Contractors tasked with protecting workers from the COVID-19 virus have greater awareness for engineered controls that enable increased personal hygiene. One engineered control should focus on how to help workers reduce contact with their face and eyes. The CDC says workers can become infected from touching their eyes with contaminated fingers.

For many industries, reducing this eye and face exposure is relatively easy. But for contractors who require the use of personal protection equipment including safety glasses, goggles, and face shields, in tough conditions, there is a major problem – fogging on eyeglasses.

An Anti-Fog (AF) System Can Help Reduce Virus Spread

For years, safety directors have approached fogging as a worker’s obstacle to wearing safety glasses. A quick wipe of moisture from the lens surface could be safely accomplished when there was no risk of contact from fluids or solid particles.

But with the potential of virus spread, reducing the frequency of self-contact of PPE near a worker’s eyes is now a health priority. And this becomes even more difficult now that OSHA has recommended contractors include an administrative control requiring workers to wear face coverings on projects, increasing the potential for fogging eyewear.

Contractors can help workers experience less eyeglass fogging by providing proper eye related PPE, body cooling products, form fitting face masks, and anti-fog (AF) lens treatments.

Why Fogging Occurs

Construction workers experience fogging of safety eye protection for three main reasons.


Construction occurs in uncontrolled environments that can be subject to high humidity. The more moisture in the air, as on hot and humid days, the more likely lenses and shields will fog.


Face covering styles come in many styles and fabrics. While all aid in reducing virus spread, some allow warm, moist breath to move upward enveloping eye protection surfaces.

Heat And Sweat

The more common reason for fogging is the trapping of air between the interior surface of the lens or shield and the wearer’s hot face. When working hard, the body heats up, produces sweat, contributing to lens fogging.

4 Ways To Prevent Fogging

1. Select safety glasses, goggles and face shields that are designed to reduce fogging.

When choosing eyeglass frames, select style and fit that allows for more air circulation by not sitting too close to your face but still protecting your eye from danger. Some safety goggles are designed with vents to allow airflow, but be sure to check if they can be used for each task. And face shields should extend down below the workers chin to help direct flow.

2. Cool your face and head.

There are several accessories that reduce moisture and help cools a worker’s face area. Hardhat headband made from absorbent products soak up any sweat. There are a wide range of cooling products that wick away moisture from a workers, neck and head area. https://www.whitecap.com/ergodyne-chillits-blue-high-performance-dew-rag-64327#12481-34312481/

3. Use form-fitted face coverings.

When properly worn, these coverings create a barrier on your face covering between your mouth and nose from the safety glasses. Form fitting masks are designed to be positioned high on noses and securely tightened for a snug closing the gap around the bridge of the nose. They often have a metal clip that helps close the gap around the nose. If they don’t, try to position the safety glass frame on the mask to create a seal.

4. Use An Effective Anti-Fog System

While the first 3 suggestions can help reduce the fogging, the most effective path for clear vision is to use products that employ Anti-Fog (AF) protection on all surfaces.  AF formulations now include chemical technologies that go beyond just coating the surface with a soapy film.

For example, H2MAX, created by Pyramex, applies a durable, anti-fog treatment for that remains on lens surfaces even after repeated cleanings, a huge plus for construction workers. The anti-fog treatment extends the life of a safety eyeglass. The coating resists surface abrasion from both jobsite hazards or normal wear and tear.

Anti-fog treatments add to jobsite safety by provide workers maximum clarity in the most extreme temperature and humid conditions. H2MAX meets the appropriate ANSI and Canadian product safety standards.
