Laser Protective Goggles are highly effective in preventing accidental eye injuries caused by the laser of the H2D Laser module. For lasers with wavelengths ranging from 200 to 450 nm (the H2D Laser emits a 450 nm blue laser), the protection level reaches OD5+, meaning that the laser power transmitted through the lenses is reduced to one hundred-thousandth of the original power. For lasers with wavelengths ranging from 900 to 1100 nm (primarily infrared light), the protection level reaches OD6+, indicating that the laser power transmitted through the lenses is reduced to one millionth of the original power, significantly reducing glare after filtration.
