Have you ever had this feeling? In the evening when the sky is getting late or the moment when the lights in the evening self-study classroom are turned on, you always feel a little dazzling and dazzling, and feel a little dizzy.
In fact, this is because direct exposure fluorescent lamps are widely used in most traditional classroom lighting lamps, that is, the lamp tube is exposed outside the lampshade, there is no barrier in front of the lamp tube, and the light of eye protection lamp directly shines on the students' eyes. The glare and dizziness of the light are due to the naked glare, stroboscopic, blue light and other visual damage problems of the fluorescent tube to the eyes, of which the glare is the reason why we feel glare.
Glare is a bad lighting phenomenon. When the brightness of the light source is very high or too different from the surrounding brightness, glare will occur. High brightness is the source of glare. Prolonged exposure to strong light can lead to blindness. Due to the stimulation of strong light on the eyes, especially the lens, the damage of the vitreous will cause photoelectric reaction to a certain extent, make the vitreous turbid and degenerate, and the visual acuity decreases significantly.
Glare will cause discomfort to the eyes, leading to visual fatigue. Being in the glare environment for a long time will also cause myopia and damage the eyes. In particular, teenagers are in the high-frequency period of eye use, and the eye structure is more fragile than adults. If they are harmed by glare for a long time, their eyesight is easy to be damaged, and even suffer from eye diseases. Students spend a long time in school and often stay in the dazzling classroom lighting, which will not only affect the quality of students' class, but also seriously affect the health of students' eyesight.
