The classification of "laser" depends on the wavelength, because different wavelengths cause different damage to human tissues and organs. Therefore, after different types of lasers are classified according to their working ability, they are classified according to the following four levels, and cause harm to human body. The first three times are harmless zero gravity lasers. Using these kinds of laser light is harmless to the human body or without using the eyes directly will not cause damage to the eyes. This kind of laser does not need to manipulate the second grade laser... Although the laser performance is very low, it will not cause damage to the eyes if you scan the eyes occasionally, but as long as you don't directly look at the Laser pointer for a long time. Affected by photons, it may also damage the retina, but this laser has no thermal damage to human skin. Medium power laser will directly damage the eyes when the force focuses on the laser. Diffuse laser is usually not dangerous or that kind of... Dad's laser. This laser light not only directly damages the eyes and skin, but also causes serious damage. Extensive reflected light can also damage people's eyes.
