This European Standard applies to eye-protectors used for protection against accidental exposure to laser radiation as defined in EN 60825ā€‘1:2007 in the spectral range 180 nm (0,18 Āµm) to 1 000 Āµm. It defines the requirements, test methods and marking.

A guide is given in the informative Annex B for the selection and use of laser eye-protectors and filters in appliances.

This European Standard does not apply to protectors for intentional exposure to laser radiation.

EN 208 applies for laser adjustment eye-protectors.

Before selecting eye protection according to this European Standard, a risk assessment should first be undertaken (see Annex B).
