Didn't buy a desk to cause myopia? !

Even in times of economic downturn, optical shops will never lack business. It’s common to sell a pair of ordinary frames to thousands, and it’s worrying. In the myopia army, young people are the main force! According to the report of relevant research institutions, 90% of adolescents have various degrees of scoliosis, oblique shoulders, hunchback, myopia and other problems caused by sitting posture during the growth and development stage. The incidence of myopia and scoliosis in primary and middle school students in China There is a clear upward trend. According to a recent survey, the incidence rate of myopia in our pupils is 22.78%, and that of middle school students is 55.22%. What is even more shocking is that there are reports in the country that more than 30 adults have been blinded by high myopia. Myopia, scoliosis and psychological problems have constituted an obstacle to the healthy development of adolescents.

One of the incentives for myopia turned out to be the most inconspicuous desk in the house. Why do ordinary desks become the "catalyst" for teenage myopia? And listen to the small series.

1. The height of the traditional desk chair is fixed. The child's feet are suspended, the feet have no fulcrum, and the upper body is easy to squat forward. In addition, due to the gravity of the calf, the thigh will be squeezed with the seat of the chair, and the thigh is easy to numb. The child will move unconsciously and often.

2. The table of the traditional desk is straight. When the child learns, the two elbow joints will be exposed on the outside of the table. The small arm will squeeze with the edge of the table. The small arm will be sore and the child will instinctively put the two elbow joints. Put it on the table, the upper body will naturally lie on the desktop.

3, the desktop of the traditional desk is flat, the child is forced to bow when reading and writing, causing the child's cervical spine to be sore.

4, the traditional chair's sitting surface is too large, the child can not rely on the back of the back when reading and writing, it is easy to cause back pain.
