According to statistics, the incidence of myopia among Chinese students is among the highest in the world. In addition to the heavy burden of schoolwork, the lighting conditions of the classrooms are not up to standard. Primary and secondary school students in our country spend about 8-10 hours a day in the classroom. If it is a boarding school, they spend more time in the classroom. Some studies have shown that poor educational lighting is the main cause of students' vision loss. one of the reasons.

High stroboscopic educational lighting, which causes the pupils of the sphincter to expand and contract, causing eye fatigue and decreased vision. At present, 220V, 50Hz fluorescent lamps are commonly used as lighting sources in schools, causing the lamp to flicker 100 times per second. Learning under constant light sources, the visual system needs to constantly adjust the size of the eye pupil to protect the stability of the retina light Sexuality and imaging clarity, learning in this light environment for a long time, makes the pupil sphincter fatigue due to overuse, light eye fatigue, and serious damage to the visual system.

     The color rendering index is low, and the spectrum of ordinary fluorescent lamps is incomplete, which will cause color loss and color cast, far below the national standard Ra≥80, and the poor color reduction ability of lighting fixtures will directly affect children's color discrimination ability.

    The color temperature of education lighting is high, and the light is white. National standards stipulate that classrooms should use 3300k-5500k color temperature lights. Most school classrooms have a color temperature of about 6500K, and the light is white, which can easily lead to excitement and fatigue, and cause myopia for a long time.
