Choosing the right safety lens coating

Choosing the right safety lens coating

Fogging is the #1 hazard when it comes to safety eyewear. This is largely due in part to the way that safety glasses fit - close to your face. The low profile is necessary to keep out dust, debris, and other hazards from getting into your eyes, but oftentimes this close fit can trap moisture inside, causing fogging issues.

A lot of 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. Because their anti-fog coatings are detergent-based, after just a few washes, the coatings completely wash off.

Coatings that raise the bar

HexArmor® delivers a different coating solution, one that raises the bar in safety eyewear: permanent anti-fog performance that doesn't wash off and lasts the lifetime of the glasses.

Meet our four completely unique coatings that outperform even our highest-performing competitors: TruShield®, TruShield®S, TruShield®2F, and TruShield®2SF.

All HexArmor® coatings have these four unique characteristics:

1. Permanent coatings that are four times thicker than the competition and will not wash off
2. Hydrophilic anti-fog properties, meaning moisture is absorbed, not spread around (most competitors are hydrophobic and work like Rain-X® -- the moisture beads up and spreads on the lens)
3. Scratch-resistant properties
4. Flow-coated to allow for specific protection on either side of the lens (most competitors are dip-coated meaning you can’t get specific protection on either side of the lens)

Choosing the right coating

Each coating delivers a specific range of protection, so how you choose the coating you need depends on the environment you’re in and the activity you’re engaging in. Whether you’re tending to your lawn on a hot summer day or working through a DIY project in the garage, we have a coating for you.

TruShield®
Best for: Fogging from body heat and potentially dirty environments

Our signature coating, TruShield®, is a multipurpose dual coating that’s suitable for most environments, both indoor and outdoor. TruShield® lenses have permanent anti-fog on the interior of the lens that will not wash off and a scratch-resistant hard coat on the exterior of the lens.

Interior lens: Anti-fog

The following three coatings are for very specific activities and environments that call for different formulations of protection.

TruShield®2F
Best for: Hot to cold temperature transitions

TruShield®2F dual-coated lenses are ideal for moderately dirty environments where you could be transitioning from cold to hot or hot to cold. If you are constantly moving from an air-conditioned house to the summer heat outside, this coating will work well for you. TruShield®2F lenses have a combination of permanent anti-fog and scratch resistance on both the interior and exterior of the lens that will not wash off over time.

Exterior lens: Anti-fog and scratch resistance
Interior lens: Anti-fog and scratch resistance

TruShield®S:
Best for: Extreme outdoor environments

TruShield®S dual-coated lenses are ideal for environments where there’s a high degree of dirt or debris and more severe fogging factors. This coating would be perfect for activities such as chopping wood, clearing brush/fields, and even farming. TruShield®S lenses have dual-action permanent anti-fog on the interior of the lens and a scratch-resistant hard coat on the exterior of the lens.

TruShieldS anti-fog lens coating

Exterior lens: Scratch resistance
Interior lens: Dual action anti-fog

TruShield®2SF

Best for: Direct fog or steam environments

TruShield®2SF is our dual-action anti-fog coating, ideal for applications where there is constant environmental fogging, like if you’re working around a paper machine or around constantly steaming hot water. TruShield®2SF lenses have dual-action permanent anti-fog on the interior and exterior of the lens.
