"Washing the spectacles with soapy water leaves behind a thin surfactant film that reduces this surface tension and causes the water molecules to spread out evenly into a transparent layer,” the article reveals.
The Annals of the Royal College of Surgeons of England published an article in 2011 that offered a simple method to prevent fogging, suggesting that, just before wearing a face mask, people wash their spectacles with soapy water, shake off the excess and then allow the lenses to air-dry. Tie the mask crisscross so that the top ties come below your ears and the bottom ties go above. If you are using a surgical mask with ties, a 2014 article in the Annals of the Royal College of Surgeons of England advises going against your instincts. Also, make sure the top of your mask is tight and the bottom looser, to help direct your exhaled breath away from your eyes. The tissue will absorb the warm, moist air, preventing it from reaching your glasses. But there are other options, including antifog lens coatings, sprays and wipes.Īn easy hack is to place a folded tissue between your mouth and the mask. The easiest, and least expensive, way to ensure that your glasses don't fog is to wear a snug-fitting mask with a tight seal across the top that prevents your breath from escaping, says Moran Roni Levin, M.D., assistant professor of ophthalmology at the University of Maryland School of Medicine. The effect is similar to how a hot shower's steam fogs up a cool bathroom mirror. When it's cold, your breath puffing up through the top of the mask clouds the lenses, especially when you go from the chilly outside to the warmer indoors, or in summer from heat outdoors to cool air-conditioned indoors, and the mask isn't tight around your face. That means face masks are back in many parts of the country to decrease the spread of COVID-19 and fogged-up glasses are making a return with them.

VS Eyewear’s Permanent Anti Fog coating for prescription safety glasses demonstrate superior fog free properties under a variety of conditions where fogging is an issue. The lenses may develop a layer of water instead of fog, but the water is transparent and is not dangerous. The result is a coating that NEVER fogs, even when going from the coldest conditions to a hot, humid climate. The coating works on a molecular level to keep water molecules from bunching together and causing the blinding fog that is so dangerous on safety glasses. Typical applications are safety goggles, prescription safety glasses, motorcycle goggles, and industrial safety glasses. It includes a hard anti-scratch coating which can be used where ever surface fogging is an issue.
