The misunderstanding of LED eye protection table lamp selection should be known, and these mistakes are one of the culprits that cause myopia.
For a long time, everyone likes to buy items according to common sense in life, but in fact, in the purchase of LED eye protection table lamps, some common sense is just wrong, and these mistakes are one of the culprits that cause myopia.
There are three main points:
1. The brighter the light, the better
Many parents think that the brighter the lamp, the better the lighting effect, the less damage to the eyesight, so they often buy high-brightness desk lamps for their children. In fact, this is very wrong. Excessive light will strengthen the reflection, and the strong reflection will force the eyes to be in a state of contraction, reducing the ability to resolve, resulting in the inability to maintain an appropriate viewing distance.
Many times children read books and get close to the book. The closer they read, the closer the light is. The result is that children are short-sighted in the long run. In addition, if the light is too bright, it is easy to produce harmful light such as flare and glare.
2. White light is better
Generally, the color temperature of white light is above 6000k, which is not in the middle color temperature (3300-5300K) range suitable for reading, but in the high color temperature (above 5300K) range. It can be seen that white light is not suitable for children to study.
Moreover, the light source with high color temperature is white and cold in color, which is a cool color and has a strong reflection effect. If children study under this kind of light for a long time, the visual effect will be reduced, the eyestrain will be accelerated faster, and the eye burden will be increased.
3. Only look for no stroboscopic
Many eye protection lamps claim that the biggest reason for eye protection is that there is no stroboscopic. But any light bulb will flicker as long as it is powered on, only visible and invisible to the naked eye. Therefore, the correct expression for no flicker should be no video flicker.
Secondly, although desk lamps without video flicker do have better light quality, stroboscopic flicker is not the only criterion for choosing a good eye protection lamp. Therefore, when choosing a desk lamp, parents should not only look for no stroboscopic, but should consider many aspects. Only in this way can they choose the best quality desk lamp.
Selection suggestion: When purchasing LED eye protection desk lamps, do not choose with inherent wrong ideas, nor blindly pursue no stroboscopic. Color temperature, blue light, color rendering, etc. are also points we need to pay attention to. Only in this way can we really choose A quality desk lamp.
