Many teenagers are not myopic before school age, but their eyesight has been declining since primary school and junior middle school, and some students have decreased sharply. The reasons are usually explained by children's more homework, eyesight fatigue and improper reading and writing posture after school, but the adverse impact of classroom lighting on Teenagers' eyesight is ignored.
At present, the rate of juvenile myopia remains high, and the "sin" of classroom lighting can not be ignored.
The main reason why classroom fluorescent lamps affect eyesight is the "flicker" of lamps. This high-frequency flicker is easy to fatigue the eyes. In order to see words clearly, teenagers often unconsciously bury their heads lower, which naturally causes or aggravates myopia. In addition, the flashing lights will cause another kind of damage to the eyes when they are forced to adapt - astigmatism.
Learning under the stroboscopic light source will cause eye fatigue, pain and serious damage to the visual system. Especially in the classroom where students have classes, fluorescent lamps are widely used for lighting, and we should pay more attention to the flickering phenomenon of lamps. Because the fluorescent lamps in ordinary classrooms are white and bright, people often feel that the light intensity is enough, but in fact, it is harmful to the eyes of teenagers Harmful.
The way to solve the stroboscopic hazard of fluorescent lamps in the classroom is to select classroom eye protection lamps that meet 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, etc.) choose "Huahui lighting"!
