1. This is a graph of the relationship between wavelength and optical density (light absorption value). Obviously, the absorption value of different wavelengths is of course different. This glasses mainly protects the wavelength of 190-550nm;
2. Optical density is a complex characteristic of materials that can slow down the propagation speed of light and produce refraction (refraction) effects;
3. Different lasers (and corresponding wavelengths) have different impact on the human eye; Generally speaking, the greater the optical density, the better the protective effect.
