Blue light can reach the retina through the refractive medium of the eye, and over time it will cause the aging and functional degradation of the retina. But in fact, the eyes have many protection mechanisms in the process of evolution, such as squinting, pupil contraction, lutein contained in the macula of the retina, the anti-oxidant repair mechanism of the retina, etc., which can protect our eyes from the damage of blue light. Also, after scientific testing, the blue light emitted by electronic products is a few percent of the intensity of blue light in natural light, which means that as long as the electronic products are not used continuously every day (for example, more than 8 hours a day), blue light will not be causes obvious damage to the eyes.
