Selecting Laser Safety Eyewear

Lasers are useful tools in numerous fields, such as medicine, research, industrial, etc. The downside to using lasers is safety concerns. Especially eye hazards.  

Ordinary sunglasses do not protect your eyes against lasers. Only eyewear made for protecting against lasers, such as laser safety glasses, should be used when lasers are in use. Laser safety eyewear made for specific wavelength bands and Optical Density (OD) for the lase used is required equipment. 

Optical Density (OD)

OD is a measurement of how much light is absorbed by the material of the lens. 

Laser Classes

Lasers are classified by their: 

  • Energy
  • Wavelength
  • Duration of exposure
  • The cross-section area of the beam 

The weakest to strongest classes are 1, 1 product, 1M, 2, 2M, 3R, and 4. It is crucial to know the class and the wavelength of the laser radiation to ensure proper eyewear use. 

Types of Laser Lenses Material

The two types of lens material in laser glasses are glass and plastic. Glass lenses absorb the laser energy using rare elements. Plastic lenses block certain wavelengths by using specific inorganic dyes.
