Are green laser sights better than red.
Not sure it makes that much difference in laser sights.
Red light waves range from 620 to 750 nanometers and green light ranges from 495 to 570 nanometers.
Green can be used inside or out but green is much more visible outside and can be used to engage targets in similar circumstances.
The number one reason to use a green laser is daytime visibility.
Green is close to the center of the visible light spectrum at about 532 nanometers.
From the target s point of view having a red laser dot on your chest is very impactful.
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.
You will have a much easier time seeing a green laser in broad daylight than red.
Red is higher on the spectrum at 635 nanometers.
