How to Know Your Laser Glasses Protect Your Eyes

Want to make sure that you’re wearing the right laser glasses?

“Are My Laser Glasses Protecting My Eyes?”

Laser Safety GlassesLaser safety glasses must be specified for the right laser if they’re going to protect your eyes, and choosing the wrong pair can have disastrous results.

Checking whether your laser glasses protect your eyes is as simple as checking whether the wavelengths printed on the glasses match your laser, and whether the Optical Density, or OD, rating on the laser glasses is high enough.

In general, you’re going to want an OD higher than 5 at the wavelength your laser operates at, though some situations call for higher or lower OD ratings.

Here are some things to keep in mind if you’re wondering how to know your laser glasses protect your eyes:

  • Laser glasses are marked to protect at specific wavelengths. Check the wavelength ranges on the glasses to see if they match the wavelength(s) your laser operates at.
  • Along with the wavelengths, Optical Densities (OD) are marked on the glasses for each wavelength range. Higher optical densities mean higher protection.
  • Optical densities above 5 are generally good enough for blocking powerful lasers.
  • Optical densities between 2 and 3 are generally used for laser alignment, where the laser is powered down and turned on so the beam can be aligned.
  • It’s always a good idea to check with your Laser Safety Officer (LSO) to make sure your laser glasses protect your eyes before using them yourself.

Laser glasses are vital to the safe operation of lasers, and they should be purchased with care to ensure that they provide the level of protection required to keep your eyes safe.

    I’m a pilot and I’ve had green and purple lasers shined at me while flying at night. The green laser blinded me for several seconds while I was approaching to land. I would like protection from future laser attacks but can’t afford to cut down on visible light transmission for the 99.99% of the time while night flying that lasers aren’t being shined at me. What would you recommend? Thanks.

    Hi I was wondering if you could tell me what would be the best protective laser glasses for me? Our surgical Laser machine uses 10600nm wavelength, and I want to make sure I get the best I can for our staff and they’re eyes.
    Thank You!

    What safety glasses would you recommend for using a 400nm 405nm 445nm 450nm Violet Blue Laser?

    Also, when wearing this eye protection, if I were to look at the laser cutting wood, would these glasses still protect my eyes?

    Thank you…

    Do you have any recommendations for eyewear that would be protective for me? I use a combination laser which contains both infrared/red laser diodes (635-660 nm and 808-830 nm) at a total power of 60 milliwatts – 130 milliwatts. Do you have safety goggles that would be protective of both these wavelengths?

    Wondering what may be best for me when it comes to laser safety glasses. We do not have a LSO at my machine shop. I work with a 3000 watt NTC Laser and a 2000 Watt Mitsubishi Laser. Any help would be greatly appreciated. Thank you

    I want to protect my eyes, but still be able to view a visble red laser (650 nm red) to align something. What are the correct glasses to purchase.
