When using industrial laser equipment, it is crucial to correctly wear laser goggles and helmets in order to protect the eyes from potential damage caused by strong laser radiation. This includes avoiding prolonged exposure to the radiation, which can lead to serious harm to the cornea and retina and potentially result in vision loss or blindness.
Industrial laser produces visible and invisible radiations ranging from 100nm to 1400nm. UV beams(100-400nm) can lead to corneal damage while infrared light(400-1400nm) can penetrate the lens and harm the retina, resulting in permanent damage.
Although higher wavelength lasers are usually deemed safe, higher power lasers still pose a danger to the eyes.
Goggles are specifically designed to safeguard against certain wavelengths, working to decrease laser intensity or eliiminate the Maximum Permissible Exposure(MPE).
