In recent years, data shows that the myopia rate among adolescents in China remains consistently high, ranking first in the world. There are more and more people with myopia, becoming increasingly young and severe. Research has shown that in addition to frequent use of electronic products and other factors, poor classroom lighting is another major cause of students' visual impairment. About 60% of primary and secondary school students in our country spend their time in the classroom every day. When the lighting and lighting conditions in the classroom are insufficient or too dim, students instinctively approach the books. Over time, it will naturally cause changes in the refractive system of the eyes, leading to myopia.
As long as the lighting in the classroom is bright enough, it is not easy to be nearsighted? This is a cognitive misconception among some schools and parents. In fact, the lighting environment of the classroom should comprehensively consider various factors such as illuminance, glare value, color rendering index, flicker, color temperature, and blue light hazards. Overbright or too dark may cause myopia in students. A truly high-quality classroom lighting should achieve excellent illumination, no glare, high color rendering index, no flicker, moderate color temperature, and no harm from blue light.
To create a healthy and comfortable classroom lighting environment, it is necessary to comply with the relevant standards for classroom lighting renovation. The "Hygienic Standards for Daylighting and Lighting in Primary and Secondary School Classrooms" states that all classrooms should be equipped with artificial lighting, and the average illumination value on the classroom desk should not be less than 300lx, and the uniformity of illumination should not be less than 0.7; The blackboard in the classroom should be equipped with local lighting, with an average illumination value of not less than 500lx and an illumination uniformity of not less than 0.8. The uniform glare value (URG) of the classroom should not exceed 19. Data shows that traditional T8 bracket fluorescent lamps and LED ordinary lamps without glare treatment have glare values greater than 20, causing glare. Studying in this environment for a long time can cause students to feel dizzy and dizzy. The classroom should use a light source with a color temperature of 3300K-5500K.
