![]() It’s the reason why you’ll see water droplets clinging to the branches of plants. Adhesion causes water to stick to surfaces like glass. If you’re wondering why the little water droplets attach themselves to the surface of the lens in the first place, it’s because of two specific properties of water: adhesion and cohesion. It's important that your mask fits well, but there are some extra ways to ditch the fog. You could strap it down with adhesive bandages or athletic tapes (but those aren't fun to rip off. You could add a flexible metal strip to seal the mask to your cheeks and nose. ![]() The fogging continues until the surface temperature of your glasses matches the surface temperature of the air (or warm breath) that surrounds them. Likewise, when you leave the cool comfort of your home and step out into the blazing heat of summer, your glasses also fog. Thus, when your hot breath escapes your PPE face covering and hits the surface of your glasses’ cooler lenses, they fog. Warm, moist air that hits a cool surface causes fogging. Fog Formation Informationĭo your glasses fog when you wear other PPE like a face mask, when you walk outside from indoors, or vice-versa? The reason is because of the temperature difference and the level of moisture in the air. ![]() Let’s nerd out and talk about why your glasses fog in the first place and how this magical lens coating prevents it from happening. All Stoggles safety glasses come standard with this semi-permanent, anti-fog coating. Whether you experience fogging on your sunglasses, eyeglasses, or safety glasses, it becomes an irritating event that can also place your eyes at risk of injury.Īnti-fog solutions are plentiful, but the true Cadillac of anti-fog fixes is an anti-fog coating applied during the eyewear manufacturing process. “I’ve had actually quite a few patients come in who’ve requested contacts to try to just wait it out,” Williams said.None of us are strangers to our glasses fogging and creating an impossible haze through which it’s nearly impossible to see. 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. ![]()
