Protective eyewear with innovative anti-fog technology can help boost safety and productivity while reducing product maintenance costs. Take a look at one anti-fog solution from Uvex by PIP.
Employers are responsible for making sure that workers use appropriate eye protection for the hazards at their workplace. Although federal guidelines say that eyewear lenses can fog and may need to be cleansed regularly, it can be easy for employers to lose sight of how big of a problem fogging is.
Eyewear fogging can occur when an environment is hot and humid, when a worker moves from a cold area to a warm one or when physical exertion generates warmth in the facial area. Handling hot materials may also cause fogging, says Tina Perales, national product sales manager for hand, eye and face at PIP Global Safety, a global personal protective equipment (PPE) leader in worker safety.
“It doesn’t matter what environment you’re in,” Perales says. “Anytime that a glass becomes fogged, it’s going to impede your vision. You’re going to remove your glasses, and it’s going to create a risk of an accident. You’re going to be noncompliant. You could have a recordable injury, which in turn would lead to higher insurance rates and lost productivity.”
Sometimes changing the environmental conditions at the facility can reduce the chances that eyewear will fog—by adding a cooling system to avoid temperature differences, for example. But technologies in the eyewear itself are more reliable to keep people’s vision clear.
Eyewear manufacturers typically use one of two types of lens surfaces for getting rid of fogging:
Hydrophilic surfaces work by absorbing moisture on the lens and distributing it evenly, essentially clearing the vision.
Hydrophobic surfaces work by repelling moisture so it runs off and doesn’t cling to the lens.
Uvex by PIP’s patented innovation leverages both hydrophilic and hydrophobic anti-fog methods in its Uvex HydroShield® safety eyewear.
“We’re absorbing that moisture, and then the moisture is being pulled away from your vision and down to the outside of the lenses,” Perales says. “So, you will see moisture, but you’ll see it dripping from the outside of the lenses as it clears from your vision.”

HydroShield delivers at least 180 seconds of fog-free time, far surpassing the federal anti-fog standard of eight seconds.
The American National Standards Institute and the International Safety Equipment Association first included criteria for anti-fog PPE in their 2020 update of the eye and face protection standard (ANSI/ISEA Z87.1). Compliant products are marked with “Z87” along with “X” for anti-fog.
The power of HydroShield’s anti-fog properties is in the manufacturing.
“Our anti-fog technology is permanently bonded to the lens and lasts the lifetime of the lens, so there is no need to reapply,” Perales says.
Permanent bonding helps HydroShield withstand harsh conditions and repetitive cleaning, leading to long-term fog protection. Plus, because workers aren’t having to frequently stop what they’re doing to readjust their glasses or reapply a coating, they are more comfortable and productive during their shifts. Employers also avoid extra costs for anti-fog supplies, such as application wipes.
Testing shows that HydroShield’s fog-free protection lasts 90 times longer than most other anti-fog products, dependent on the environment and application.
Besides fogging, lens scratching is another challenge that employers must overcome. “Scratching is also a concern,” Perales says, “because once a glass becomes scratched, customers would tend to replace it.”
To address the issue, some eyewear manufacturers include anti-scratch coatings. With Uvex’s products, she says, “our anti-scratch coating is two times more effective.”
It’s one thing to provide protective eyewear, and it’s another to ensure that people are actually wearing it. Employers would do well to have a variety of options to suit worker preferences for comfort and style while also ensuring compliance.
Fortunately, HydroShield’s anti-fog properties are available in Uvex Avatar™ Plus, a comprehensive family of safety eyewear that includes three styles.

“We call it a one-stop shop, because we offer safety spectacles, goggles and an over-the-glasses option—that pretty much covers most of what you need within your facility,” Perales explains.
The safety spectacles add versatility and comfort with a floating nose pad and flexible temple design, plus a variety of lenses available in different tints and coatings.
“If you choose a family like this, you give your employees options,” Perales says. “This allows them to select what works best for them, and it also allows the safety manager to know that everyone is in compliance.”
Another smart way the Avatar Plus line supports compliance is plain to see: All products have a subtle but unmistakable frame color.
“Citrus green is easy to spot,” Perales says. “The Avatar Plus family lets the safety manager look out through the facility and make sure that everyone’s wearing a safety glass that complies with the ANSI standards. That’s most important.”
