The situation of myopia in China is worrying, and teenagers are a high incidence group

Abstract: there are two main factors for the high incidence of myopia in adults and adolescents. Internal cause refers to that myopia is affected by genetic factors. If the parents of teenagers are highly myopic, the probability of genetic myopia will be greatly improved. The external cause is mainly the change of eye habit. The time of close eye use is too long and the time of outdoor activities is seriously insufficient.

at present, the problem of ametropia among adolescents in China has become increasingly prominent, and the rate of poor vision remains high, which has seriously affected the healthy development of adolescents in China.

myopia in China is worrying, especially among teenagers.

according to the results of the national survey on students’ physical health, the poor eyesight rates of primary school students aged 7-12, junior middle school students aged 13-15, senior high school students aged 16-18 and college students aged 19-22 are 45.71%, 74.36%, 83.28% and 86.36% respectively, and gradually develop towards younger age.

and

popularize scientific eye knowledge, prevent ametropia and improve eye health awareness have once again become a major focus of health education in China.

and

myopia affect the whole life, and prevention and control cannot be careless. According to the analysis of

and

ophthalmologists, there are mainly internal and external factors causing high incidence of myopia in adolescents. Internal cause refers to that myopia is affected by genetic factors. If the parents of teenagers are highly myopic, the probability of genetic myopia will be greatly improved. The external cause is mainly the change of eye habit. The time for close eye use is too long and the time for outdoor activities is seriously insufficient. The bad eye habits of

and

include the following five aspects:

and

improper eye use methods: too long close eye use leads to eye fatigue, and teenagers will unconsciously approach books. The ambient light of

and

is poor: insufficient indoor lighting and lack of outdoor activities lead to fatigue of human eyes.

wrong eye posture: reading by car or walking will change the distance between eyes and books, increasing the burden on eyes.

and

lack of eye rest: continuous close eye use for a long time is too heavy to ease.

and

external factors: artificial light sources such as electronic product screens emit light, which aggravates eye fatigue. Long term use of electronic products will lead to the occurrence and development of myopia.

and

to sum up, the main reason for the high incidence of myopia among teenagers is improper eye use and insufficient eye protection.

in view of these factors that cause myopia, experts put forward the following eye protection suggestions to teenagers:

develop good eye habits and ensure eye rest time. The appropriate eye distance is 30-35cm. After continuous eye use for 40 minutes, let your eyes rest and look into the distance.

pay attention to the eye environment and sitting posture. Avoid reading in a bumpy car, reading while walking and lying down. When reading, you should choose a suitable desk and chair and sit upright.

and

ensure more than two hours of outdoor activities every day. On the one hand, receiving the stimulation of natural light can return the eyes to the natural state and prevent myopia. On the other hand, increasing outdoor activities also reduces the time of contacting electronic products.

and

establish refractive development files, predict in advance, and conduct regular refractive examination every year to effectively monitor the occurrence and development of myopia. Once myopia occurs, you must go to a professional eye hospital to check the binocular visual function, wear glasses for correction in time and cooperate with the recovery training of binocular visual function. You can also choose Aier corneal plastic lens myopia control technology to more effectively control the development of myopia.
