fog protection mixed together, diluting both). This uneven, thinner coating is the result of a technique where identical coatings are applied on both sides of the lens, which sacrifices the quality of one protective property over the other (scratch resistance vs. This precise, specialized dual-coating process is a first for North American safety eyewear.īy contrast, most competitive safety eyewear is dip-coated. HexArmor’s flow-coating application technology provides an anti-fog coating that is consistent, clear, uniquely bonded to the lens, and up to four times thicker than dip-coated alternatives.Įxclusive to HexArmor®, this flow-coating process also allows different TruShield® coating configurations to be applied to either side of the lens, giving the wearer more specific, quality protection where they need it most. Unrivaled protection with a face mask - and beyond Hydrophobic coatings are also detergent-based and start washing off after the first cleaning. Once several moisture droplets start to congregate, fogging occurs. This is a drastic change from the fog resistance that you’re used to as most competitive anti-fog coatings are hydrophobic, which causes moisture to spread out as it hits the lens instead of dissipating. Truly permanent anti-fog technologyĬhemically engineered to not wash off, HexArmor’s proprietary anti-fog coatings are fundamentally different from competitors – that’s because all HexArmor® anti-fog coatings are hydrophilic, which causes fog moisture to hit the lens and absorb into the coating eliminating fog quickly and efficiently (see visual below). HexArmor’s industry-leading TruShield® lineup of anti-fog coatings has two specific varieties to help keep your vision clear in these specific situations, TruShield®S and TruShield®2SF. To ensure your safety eyewear remains fog-free, superior anti-fog technology is key. Sound familiar? What you may not know – or know too well – is not only the frustration fogging causes but the productivity and compliance issues that come along with it. “I’ve had actually quite a few patients come in who’ve requested contacts to try to just wait it out,” Williams said.Wearing safety eyewear while also using a face shield, face mask, and/or respirator can cause the lenses to fog up due to low air circulation or diverted airflow, leading to severe or continuous fogging issues. Some plan to return to wearing glasses once face masks are no longer necessary. Andrew Williams of Vea Eye Health Professionals in Atlanta said that since the start of the pandemic he has fitted a number of patients, who are fed up with foggy glasses and poorly performing anti-fog agents, for contact lenses. Know, though, that while this formula was our testers’ favorite overall, individual results were mixed (and reflective of the many one- or five-star customer reviews for anti-fog sprays and drops). If you’ve bought a well-fitting, wired face mask but still experience fogging, and if taping your mask to your face seems impractical, you may find the Defog It drops worth a try. Surgical tape, also known as paper tape, or adhesive bandages can work well for this purpose. Surgeons have long taped the tops of their masks to their faces to seal them off completely, preventing fogging. Masks with adjustable nose-bridge wires are useful for this purpose, though even masks with the sturdiest wires can still let air escape at the top of the mask, which can fog up your lenses. The most effective way to reduce fogging on glasses or goggles while you’re wearing a face mask is to improve the seal between the top of the mask and your skin. However, they require frequent reapplication and can leave vision-blurring streaks-and as we found in our testing, your spit might work just as well. We tested three anti-fog drops, two anti-fog sprays, and one reusable anti-fog wipe in various environments, and we found Ultra Clarity’s Defog It drops to be the most compatible with different lens types and coatings. Trouble is, not all of them work that well, or for very long. Long used for occupational safety and recreational sports, anti-fog agents such as balms, drops, sprays, and wipes are meant to repel or evenly distribute fog, the fine droplets of water that accumulate on hard surfaces, so you can better see through your lenses. Foggy glasses-caused by a mismatch between the temperature of your breath and the surrounding environment-can range from a mild annoyance to a vision-clouding hazard, and the problem is all the more common now with the daily wearing of face masks.
