How to Select Laser Safety Eyewear
, by Chas Waters, 3 min reading time
If you operate in the fields of scientific research, health and medicine, or manufacturing, you understand that safety glasses cater to unique applications. There is no such thing as a one-size-fits-all mentality, as the power of lasers changes based on industry and level of exposure. Finding appropriate safety eyewear may seem complicated at first, but Panther Vision is here to set you in the right direction.
The wavelength of a laser will influence safety eyewear requirements. The naked eye is extremely sensitive, and wearing safety glasses with light filters is the most proactive way to prevent unwanted irritation and even blindness.
Start With Your Laser
Laser technology is constantly expanding with new advancements. Before you can begin your search for safety glasses, you’re going to need to collect information about the laser you will be working with. Locate the owner’s manual of your device and identify the following:
- Operating wavelength
- Power outputs
- Beam diameter
- Beam delivery system
- Working environment
The level of protection you need corresponds to how a laser functions and the angle at which you view it. Your workplace may have preventative measures in place such as screens or films to diffuse exposure. However, it’s best to purchase safety glasses that exceed minimum recommendations in case of an accident.
How to Choose Laser Safety Glasses: Wavelength
Determining the power of your laser is a pivotal step in the safety equipment selection process. Additionally, getting a read on wavelengths and how they interact with your environment will help you find safety glasses with the correct optical density. Pay close attention to the nanometer and micrometer data on labels and plates to see which sections of the light spectrum you need your glasses to absorb.
Choosing laser safety eyewear with an optical density too low for your application can result in vision loss and injury. These measurements should always be calculated and reviewed by a professional.
Lens Type and Durability
Laser safety glasses are created using polycarbonate materials for durability, scratch-resistance and high-level impacts. There are situations that necessitate glass lenses, as well, as select high-power outputs require increased lens thickness for light filtration. If you are unsure which material is appropriate for your application, consult the owner’s manual of your laser or contact a Certified Laser Safety Officer for direction.
Guidelines set by the American National Standards Institute (ANSI) will help you find laser safety glasses. Inspect packaging and frames for article Z87.1 eye and face protection labels:
- Letter U is for ultra-violet filtering.
- Letter R products are engineered for infra-red filters.
- Letter L indicates visible light filtering.
- “Z87-2” products are prescription-based.
Comfort and Fit
The fit of laser safety glasses is just as important as the lens materials. Ensure your equipment covers both eyes, accounts for your peripheral vision and wraps around the sides of your face. You’ll likely wear your glasses for hours on end, so keep in mind that polycarbonate builds are lighter than glass.
Take the time to find a lens and frame shape that stays on your face without the need to constantly readjust. Some options allow you to perform adjustments for flexibility.
