Laser safety glasses are specialised protective eyewear designed to reduce the intensity of laser radiation reaching the eye. Unlike standard safety glasses, laser eyewear contains filters engineered to block or attenuate specific wavelengths produced by laser systems.

Lasers are widely used in medical, industrial, scientific, and research environments. Because laser beams can concentrate a large amount of energy into a very small area, unprotected exposure may pose a risk to sensitive parts of the eye, particularly the retina.

Laser safety glasses work by using optical filters that absorb or reflect laser wavelengths before they reach the eye. Each pair is designed for a defined wavelength range and optical density (OD), which indicates how effectively the lens reduces laser energy.

It is important to ensure that protective eyewear matches the wavelength of the laser system being used. Lens markings typically display wavelength ranges and OD ratings so users can confirm compatibility.

In workplaces where lasers are present, properly rated eye protection is an important part of broader laser safety practices.
