Laser Protective Eyewear

Laser protective eyewear (LPE) is the most effective PPE for use around lasers and can include items such as goggles, face shields, or prescription eyewear with special filters or reflective coatings.

Personnel must use eye protection specifically designed by the manufacturer or selected by the LSO for protection against radiation when working within the NHZ of Class 3B or Class 4 lasers.

Consider the following points when selecting protective eyewear:

• Laser wavelength or range
• Optical density (OD) for that wavelength or range
• Damage threshold of the eyewear
• Visual transmittance of the eyewear
• Field of view and curvature of the lens
• Size of the eyewear
• Ventilation to prevent fogging and general discomfort
• Effect on color vision
• Impact resistance
• Flammability

In addition, LPE must include details, as follows:

• OD at appropriate wavelengths
• Manufacturer's recommendations on shelf life, storage conditions, and appropriate cleaning methods

Note that LPE must be specifically selected to withstand either direct or diffusely scattered beams.
