Eye lamp really can prevent myopia?

Eye protection refers to reading and writing lamps that claim to have eye protection. At present, the eye-protection lights on the market are promoting "no radiation", "no flicker", "no shadow", "no glare" and other effects, and its most important selling point is "no flicker", that is to say this kind of lamp The light is stable and will not flash, protecting eyesight. But does eye protection really have the function of preventing myopia?

Although many of the eye-protection lights on the market are based on high-frequency flash and LED eco-friendly lamps, they do not have the ability to protect eyesight. Some of them also cause radiation to the human body and cause damage to eyesight.

Eye protection lamps and fluorescent lamps that are commonly used are fluorescent lamps. The basic working principle of eye protection lamps is to raise the low-frequency flash of ordinary lamps to high-frequency flash, that is, the eye protection lamp only changes the fluorescent lamp to 100 times per second. Tens of thousands of times per second, so the eyes do not feel the strobe light changes. High-frequency flash is not equivalent to no flash, but only to the speed that the human eye can't feel. From the theory of optometry, the higher the stroboscopic rate, the closer to a continuous light source and the closer it is to natural light. However, such speculations and ideas are still based on theoretical assumptions. So far no large sample population test has been seen. There is no direct relationship between eye protection and vision protection and myopia prevention. Although the high-frequency flash eye lamp is not easy to make the human eye have a sense of fatigue, but in the eyes under the light for a long time, the eyes will still be tired, with the eye protection, but also pay attention to the eye rest.

In addition, the light is too bright or too dark to damage the eyes, can cause visual fatigue, which will deepen the myopia, while the strobe light will have adverse effects on the eyes. Some eye protection lights are too bright, but they are not good for the eyes. Experts recommend that consumers choose to use traditional incandescent bulbs. The incandescent lamp is yellow light, softer, and because there is no interference from alternating current, the light is relatively stable.
