When choosing the most appropriate laser goggles for use in the US its important to make sure they are certified to the relevant laser safety standards.

Laser goggles in the US need to be marked with L ratings , wavelengths (nm), optical densities (OD) and visible light transmission (VLT).

The L ratings determine how long the glasses can withstand a direct hit from the laser, the optical densities determine the attenuatio of the laser at a given wavelength for example an OD 3 at 650nm will cut down laser light at 650nm by 1000 times.
