According to the latest data of the Ministry of Education, the myopia rate of primary school students in China is 34%; 65% for junior high school students; 83% of senior high school students showed a significant upward trend in the decline of their eyesight. In addition to the use of electronic products, incorrect sitting posture, heavy learning burden, congenital factors and other reasons that cause the decline of students' vision, school classroom lighting has a responsibility that cannot be ignored.
According to a survey, primary and secondary school students in China spend about 60% of their time in the classroom every day. When the lighting and lighting conditions in the classroom are insufficient, the light is too dark, glare, blue light, and color temperature are too high and low, the refractive system of the eyes will change over time, leading to myopia.
The key problems that affect the health of classroom lighting environment mainly focus on six aspects: blue light, stroboscopic, glare, color temperature, color rendering and illuminance. Blue light and stroboscopic light are easy to cause vision damage, and at the same time, they can induce many diseases, such as cataracts, migraines, and brain damage. Glare is one of the important causes of visual fatigue. The unreasonable light distribution of lamps and lanterns is easy to reduce the visual conditions of object visibility. The color rendering of color temperature is an important indicator to improve visual clarity. Too low color rendering index will cause visual color distortion, affect the primary and secondary school students' eye recognition of object color, and cause mental fatigue.
As an important place for learning and activities, the lighting environment without eye protection will have an impact on students' eyesight. In the lighting design of the classroom, because the lighting layout in the classroom is unreasonable or bare bulbs and tubes are used, direct glare is generated. If the blackboard lamp is not used properly, students will feel uncomfortable when they see the text on the blackboard because of the reflected glare.
How can primary and middle school students prevent myopia? The classroom lighting should not be ignored in the prevention and control of myopia. It is necessary to create classroom lighting that meets the national standards. It is recommended that all primary and secondary schools and institutions (including public school classroom lighting, private school classroom lighting, private school classroom lighting, experimental school classroom lighting, educational institutions), classroom lighting OEMs and licensors choose the "Huahui Lighting" brand!
