China News Service, Wenzhou, November 12 (Fan Yubin and Ge Mingrui) "The current situation of myopia in China is extremely severe, showing a trend of younger age and high growth. The proportion of high myopia continues to increase, and pathological changes continue to increase, which has seriously threatened the visual health of Chinese society. "On November 12, Qu Jia, director of the Department of Ophthalmology and Optometry of Wenzhou Medical University and general dean of the Wenzhou Medical University Eye and Optometry Hospital Group, said.
On the same day, the Science Conference on Myopia Prevention and Control 2021 Boao Myopia Forum (China Eye Valley) was held in Longwan District, Wenzhou City, Zhejiang Province.
At the meeting, version 3.0 of the Boao Declaration on Myopia Prevention and Control was officially released.
Industry experts discussed the hotspots and difficulties in the progress of myopia prevention and control, the latest multi-dimensional myopia prevention and control research and management viewpoints, scientific prevention and control measures revealed by basic scientific research on myopia, and early clinical intervention methods.
The World Health Organization research report shows that China has 600 million myopia patients, and it has become the world's largest myopia country.
What is more worrying is that the overall myopia rate of Chinese children and adolescents exceeds 50%, and the proportion of high myopia is also on the rise.
In order to reverse this situation, in 2018, led by the Ministry of Education of China, the United Nations National Health Commission and other 8 departments issued the "Implementation Plan for the Comprehensive Prevention and Control of Myopia in Children and Adolescents", and the prevention and control of myopia has become a national strategy.
"With the development of various tasks, the overall rate of myopia in China has dropped significantly, and the ability to prevent and control myopia has been significantly improved. The basic situation of overall results has been initially demonstrated." Qu Jia said.
Boao Declaration on Myopia Prevention and Control Version 3.0: Follow the "Double Reduction" Policy
Before myopia prevention and control became a national strategy, the Boao Declaration on Myopia Prevention and Control issued at the Boao International Vision Forum in 2017 clearly put forward the advocacy of myopia prevention and control and included it in chronic disease management.
In 2019, the Boao Declaration on Myopia Prevention and Control Version 2.0 was released, proposing the establishment of scientific and efficient myopia screening, health management and safe treatment of children and adolescents.
"The latest version 3.0 of the Boao Declaration on the Prevention and Control of Myopia actively responds to the'double reduction' policy and advances with scientific development and the implementation of comprehensive myopia prevention and control." said Lu Fan, director of the National Eye Disease Clinical Medical Research Center, myopia There are 8 items in the Boao Declaration on Prevention and Control Version 3.0.
According to Lu Fan, in order to reduce the burden on the eyes of children and adolescents while reducing the burden on their studies, the Boao Declaration on Myopia Prevention and Control Version 3.0 proposes to "create a healthy environment for eyes."
The creation of "good environment with eyes" covers both hardware and software.
The former includes measures to improve the lighting and lighting conditions of school classrooms and homes, and to equip children and adolescents with desks and chairs suitable for their height. The latter includes intensified sports activities to ensure that students have 2 hours of outdoor activities a day.
In addition to closely following the "double reduction" policy, the Boao Declaration on Myopia Prevention and Control Version 3.0 also includes "comprehensively carry out screening and filing to realize the informatization of prevention and control work", "highly value early intervention to avoid serious myopia development", and "effectively promote appropriate technologies." "Ensure the standardization of diagnosis and treatment safety", "Extensively organize scientific education, expand the popularization of prevention and control knowledge", "vigorously strengthen scientific research, and promote scientific prevention and control measures".

Experts talk about prevention and control of myopia: ports need to be moved forward, younger age needs to be curbed
"In 2020, the overall myopia rate of children and adolescents in China is 52.7%, which is 0.9% lower than the 53.6% in 2018. This basically achieves the expected target of a 0.5% reduction in the overall myopia rate of children and adolescents in the Comprehensive Implementation Plan for the Prevention and Control of Myopia in Children and Adolescents." Qu Jia said.
The effectiveness of myopia prevention and control does not mean that related work can be done once and for all.
Statistics show that the overall myopia rate of Chinese children and adolescents dropped to 50.2% in 2019.
However, by 2020, due to the impact of the new crown pneumonia epidemic, Chinese children and adolescents spend more time on online learning and reduce outdoor activities. The overall rate of myopia has rebounded, and the problem of younger age of myopia is still prominent.
"Preschool age is a critical period for refractive development of the eye, and parents are the main responsible persons. We must take the initiative to carry out vision screening during the newborn's health examination." "The focus of prevention and control for 3-6 years old is to control the time of watching TV and playing with mobile phones. When Lv Fan released version 3.0 of the Boao Declaration on Myopia Prevention and Control, he proposed to "promote the advancement of prevention and control ports to curb the aging of myopia."
When a child enters the school, the responsibility for myopia prevention and control also needs to be shared by the school and the teacher.
How to implement the visual health monitoring of school students to achieve precise prevention and control?
As the host of the Science Conference on Myopia Prevention and Control, Wenzhou has accumulated rich experience in this regard.
According to Ni Tong, Member of the Party Committee of Wenzhou Education Bureau and Deputy Governor Xue Xue, since June 2019, the city has carried out 6 myopia surveys of primary and secondary school students, covering nearly 1.1 million students in 1333 primary and secondary schools in Wenzhou. The census rate is higher than 99.5%.
"'City-wide, over one million, and high-efficiency' are the characteristics of Wenzhou's myopia census, and the visual health digital file is an efficient application of related vision data." Ni Tong said.
Using the power of big data, Wenzhou has established an information platform for the prevention and control of myopia in children and adolescents. The visual health digital files of “one file for a lifetime, one file follows people, and cannot be modified” are not only convenient for the government, schools and other departments to accurately grasp the rate of myopia and correction rate. The above data can also provide parents with access to vision data and timely early warning.
Since its establishment in August 2018, the Wenzhou children and adolescents myopia prevention and control information platform has sent warnings and medical guidance to 240,000 students who have early onset, rapid development, and high risk of myopia.
The overall myopia rate of Wenzhou primary and secondary school students dropped from 54.5% in 2018 to 51.94% in 2020, which is the lowest in Zhejiang Province.
"The myopia survey of children and adolescents needs to use integrated and intelligent equipment to collect key parameters such as vision and eye refractive power, and through the establishment and optimization of the myopia prevention and control information system to achieve automated myopia survey and archiving." Qu Jiaru looks forward to Chinese children and adolescents. The future of myopia census.
Looking at China, relevant deployments have already begun.
In June 2021, the Ministry of Education of China issued the "Notice on Doing a Good Job in Reporting the Main Information of Regular Eyesight Monitoring for Primary and Secondary School Students", proposing to effectively implement the student health examination system and the vision monitoring system, and require schools in all regions to pass each year in the spring and autumn semesters. The national student physical health reporting system reports the results of visual acuity monitoring for primary and secondary school students.
