Some schools carry out lighting transformation to prevent and control juvenile myopia original title: some schools carry out lighting transformation to prevent and control juvenile myopia bright learning environment is conducive to protecting students' eyesight recently, the national lamp quality supervision and Inspection Center (Zhongshan) (hereinafter referred to as the "national lamp center") was entrusted by a school in the western district to evaluate the lighting effect of its classrooms, According to the requirements of relevant standards, the inspectors of the national lamp center measured the illumination and illumination uniformity in the blackboard, classroom desktop and other areas

it is found that some classroom lighting in the school has problems such as insufficient illumination and uniformity of the desktop and blackboard. According to the relevant person in charge of the national lamp center, according to the requirements of the implementation plan for comprehensive prevention and control of myopia among children and adolescents issued by eight departments including the Ministry of education, some schools in Zhongshan have carried out lighting transformation

the myopia rate of primary school students is more than half

according to a research report organized by the World Health Organization, at present, China has 600million myopia patients, and the myopia rate of teenagers ranks first in the world. The myopia rate of high school students and college students has exceeded 70% and is increasing year by year. The myopia rate of primary school students is also close to 40%

what about Zhongshan? Doctors from Zhongshan Eye Center affiliated to Sun Yat sen University once conducted a survey on the prevalence and incidence rate of myopia among primary school students in Sun Yat Sen city several years ago by using the wind path switching method to introduce the temperature into the test area. At that time, 28 public primary schools were selected from Sun Yat Sen City, and a total of 1670 people participated in the survey. All the selected students were 6~13 years old

the survey results show that the myopia rate of primary school students in Zhongshan City is 51.7%, which means that every two primary school students in Zhongshan have one myopia. The myopia rate of boys is about 45%, and that of girls is about 57.3%. The prevalence of myopia in girls is significantly higher than that in boys. At the same time, with the increase of age, the prevalence of low myopia decreased, and the prevalence of moderate myopia and high myopia increased gradually

myopia is the most important cause of poor vision in adolescents. According to niexin, director of Ophthalmology at Zhongshan Humanity Hospital, the causes of myopia are closely related to genetic background and environmental factors

"poor reading and writing posture, poor optometry and glasses: Good evening on December 12, mismatched desks and chairs can cause optical defocused myopia." Niexin said that the high incidence of juvenile myopia is closely related to today's living environment. "Nowadays, changes in people's living environment, limited open space in the city, early entry of children into educational institutions, long-time and close-up homework of teenagers, poor reading and writing habits and less outdoor activities can all lead to myopia of teenagers in the development stage. However, juvenile myopia, which is rising year by year, has become a public health problem."

unqualified lighting environment

is an important factor leading to children's myopia

research shows that environmental light sources for learning and home are closely related to children's visual health, and unqualified lighting environment is an important factor leading to children's myopia. Reading and writing shall be carried out in an environment with good lighting and sufficient lighting. In 2018, read the value indicated by the passive pointer on the indicator dial (the display value of the digital display device). The Ministry of education and other eight departments jointly issued the implementation plan for comprehensive prevention and control of myopia among children and adolescents, proposing to include the prevention and control of myopia among children and adolescents and the overall myopia rate in the government performance assessment indicators. By 2030, the myopia rate of primary school students will be reduced to less than 38%, that of junior middle school students to less than 60%, and that of senior high school students to less than 70%

the plan defines the prevention and control measures to be taken by families, schools, medical and health institutions, students and relevant government departments. Among them, the school requires to improve the visual environment: improve the teaching facilities and conditions, encourage the purchase of standard adjustable desks and chairs and sitting posture orthotics, provide students with a learning environment that meets the requirements of eye hygiene, strictly follow the construction standards of ordinary primary and secondary schools and secondary vocational schools, implement the lighting and lighting requirements of classrooms, dormitories, libraries (reading rooms), and use lighting equipment that is conducive to visual health. The school classroom lighting health standard compliance rate is 100%...

it is learned from the national lamp center that the center actively responds to relevant policies, relies on professional testing technology and ability, establishes the testing ability to meet the whole project of classroom lighting and lighting in accordance with GB hygienic standard for lighting and lighting in primary and secondary school classrooms, obtains relevant qualification recognition, and issues authoritative testing reports for government departments and enterprise customers, In case of non-compliance, timely provide rectification suggestions according to the standard requirements

through the actual measurement of classroom lighting, the National Lighting Center has further mastered the classroom lighting status of primary and secondary schools in Zhongshan City, providing reliable technical support for the implementation of the implementation plan for comprehensive prevention and control of children and adolescents' myopia and the protection of adolescents' visual health in Zhongshan City

some schools in Zhongshan have carried out lighting transformation

according to the relevant person in charge of the National Lighting Center, according to the requirements of the implementation plan for comprehensive prevention and control of myopia among children and adolescents issued by the Ministry of education and other eight departments, some schools in Zhongshan have carried out lighting transformation, and the main problems in the lighting of some classrooms are the illumination and uniformity of the desktop and blackboard

"generally speaking, when the lamps in the classroom need to be maintained and replaced (generally when the newly installed lamps are attenuated to 80% of the luminous flux), the average illumination of the whole blackboard needs to reach more than 500lx, and the illumination in the darkest area of the blackboard cannot be lower than 80% of the average." The person in charge suggested that in the process of family study and work, local lighting could be increased to enhance the illumination of the study area. The brightness of the scene in the field of view of study and work should be as uniform as possible, and there should be no too bright objects or areas. If it is illuminated at night, it is recommended to use a light source with a warm color

in addition, there are a wide variety of functional lamps for students in the market. Some claim to be able to prevent myopia, and some can provide natural light. How should citizens choose? The person in charge suggested to purchase lamps with CCC compulsory certification and CQC energy saving certification marks. "CQC energy saving certification is a voluntary certification. Enterprises that pay more attention to quality generally take the initiative to apply for CQC energy saving certification to prove that their products can reach a higher quality level."
