This document applies to eye and face protectors intended to provide protection against accidental exposure to laser radiation within the wavelength range 180 nm to 1 mm. It defines the requirements, test methods and marking. Laser protective filters used for intentional exposure to laser radiation, as viewing windows in laser equipment or incorporated into optical instruments such as operating microscopes which may be used for deliberate viewing of laser radiation as part of their function, and loupes, are outside the scope of this document. This document is applicable to devices intended for patient protection during medical laser procedures except for treatment in the periorbital area. The eye protection described in this document is intended for use at normal ambient temperature (23 ± 5)°C, unless specified in particular requirement(s).
