Laser safety eyewear markings provide critical information about the protection offered by the filter.

These markings help identify:

Proper laser safety eyewear should always include clear and legible markings so users can verify the correct protection is being used for the laser system and application.

All laser safety glasses and goggles include markings identifying the wavelength range and corresponding Optical Density (OD) specifications of the filter.

For example:

These markings identify the wavelengths where the filter provides the specified level of attenuation.

Laser safety protection is wavelength-specific, which is why these markings are an important part of proper laser safety selection and verification.

For additional information on Optical Density and wavelength notation, see our Optical Density (OD) guide.

Our CE marked laser safety eyewear includes its own unique marking style incorporating the required European certification markings and manufacturer information.

For additional information regarding CE markings and European laser safety standards, see our article: How to Read CE Markings.

Laser safety eyewear markings are positioned so they do not obstruct the user’s field of vision during normal operation.

Proper marking placement helps ensure:

Laser safety markings help users verify that the eyewear matches the wavelength and protection requirements of the laser system being used.

Laser safety protection is wavelength-specific, and markings provide a quick method for confirming the correct filter has been selected.

No.

Different standards and certification systems may use different marking conventions.

For example:

Laser safety markings should remain legible throughout normal product use.

If markings become damaged or unreadable, the eyewear should be evaluated before continued use to ensure the correct protection can still be verified.
