Choosing Laser Safety Glasses

There are many different specifications and variations when it comes to choosing the best laser safety eyewear for your requirements.

The main specifications when choosing eyewear to consider are:

1) the Optical Density (OD) at your particular laser wavelength which is specified in nm (nanometers).  Optical density is basically the number of zeros that your laser wavelength is attenuated by.  For example an OD of 7 at 1064nm means that it attenuates that wavelength by 10,000,000X.

2) the L ratings which determines how well the glasses withstand a direct hit from the laser.  For more detailed information on this please refer to the full guide.

3) visible light transmission (VLT) which relates to how easy it is to see through the glasses. Typically under 20% means that they are best used in very well light environments

The next thing to consider is that they meet the relevant laser safety standards for your country. Australia has the same laser safety standards as Europe however different to the US. China typically manufactures laser glasses for the US market which tend not to have the relevant L ratings marked on the lenses that are required in Australia.

The standards that Laser safety eyewear should comply with include: AS/NZS IEC 60825.14:2014 (AU & NZ), AS/NZS 1336:2014 (AU & NZ), FDA (US) and EN207/208 (European)

The style of eyewear also needs to be decided. Typically the universal fit over style is the most popular as it covers all wearers however modern wrap around style may suit others better.
