For a long time, everyone likes to buy items according to common sense of life, but in fact, in the purchase of LED eye protection table lamps, some common sense is precisely wrong, and these errors are one of the culprit of myopia.
There are three main points:
1, The brighter the light, the better
Many parents think that the brighter the light, the better the lighting effect, the less damage to vision, so they often buy high-density table lamps for their children. In fact, this is very wrong. Excessive light will enhance reflection, and strong reflection will force the eye to be in a contracted state, reducing the resolution, so that the prper line of sight cannot be maintained.
Many times, children read books and get close to books. The closer they are, the closer they are because the lights are too bright. The result of this long-term is the child's myopia. In addition, the light is too bright, and it is easy to produce harmful light such as spots and glare.
2, White light is better
Generally, the color temperature of white light is above 6000k, which is not in the intermediate color temperature (3300-5300K) range suitable for reading, but in the range of high color temperature (5300K or more), so that white light is not suitable for children to learn.
Moreover, the high color temperature light source is white and cool, and it is a cool color, and the reflection effect is strong. If the child learns under such light for a long time, the visual effect is reduced, the eye fatigue is accelerated more quickly, and the eye burden is increased.
3, Only look for no stroboscopic
The biggest reason many eye protection lamps claim to be able to protect the eyes is that there is no stroboscopic light. However, any light bulb must be strobed as long as it is energized, only visible and invisible to the naked eye. Therefore, the correct expression without strobe should be no video flash.
Secondly, although the table lamp without video flashing does have better light quality, strobe is not the only standard for eye protection. Therefore, parents should not only look for no strobe when selecting lamps, but should consider various aspects. Only in this way can we choose the best quality lamps.
Selection suggestions: When purchasing LED eye protection desk lamps, do not use the inherent wrong thinking to choose, nor blindly pursue no stroboscopic, color temperature, blue light, color rendering, etc. is also a point we need to pay attention to, as long as this can be truly selected A quality table lamp.
