Flooded with children and teenagers.
As a result, there are more and more "small glasses".
According to the latest data released by the National Health Commission
The overall myopia rate among children and adolescents in China is 527%
The situation of myopia prevention and control is severe.
And for individuals.
It is inconvenient to wear glasses.
"Shengshi Beauty" is also sealed by glasses.
So. It is important to protect your eyes.
This issue of "Women's Science Popularization Open Class" is invited.
Li Hui, professor of ophthalmology and doctoral supervisor in Beijing
Brought for students.
Lecture on "Strategies for the Prevention and Control of Myopia in Adolescents".
Tell everyone about myopia.
How to "prevent" and how to "control".
Let's take a look.
Primary school is the "first period" of myopia prevention and control
The primary school stage (6-12 years old) is the first stage of myopia prevention and control, and the 6-9 years old is the diamond stage of **. For students with normal vision but high-risk factors for myopia, or insufficient farsightedness reserve, early prevention and key intervention should be carried out. Myopia prevention trilogy: eye behavior, suitable light, outdoor activities.
Develop healthy eye behaviors
Understand the knowledge of scientific eye use and eye protection, and adhere to the 20-20-20 rule. That is, look at electronic products for 20 minutes and look at 20 feet (6 meters) away for at least 20 seconds, so as to effectively prevent eye fatigue and reduce the progression of myopia. Strengthen outdoor activities and physical exercise to reduce students' academic burden;Cultivate and supervise children and adolescents to develop good eye hygiene Xi, so that they can establish eye care behaviors. Build a visually healthy environment
Families and schools reduce the burden of homework and out-of-school training for students, improve lighting conditions, and equip desks and chairs suitable for the height of children and adolescents. ** and communities should increase the dissemination of relevant standards and knowledge. Create a supportive social environment.
Increase outdoor activities during the day
Schools, families and communities work together to reduce the number of children and adolescents who continue to see near each other for long periods of time, and take a variety of measures to provide relevant conditions for children and adolescents and encourage them to engage in outdoor activities. More than 2 hours a day.
The earlier myopia is controlled, the greater the benefit
There are two main influencing factors for myopia:
One is genetic factors. High myopia, genetic factors are more obvious;Low to moderate myopia, caused by a combination of genes and environment;Adolescents with myopia and myopia have a significantly increased risk of myopia, and there is a positive correlation with the degree of myopia of their parents.
The second is environmental factors. For example, more near eye use, less outdoor activities, reading and writing Xi, lighting and nutrition, sleep time, trace elements, use of electronic products, etc., are the main reasons for the high incidence of myopia in children and adolescents.
Data shows that in 2020, the myopia rate of children aged 6-8 years has increased significantly. The younger the age of onset of myopia, the faster the average progression. The study found that 7-year-olds progressed almost twice as fast as 11-year-olds on average.
Children who develop myopia at the age of 7 or 8 years, without intervention, 539% will develop high myopia in adulthood. And high myopia has become one of the leading causes of vision loss.
The earlier myopia is controlled, the greater the benefitThe ultimate goal is to reduce the rate of myopia growth at an age when myopia is growing rapidly, thereby reducing the incidence of high myopia.
Therefore, for children and adolescents who have myopia, it is recommended to go to a medical institution to receive refractive examinations such as medical optometry, so as to make a clear diagnosis and take timely measures to correct it.
How to control the growth of myopia?
Delay the progression of myopia in childrenOne is drug control, and the other is optical intervention.
Medication control is the use of atropine eye dropsThis has reached an expert consensus in the prevention and control of myopia in children and adolescents. Studies have confirmed that 001% atropine eye drops have a good effect on slowing down the progression of myopia, and have the effect of minimal post-drug withdrawal, and at the same time have a cumulative effect on myopia control.
One of the optical interventions is wearing glassesMany people are worried that wearing glasses will make children's myopia deeper and deeper, which is a misunderstanding, and wearing the right prescription glasses in time can obtain clear vision and reduce the development speed of myopia. The second is to wear orthokeratology lenses, that is, OK lensesOrthokeratology is a powerful means of myopia control, but it can only be completed after rigorous judgment by doctors, comprehensive and careful examination, and proper wearing.
In short, drug control + optical intervention, multiple measures at the same time, can curb the rapid progression of myopia to the greatest extent. 
If you want to know more.
Popular science knowledge. Please continue to pay attention to the women's science popularization open class.
Sponsored by the Propaganda Department of the All-China Women's Federation, the "Women's Science Open Course" aims to invite science popularization experts to teach science courses in campuses, science education bases and other relevant places, focusing on a series of topics such as the healthy growth of adolescents and popular science knowledge, and widely disseminated to primary and secondary school students, parents and families across the country. Next, the "Women's Science Popularization Open Class" will also organize more authoritative experts to go into primary and secondary school campuses, streets and communities and other places to hold lectures on a series of topics related to the healthy growth of teenagers, aerospace, scientific knowledge, etc., and record the lecture process into a series of popular science courses, which will be pushed to primary and secondary school students and parents across the country to help everyone take the initiative to learn Xi use scientific knowledge, consciously resist pseudoscience, anti-science and other undesirable phenomena, and arm their minds with scientific ideas. **Propaganda Department of the All-China Women's Federation.
