For the sake of my eyes, I did a lot of homework and finally bought the Fire Eye Crystal L1 Table Lamp, which is a table lamp that protects children's eyesight, but since the light is not harmful to the eyes, I still chose it. I learned that at present, many friends are using white LED lights like me before, which has a very low color rendering and high blue radiation brightness. That is to say, the words that can be seen clearly at a glance under natural light will take a few more seconds to see clearly under the white LED light, and after a long time, the eyes will be very tired, and the loss of vision will be a matter of time.

And this fire eye crystal L1 table lamp solves these problems very well, it fundamentally removes the harm caused by the surplus of blue light in traditional LEDs, and its spectrum is very close to the natural spectrum. Doing homework indoors is very similar to doing it in natural light, and your eyes don't get tired.

I've been using the fire eye crystal L1 for a while, the experience is very good, much better than the previous table lamp, I also bought one for my brother some time ago, it is worth recommending.
