What TruShield® anti-fog coating is right for your safety glasses?

Fogging is the #1 hazard when it comes to safety eyewear. This is mainly due to how anti-fog safety glasses fit – close to your head. The low profile is necessary to prevent dust, debris, and other hazards from entering your eyes, but often, this close fit can trap moisture inside, causing fogging issues.

Many safety eyewear brands have developed solutions for fogging that work well… until you clean them.

Where these brands fail is in the longevity of their anti-fog performance. This is because their anti-fog coatings are detergent-based and wash off after a handful of cleanings, making the anti-fog capabilities in the eyewear ineffective and unusable.

That's why choosing the right lens coating matters. HexArmor® TruShield® technology is available in four coating configurations – TruShield®, TruShield®S, TruShield®2F, and TruShield®2SF – designed to provide different combinations of permanent anti-fog and scratch-resistant protection to meet the demands of the job and different work environments.

So, which anti-fog safety glasses are right for your application? Let's break down our TruShield® coatings to help you choose.

What is TruShield® anti-fog technology?

In short, these are coatings that raise the bar. TruShield® is HexArmor’s family of four premium lens coatings designed to provide permanent anti-fog performance and scratch-resistant protection for safety eyewear. Unlike detergent-based anti-fog treatments that can gradually wash away through repeated cleaning, TruShield® coatings are permanently bonded to the polycarbonate lens – helping maintain anti-fog performance for the life of the eyewear.

TruShield® coatings use hydrophilic, or "water-loving," anti-fog technology, meaning they interact with and absorb moisture rather than simply repelling water across the lens surface like Hydrophobic, or "water-repelling," lens coatings. This helps prevent visible fog from building up when workers encounter humidity, temperature changes, perspiration, and other demanding workplace conditions. You can learn more about the difference between Hydrophilic coatings and Hydrophobic lens coatings here.

But anti-fog performance is only part of the equation. TruShield® coatings are also flow-coated, meaning anti-fog and scratch-resistant coatings are applied to specific sides of the lens based on the level of protection needed for different work environments.

Across the TruShield® coating family, you'll find:

• Permanent anti-fog performance: Hydrophilic technology is permanently bonded to the lens and engineered not to wash off through repeated cleaning.
• Scratch-resistant protection: Helps protect lenses against everyday wear that can interfere with clear vision.
• A thicker coating: TruShield® coatings are four times thicker than competitive coatings.*
• Purpose-built options: Different combinations of anti-fog and scratch-resistant protection are available to match different workplace conditions.

As mentioned before, there are four fundamentally different coatings available. Let’s compare and see which one best fits your work environment.

Which TruShield® coating should you choose?

With four coating options, choosing the right option comes down to the conditions your safety eyewear faces – from everyday wear and occasional fogging to frequent temperature changes, dirt, debris, and persistent moisture.

TruShield® is the most popular, everyday coating style – and TruShield®S, TruShield®2F, and TruShield®2SF are considered more specialty, with very unique properties that make a huge difference in certain tasks. The goal? Keeping vision clear and helping ensure workers are wearing their safety glasses – keeping them comfortable and in compliance.

TruShield®: Multipurpose anti-fog protection

HexArmor's signature coating and a versatile option for most applications and work environments. The interior of the lens features permanent hydrophilic anti-fog lens coating to help manage moisture, while the exterior features a scratch-resistant hard coat to help protect against everyday wear.

Best for: General-purpose applications where workers need reliable anti-fog performance paired with exterior scratch resistance.

TruShield® S: Added protection for dirt and severe fogging

TruShield®S is designed for environments with a higher degree of dirt or debris combined with more severe fogging factors. The interior features dual-action permanent anti-fog protection, while the exterior uses a scratch-resistant hard coat.

Best for: Dirtier work environments where eyewear is exposed to both fogging conditions and abrasive hazards.

TruShield® 2F: Protection through temperature changes

TruShield®2F is designed for workers who frequently transition between hot and cold environments. Permanent anti-fog protection and scratch resistant protection is applied to both the interior and exterior of the lens.

Best for: Applications involving frequent temperature changes and moderately dirty environments.

TruShield®2SF: Maximum anti-fog performance

TruShield®2SF is designed for applications where environmental fogging is a constant challenge. Dual-action permanent anti-fog protection is applied to both the interior and exterior of the lens to help maintain visibility through demanding fogging conditions.

Best for: Work environments with persistent or severe environmental fogging.

How are TruShield® coatings applied to safety glasses?

HexArmor® uses a flow-coating process that allows specific anti-fog and anti-scratch coatings to be applied to different sides of the lens based on the protection needed.

For example, TruShield® combines permanent anti-fog protection on the interior with a scratch-resistant hard coat on the exterior. For environments where fogging can affect both sides of the lens, options like TruShield®2F and TruShield®2SF provide anti-fog protection on both surfaces.

This targeted approach allows workers to choose a coating configuration based on the conditions their eyewear actually faces – rather than relying on the same coating setup for every application.

Why does choosing the right anti-fog coating matter?

The best safety eyewear can only protect workers when it stays where it belongs – on their face. When lenses repeatedly fog, workers may be more likely to wipe, adjust, or remove their eyewear to see clearly, leaving their eyes exposed when hazards are still present.

That’s why choosing an anti-fog coating isn’t just about preventing an inconvenience. The right coating should match the conditions workers actually face, whether that means everyday fogging, frequent temperature changes, dirt and debris, or persistent moisture.

For some applications, standard TruShield® may provide the right balance of permanent anti-fog and scratch-resistant protection. More demanding environments may benefit from TruShield®S, TruShield®2F, or TruShield®2SF. The goal is to choose protection that performs consistently in the environment so workers can keep their safety eyewear on and focus on the task at hand.

Ultimately, the right anti-fog coating is the one that helps workers see clearly and wear their safety eyewear consistently throughout the job.
