Why are people more sensitive to green lasers?
Lasers with shorter wavelengths lose more in the atmosphere, so the green Laser pointer is easier to see than the red laser beam. The green laser is more easily absorbed by dust in the air, and the green laser pointer is more easily reflected, so the beam of the green laser pointer is more visible than the red laser pointer. Human evolution is often caused by environmental changes. Similarly, the human eye is currently the most sensitive to green, and it is also inseparable from environmental factors. Our color vision system will produce a compensatory response to changes in the external environment, so that your color vision system can keep up with the changes in the environment.

At the same time, you should also be able to see that the number of cone cells that perceive blue laser light is the least, and our eyes are extremely insensitive to blue light. This may cause the blue light produced by the electronic screen to cause damage to our eyes when we are playing with electronic products, and we cannot detect it because of our insensitivity to it. If you play with your mobile phone for a longer time, your eyes will become tired and sore, and you will become a little fuzzy when you look at things. Everyone must feel the same. The actual damage to the eyes of the mobile phone will definitely be much more serious than we feel. Friends who love to play with mobile phones and computers, really need to beware of blue light on electronic screens.
