Laser safety glasses are a vital piece of personal safety equipment when working with lasers. Full protective glasses filter laser light completely, whereas protective glasses for alignment tasks attenuate the emitted laser light to a level that is safe for the human eye, while the laser still remains visible. It is crucial that the laser and the appropriate protective eyewear match.
Full safety eyewear protects the eyes against beams in the ultraviolet, visible, and infrared spectral ranges.
These goggles are used for applications where the eyes need protection, yet at the same time the laser beam still needs to be seen.
