Why is the human eye sensitive to the green laser pointer beam?

In a dark workshop, it is easy to see your laser used for measurement, regardless of whether the laser is red or green. However, once the lights are turned on, green laser pointers have a significant advantage over red lasers because they are brighter to the human eye. The reason is that the green wavelength is closer to the center of visible light than the red wavelength. On average, under the same output power, the brightness of the green laser is about four times that of the red laser. Literally translated, "sensitivity" is indeed sensitivity, but it depends on the context. This sensitivity means that compared with other wavelengths of light, yellow-green light gives people the perception of higher brightness. It does not mean that human eyes are good at capturing green laser beams. Dynamic.
