Shock! Nearly half of primary school students suffer from myopia. It is the culprit

Abstract: heavy schoolwork is the first killer leading to the sharp increase of students’ myopia rate. Exposure to sunlight can promote the retina to release a chemical substance, slow down the increase of axial length of the eye and avoid the development of high myopia.

according to the recent report of Shenzhen business daily, the myopia rate of primary school students in Shenzhen is 47.58%, which means that about half of primary school students have become myopia. In fact, not only in Shenzhen, myopia has swept primary and secondary schools across the country.

according to statistics, in cities across the country, four fifths of teenagers suffer from myopia, of which one fifth is high myopia, that is, objects 16 cm away can’t be seen clearly. Among them, the number of primary school students with myopia increased the fastest, 40% of them were myopia, and the myopia rate was twice that of 2000. The myopia rate in the United States and Germany is less than 10%. What is


that makes myopia sweep through primary and secondary schools all over the country?

is the first killer. Ian, a adolescent health researcher at the Australian National University “The combination of not going out and focusing on close areas (such as writing and reading) further exacerbates the problem. But if children have enough time to be outdoors, they can learn as much as they can without losing their eyesight,” Morgan said


in China, they are usually asked to take a nap after lunch instead of playing outdoors. After dinner, they have to start a long homework time. According to statistics, Chinese children need to do more homework than children in other parts of East Asia. The older the child, the more time he spends indoors. The heavy schoolwork task of


is the first killer leading to the sharp increase of students’ myopia rate. Exposure to sunlight can promote the retina to release a chemical substance, slow down the increase of axial length of the eye and avoid the development of high myopia. However, under the pressure of heavy schoolwork, Chinese children lack outdoor activities for a long time and are exposed to the sun for a short time, which directly leads to the widespread myopia of children.

four serious hazards of myopia in primary school students

1. Drag down learning – pay 30% more effort. The phenomena of blurred vision, dry and sore eyes, difficulty in concentration, emotional irritability and even dizziness caused by

myopia will make children pay 30% more time and mental labor than children with normal vision, Spend more time on study.


2. Drag on Further Education – more than 30 majors are limited to apply for


. Every year, a large number of candidates are rejected by the limited majors because of myopia, involving nearly 30 majors such as electronic information, bioengineering, Medical Pharmacy, flight and navigation technology, which seriously affects children’s life and career planning

3. Degree deepening – develop into high myopia

children are short-sighted, so they are anxious to match glasses, but glasses only have corrective effect, but they have no therapeutic effect. After wearing glasses, the child can see the distance, but when reading and writing at a close distance, the myopia lens aggravates the burden of using the eyes.


4. Heredity – become slaves of glasses for generations. Genetic factors play an important role in the occurrence and development of myopia. Parents are highly myopic, and the proportion of children’s myopia is 100%. If they do not take treatment, they will become slaves of glasses for generations.

four ways to save children’s myopia

in fact, myopia within 300 degrees can be controlled. If not controlled, myopia will generally deepen at a rate of 100 degrees per year until the eyes are set.

The distance between eyes and books should be about 33 cm. At the same time, parents should purchase tables and chairs according to the height of children, so as to ensure the correct writing posture and make the distance between eyes and books meet the correct requirements. When watching TV, people should keep a distance of more than 3 times from the diagonal of the fluorescent screen. Their eyes should rest for 15 minutes every half an hour.
