At 2:30 pm on August 11th, Yu Cun, deputy chairman of the Ophthalmology Branch of the Ningbo Medical Association and the dean of Ningbo Boshi Ophthalmology Hospital, became a health lecture hall, and shared the tricks and experiences of adolescent myopia prevention and control online with netizens.

Cold knowledge newborns have 1000 degrees long vision

In recent years, Yu Cun has found in the clinic that parents now pay more and more attention to their children's vision, especially preschool children, and the long -distance reserves have become a must -ask vocabulary for parents.

Yu Cun said that for children, hyperopia reserves are a more important indicator, which refers to the consequences of visual development in the process of visual development. The newborn's eyeballs are small, and the length of the eye shaft does not reach the level of adult. At this time, the eyes of the newborn are in a state of hyperopia, with 1,000 degrees of hyperopia. This is a physiological hyperopia, which is also called "hyperopia reserve". Then with the growth and development, the degree of remoteness of the eyes gradually decreased and rose to face.

He emphasized a concept: "We are talking about face-to-face, not zero degrees, but referring to 75 degrees of eloquence-50 degrees of myopia." When the child's vision is higher than that of myopia 50 degrees, it is a true myopia.

In order to master the child's vision progress, Yu Cun suggested that parents establish refractive development files for their children. "The child starts at the age of 3 to 3, and regularly checks the vision, refractiveness, and the axis of the eye every six months. For the first time, it also includes corneal curvature and fundus examination." Visual development is a dynamic process. The specific situation of each child's specific situation There are differences. Establishing refractive development files can monitor children's vision development. Once there are myopia signs, they can intervene in time. He suggested to check in the same hospital in order to observe the changes in all data.

Yu Cun said that the reasons for myopia include environmental and eye habits and other reasons, and inheritance accounts for very important factors. "Pathological myopia is also commonly known as 'high myopia', which is mainly caused by genetic. High myopia is above 800 degrees, and the number of years after the age of 18 will continue to deepen. If both parents are highly myopia, the children must also be highly myopia."

He also mentioned the difference between genetic genes in races: "An international survey data shows that Jews are the easiest to myopia, followed by Asians, and Africans have the lowest incidence of myopia."

Attopic efficacy discounts prepared by yourself

Yu Cun's Ningbo Both Eye Hospital undertakes the vision screening project of the campus in Haishu District. During the twice a year, more than 23,000 students conducted vision examinations, and each child will get a report form. Some parents see that "100 degrees myopia" on the report will go directly to the glasses shop to match the mirror, but in fact, the screening degree is only used as a reference for the mirror, and a comprehensive inspection must be combined.

He suggested that children over the age of 12 can get more accurate data after fast -doccoli. A younger child can drip Atto's pupils. "Sandworthiness is the effect of optometry in the case of ciliary muscle paralysis to achieve the effect of pupils."

Yu Cun reminded not to everyone who is not suitable for Atropine. "Atropine has a history of sixty or seventy years in the treatment of myopia, it is currently the only drug to treat myopia. However, it has a certain degree of complications for special groups." The people of myopia can not see clearly; some people recover slowly, and the next day still have symptoms of light, and even decreased vision; some people will have allergic reactions, red eyes and itching; others will rebound, accelerate myopia, and accelerate myopia. Essence

Therefore, low concentration products come into being. "Attop products with a concentration of 0.01%are called low concentration Atto, and 0.1%is a high concentration of Atto." Yu Cun explained that low concentration Atto also uses useful prevention and control of myopia, and the side effects are relatively small. The first drop before going to bed at night, the next day, I can recover, and the rebound after stopping the medicine is also small.

Recently, low -concentration Atropine eye drops have been suspended from online sale, and you need to buy it with prescriptions after taking a doctor for offline hospitals. However, in the comment area of ​​the live broadcast platform, netizens still have a lot of questions about Atropine. Some people ask: Can you arrange the high concentration of Adoupin to a low concentration by yourself? Will the same effect be produced?

Yu Cun said: "Commodity eye drops (from high concentration to low concentration) are not only through simple dilution, but also a variety of additives, preservatives and other additions. At the same time , The effect of the medicine and the factory of the factory by the hospital is 10%different. If the family configuration is configured, the effect will be weaker. "

He also reminded that the first month of Adins will be reviewed, and it can be reviewed every 3 months after normal.

Guests on -site demonstration standard sitting posture

At the moment of the summer vacation, Yu existed at the live broadcast site to demonstrate the standard sitting position for the majority of netizens to achieve the development of effectively preventing myopia.

He said that when writing and reading, keep the eyes with reasonable eyes and correct heads, insist on "one foot, one punch and one inch", that is, the eyes are one foot from the book (about 33 cm), the chest is one punch from the table (about 10 cm), and the chest is one punch (about 10 cm), and the chest is one punch (about 10 cm). The finger of the pen is one inch (about 3 cm) from the pen tip. Do not lie on the table or lying on the bed, on the sofa, let alone read a book in the marching carriage.

Compared with electronic screens, paper reading materials have relatively small damage to the eyes. Reading posture is not positive, and the eye time is too long, which can cause eye fatigue. Pay attention to rest in time when reading, and the longest time is not more than 40 minutes.

Now our lives are inseparable from electronic products, and sometimes even some homework needs to be completed on electronic products. How long is the most suitable iPad and computers?Yu Cun suggested that you should rest in time to watch the electronic screen. It is recommended to watch the screen for 20 minutes, and look up at least 20 seconds out of 20 feet (6 meters), that is, the "20-20-20" formula.Children under the age of 3 avoid contact with electronic products. Preschool children use as little electronic products as possible. Children under 6 years of age should not be able to exceed 25 minutes every day. The daily entertainment screen time of adolescents does not exceed 1 hour.
