1. When the harmful blue light reaches a certain energy (at the same time, the energy of blue light will be stronger than other lights), it can penetrate the lens and reach the retina, causing the retinal pigment epithelial cells to shrink or even die.


2. Due to the short wavelength of blue light, the focal point does not fall on the center of the retina, but a little more in front of the retina. If you want to see clearly, the eyeballs will be in a state of tension for a long time, causing visual fatigue.


And under normal circumstances, photoreceptor cells will bleach themselves after receiving photons and stop accepting photons, and continue to receive photons until a "visual cycle" is reached, while blue light photoreceptor cells do not have this cycle but continue to absorb blue light, thereby greatly increasing possibility of injury.


However, not all blue light is harmful. Some blue light plays a vital role in the regulation of melatonin, but prolonged exposure to blue light in the 440nm range may cause damage to the eyes. Therefore, what we have to protect against is actually prolonged exposure to the sun - in natural light, blue light is harmless.

If we stare at the screen for a long time, our eyes will receive more short-wave blue light with higher energy, so we need to pay special attention to it. is the blue light damage in this area.
