Does many people feel that myopia in the family is caused by playing with mobile phones? In fact, parents only realize that there is a part of the reason for mobile phones, but if the lamp is not used properly, it will only speed up the speed of myopia in children. After all, children use lights much longer than the time they look at mobile phones.
When choosing a light, I think I must buy a light one. In fact, it is causing chronic damage to the child's eyes. How should I choose a good eye protection lamp? Be sure to pay attention to these three points.
1. You must choose blue light certification. High blue light will affect children's vision. is sorted from low to high by hazard risk. Retinal blue light hazard groups are RG0, RG1, RG2 and RG3.
Current safety standards stipulate that the blue light hazard group of LED lamp products cannot exceed RG1 or RG2. In order to better protect the young eyes of adolescents, it is stipulated that the retinal blue light hazard group of children's reading and writing desk lamps should not exceed RG0.
2. Choose a lamp without strobes. The strobe will make the child's pupils constantly expand and shrink, which will make it visually fatigued. LED lamps with such a huge difference in strobes look almost no different from the naked eye.
When choosing a lamp, just take out the mobile phone you carry with you, turn on the camera function, and point the lens at the lit light bulb, and you can tell the difference at a glance. With strobe-high light bulbs, frequently fluctuating lines will appear on the screen of the phone.
3. Choose a color rendering index greater than 90. The higher the display index, the closer it is to the sunlight, and the better it can restore the color of the object itself. A good lamp can even reach more than 95. But don’t just look at the number of RA values. RA is only the average value from R1 to R8. R9 is the most difficult color to restore the real color. It depends on the high values from R1 to R15.
Normally, ceiling light , which does not have eye protection function, has a high blue light peak, and the spectrum is not continuity, and the color rendering index is around 70. It is not an IQ tax to spend more money to buy a lamp. Think about it from another perspective, should you spend more money to buy a lamp, or to give your child a glasses?
