How to prevent cheap laser pointer changes

Cheap and powerful green lasers emit more infrared light than green light. This is very dangerous because infrared rays are invisible to the human eye. Under a small amount of visible light, the eyes are programmed to shrink naturally and look away, or to close for self-defense. If you can't see the light, or infrared, this natural reflection is useless. In order to reduce infrared radiation, we always insist on using infrared filters. The infrared filter can filter the infrared light while adjusting the green light. As mentioned earlier, we do not provide low-quality and cheap green laser pointers. Today, all the green lasers we provide are the highest quality laser pointers that do not emit infrared light.
