The main principle of laser safety glasses is to filter and absorb laser energy through special materials and designs to 

                                      protect human eyes from laser damage.

                                      Laser is a kind of high-energy, high-brightness light. When it enters the human eye, it may cause permanent damage to 

                                      eye tissue and even cause blindness. Laser protective glasses generally use special filter materials to block the energy of 

                                      laser beams, including absorption, scattering, reflection and refraction of laser energy.

                                      Commonly used materials for laser protective glasses include glass, plastic, and film. These materials contain special 

                                      compounds or additives that absorb laser energy in specific wavelength ranges. When the laser is incident on the laser 

                                      protective glasses, the material will absorb the energy of the laser and convert it into heat energy, thereby protecting

                                      the human eye from the damage of the laser.
