The number one reason to use a green laser is daytime visibility.
Are green laser sights better than red.
You will have a much easier time seeing a green laser in broad daylight than red.
The human eye is better able to recognize colors in the green spectrum so a green laser is more visible under bright light conditions.
Not sure it makes that much difference in laser sights.
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.
Red light waves range from 620 to 750 nanometers and green light ranges from 495 to 570 nanometers.
Recently a green laser was introduced to the laser sight family.
Red is higher on the spectrum at 635 nanometers.
Green is close to the center of the visible light spectrum at about 532 nanometers.
