The human eye is better able to recognize colors in the green spectrum so a green laser is more visible under bright light conditions.
Are green laser sights better than red.
Different wavelengths in the visible spectrum produce different colors.
The eye s frequency response is bell curve shaped with the highest point of the curve being in the green while the red lies on the right end of the bell curve.

Green is close to the center of the visible light spectrum at about 532 nanometers.
The number one reason to use a green laser is daytime visibility.
Red light waves range from 620 to 750 nanometers and green light ranges from 495 to 570 nanometers.
You will have a much easier time seeing a green laser in broad daylight than red.
Recently a green laser was introduced to the laser sight family.
Not sure it makes that much difference in laser sights.
