What factors have led to the rapid rise in myopia incidence in China? In the opinion of experts, the excessive use of electronic devices is the main reason why teenagers wear eyeglass mart.

"Environmental factors are a very important incentive, less outdoor activities, high-intensity, continuous looking close, some children play mobile phones every day, looking at the iPad for more than an hour, bad reading, pen holding habits will lead to myopia." Wu Xi told reporters.

She stressed that people's lifestyles have changed a lot nowadays, and some parents often show their children electronic products in order to prevent their children from crying, but prolonged exposure to such devices can cause damage to children's eyesight.

"In particular, some parents will let their children look at electronic products in the car, and look at electronic products in a dim and shaking environment, which is more damaging to their children's vision." Wu Xi said.

She told reporters that the visual development of children under the age of 2 is not completely fixed, and they should not be exposed to electronic equipment, and bad stimulation will promote rapid myopia of children. After the age of 2, preschool children can watch for up to half an hour a day, and primary school students can normally watch electronic devices for up to 40 minutes a day.

In addition, in the opinion of experts, the degree of awareness of children and parents about the dangers of myopia also needs to be further improved.

"Once myopia is irreversible, and adolescent developmental myopia is caused by the growth of the eye axis, with the growth and development of the body, the degree of myopia in children will increase." If a child develops myopia at an early age, they are more likely to develop high myopia as an adult." Fu Jing reminded.

Fu Jing said that myopia is not a small matter, because it affects not only vision, but also a whole eye disease, "more than 600 degrees of high myopia, the risk of suffering from glaucoma, cataracts, retinal detachment is much higher than ordinary people." And that's something that neither glasses nor laser therapy can fix."

The government is concerned about the high incidence of myopia

In fact, the prevention and treatment of myopia has also been paid attention to at the national level. For example, after the founding of the People's Republic of China, China pioneered eye exercises to protect young people's eyesight, which played a positive role.

In 2016, in order to effectively control the incidence of myopia in children and adolescents in China, the National Health and Family Planning Commission, the Ministry of Education and the General Administration of Sport jointly issued the Guiding Opinions on Strengthening the Prevention and Control of Myopia in Children and Adolescents.

The "Opinions" clearly encourage and advocate students to regularly participate in outdoor activities, actively participate in physical exercise, especially table tennis, badminton and other sports beneficial to the exercise of the eye muscle, maintain correct reading and writing posture, reduce the use of close proximity to the eye for a long time, reduce the use of electronic video products, ensure adequate sleep and balanced nutrition.

In addition, the "Opinions" also stressed that the establishment of a sound eye health exercise system, twice a day eye health exercise time into the class schedule, and organize students to seriously do eye health exercises. Ensure that students' daily physical activity time is not less than 1 hour, and urge students to participate in outdoor activities during recess time. It is necessary to effectively reduce the burden of students' homework, do not increase the teaching hours at will, do not occupy holidays, weekends and winter and summer holidays to organize students' classes, and make arrangements for students' homework time.

"It should be stressed that protective factors such as outdoor exercise can only play a limited role, and the most important thing is to avoid excessive eye use and prolonged exposure to electronic devices to develop healthy eye use habits." Fu Jing said that on the one hand, schools should let children go out to do more exercise during recess, and on the other hand, they should play a good role in publicity and education to let children know the serious harm of myopia.
