Optical density at the exact wavelength, and a marking that states it

The best laser safety glasses for 2026

Laser safety glasses filter the light of a particular laser, and they are specific: a pair made for one wavelength may offer nothing against another. The first specification is the wavelength range the lens covers, in nanometres, which has to include the laser's own — diode lasers around 450 nm, CO2 lasers around 10,600 nm and fibre lasers around 1,064 nm need different filters. At each wavelength the lens has an optical density, a logarithmic figure where each step blocks ten times more light, and the density required depends on the laser's power and the maker's guidance. A standard marking printed on the frame or lens, stating wavelength and protection level under a recognised standard, is what distinguishes a tested filter from tinted plastic; a listing without a marking is not evidence of protection. Fit over prescription glasses and side coverage matter because light arrives from reflections, not only straight ahead. Visible light transmission decides how well the work can still be seen. This site reports what the markings state and never calls a pair safe for a given laser — the laser maker's instructions and the marking decide. We compare wavelength range, optical density, marking, fit, side protection and visible light transmission.
