people attach great importance to physical health, but often neglect the health of eyes. Especially young parents, often take the mobile phone to the baby as an "electronic nanny", which is the most harmful to the child's eyes.

Because children's eyes are still in the stage of development, the stimulation of premature electronic products, so that children are always in a close overregulation state, early formation of myopia, which is very painful.

Experts pointed out that genetic and environmental factors in the occurrence of myopia accounted for about 50%, in the current can not change the genetic factors, change environmental factors and active treatment become the main way to prevent and cure myopia students.

There are several things we can do to prevent it in our daily lives.

1. Change the way you play. Modern urban children's games are mainly indoor entertainment, such as TV, personal toys, game consoles, computers and so on. Parents should encourage their children to change the way they play and do more outdoor activities.

2. Pay attention to eye hygiene. Usually we should educate children to pay attention to eye health, pay attention to the distance between the eyes and the book when reading, the posture should be correct, and can not read while lying down or walking. Pay attention to the lighting of reading to be sufficient, reading and writing for 40 minutes should rest, vision, can not be too addicted to game consoles, TV.

3. Pay attention to eye care. Urge children to do eye exercises every day, crystal exercises (rhythmical rapid alternating look far and near), self-acupressure (eye Ming, Zhuzhu, fish waist, Sizhu empty, Chengwei, four white, etc.).

4. Play table tennis and fly kites often. Simple myopia occurs in about 10 years old, the main cause of myopia is eye fatigue.

When playing table tennis, the eyes take the ball as the goal, constantly adjust the movement up and down, can improve the tense state of the ciliary muscle, make it relax and contract; The external eye muscle can also be constantly active, promoting blood circulation to the eye tissue, improving nutrient supply, thereby improving eye sensitivity, eliminating eye fatigue, and preventing myopia.

Kite flying, as an activity that enables people to see far gradually, can also effectively relieve eye muscle spasms caused by long-term eyes looking close.

5. Vision loss should be treated at the hospital in time. Early diagnosis and treatment can delay and control the development of myopia.

6. Pay attention to eating habits and nutrition, avoid chromium, calcium and other trace element deficiency. The health care of the normal function of the eye and the renewal of aging tissues need protein as the basic material for proliferation and repair. Should pay attention to the intake of some protein-rich foods, such as meat, fish, eggs, soybeans and so on.

Vitamins are necessary for the growth and maintenance of healthy physiological functions, and are also indispensable from the perspective of maintenance of visual function.

Foods rich in vitamin A include cod liver oil, animal liver, butter, milk, etc. Lean meat, peanuts, beans, potatoes, green leafy vegetables and so on are rich in vitamin B1, eggs, beans, animal liver, milk, bacteria and algae foods contain vitamin B2, vitamin D is mainly distributed in animal liver, eggs, milk and other foods.

In addition, Chinese wolfberry also has the effect of brighteningeyes, it can be cooked with an appropriate amount of longan, or cooked with pig liver to take, not without benefit to the health of eyes.
