Obviously, the absorption value of different wavelengths is of course different. This glasses mainly protects the wavelength of 190-550nm & 800-1100nm.Optical density is a complex characteristic of materials that can slow down the propagation speed of light and produce refraction (refraction) effects.Different lasers (and corresponding wavelengths) have different impact on the human eye ；Generally speaking, the greater the optical density, the better the protective effect. Biological Impacts in Relation Laser Safety Why do you need laser protective glasses (necessity!) Laser protective glasses, the purpose is to prevent laser.There are usually two kinds of lasers, the lasers between 400nm-780nm is visible light, the light can be seen. Lasers above 780nm are infrared light and are usually invisible.High-energy laser, the most common is optical 1064nm(fiber ); 10600nm(co2 laser), invisible to human eyes. For example, suppose that the light hits the human eye, and the human eye does not respond at all, and does not know timely prevent it by closing the eyes. If the laser energy is slightly stronger at this time, it may cause blindness. (The phenomenon is: I suddenly went blind without noticing it) Mention: If you value your eyes, these things are the real deal. When conducting high-energy laser experiments and research, not only must wear protective glasses, but also no reflective objects on the whole body. Such as watches.Laser protective glasses are mainly used to prevent laser spots and stray light. Even if you wear laser protective glasses, people cannot look directly at the laser.Please do not look directly at the laser, otherwise it will cause irreversible and permanent eye damage.
