Recently, we received the opinions of Guangdong Basic and Applied Basic Research Fund Committee, and the acceptance conclusion of the project that research on the effectiveness of artificial simulation of natural light sources in delaying the progression of myopia in school-age children was formally approved. The expert group said: This project has great industrial application prospects and good clinical promotion and application value.

The main purpose of this project is to evaluate the effectiveness of artificial natural light in preventing myopia in primary school children., Foshan Second People's Hospital, and Guangdong Cosio Lighting Co., Ltd. jointly carried out the Study on the effectiveness of artificial simulated natural light sources in delaying the progression of myopia in school-age children (application code: FS0601). The project was successfully shortlisted in the Guangdong Basic and Applied Basic Research Fund Foshan Joint Fund project application guide.

The study adopted the overall randomization method. With the support of Chancheng District Education Bureau, 1,840 students from 39 classes in 4 primary schools in Foshan City participated in this study. The full randomization method was adopted, and the classes were grouped according to 1:1 random control. 1840 students from four primary schools in Foshan were divided into groups. The control group used conventional light sources, and the intervention group used simulated healthy natural light sources with special health chips made by Cosio. The results of three years of observation showed that the cumulative myopia incidence in the control group was 26.4%, and that in the intervention group was 21.2%; the myopia progression in the control group was 0.81D, and that in the intervention group was 0.63D; the axial length of the control group increased by 0.77mm, and that in the intervention group was 0.72mm, with significant differences between the two groups. The results showed that among 8-year-old students in Foshan, China, the use of artificial natural light in the classroom can reduce the incidence of myopia compared with conventional classroom light; the results of the red light combined with OK lens treatment study showed that after one year of observation, the axial length of the red light combined with OK lens group increased by -0.024mm, and the axial length of the OK lens treatment group increased by 0.265mm. The research conclusion showed that red light combined with OK lens treatment can effectively control the progression of myopia in children.

After tracking and comparing nearly 1,840 students in the past three years, the project concluded that the use of light health lamps that simulate natural light sources can reduce the three-year incidence of myopia in children and adolescents by 5.2%.

The project report also states that the results of this study are close to the expected results. The reason for this is that in the past, the LED light sources in classrooms were obviously lacking in red light, while in this study, the artificial simulated natural light source is rich in red light, which is crucial for the prevention and control of myopia. At the same time, after nearly a million years of continuous evolution, humans have adapted to the existing natural environment. The human eye is an optical receptor. After continuous evolution, under the action of natural light, the human eye has completed emmetropization. Therefore, the natural spectrum is more suitable for the emmetropization of the human eye and is more in line with the laws of nature. The potential mechanism needs further study.

Why is the red light spectrum so important for children and adolescents? Relevant medical experts pointed out in a speech titled Prevention and Control of Myopia in Adolescents: From Research Evidence to Clinical Practice that light energy treatment of myopia, as a new treatment option, has been applied and tested in medical clinical experiments and can achieve the goal of controlling children's myopia. Effects of myopia in adolescents. The light energy treatment plan for myopia uses low-intensity, single-wavelength red light or near-infrared light in the range of 630-1000nm to irradiate myopic eyes twice a day for three minutes each time, thereby increasing the choroidal metabolic rate of the eye and reducing the scleral hypoxia rate. In other words, the lack of red light spectrum will lead to hypoxia in the sclera of the eyes, resulting in myopia. Therefore, the red light spectrum is particularly important for children and adolescents.

The high prevalence of myopia among Chinese children remains high. The results of this study will provide a new way to prevent and control myopia among children in my country, and prevent and control myopia among children without affecting students' learning. The biggest innovation of this study is to change the outdoor to indoor, and it also opens up the application of light in the health field. In this study, one of the researchers, Professor He Mingguang, initiated a multi-center study on red light control of myopia. The results showed that repeated low-intensity red light can effectively delay the progression of myopia in children. The results of this study have been published in many SCI papers; the red light treatment instrument developed has been launched on the market; this study provides a safe, effective, simple, easy and economical new way for the prevention and control of myopia, and at the same time opens up the application of light in the health field, with broad market application prospects in the future; this study has also greatly promoted the research and development of the Sunshine Classroom, which will be a new way to prevent and control myopia.
