Alternatively, you could purchase covers with adjustable straps for extra convenience.Īnother helpful tip is to buy the best anti-fog sprays or cleanse wipes designed explicitly for eyewear lenses to reduce fogging problems from occurring in the first place. To adjust the fit of your face mask, consider reducing or enlarging the ear loops so that it fits more comfortably on your skin. The first and most crucial step is to ensure that your face mask fits snugly on your nose and cheeks, as an ill-fitting face mask can lead to increased humidity around your glasses lens. Here are a few tips to help you prevent getting your eyeglasses or sunglasses foggy when wearing a face mask: Overall, anti-fog spray is essential for anyone who wears glasses to maintain clear vision and keep them clean without worrying about them misting up. This can help keep your vision clear without needing frequent cleaning with harsh products like alcohol wipes. It also makes your lenses easier to clean. Moreover, anti-fog spray doesn't just prevent fogging. This layer prevents droplets from collecting together and blocking your vision.Īnti-fog spray will help reduce smudges from fingerprints or dust particles accumulating on your lenses over time. The surfactants gather on the surface of the lens, forming a thin invisible layer that keeps moisture away from the lens's surface. It contains surfactants, or molecules, with two parts, hydrophilic (attracted to water) and hydrophobic (repels water). Not only do foggy lenses make it difficult to see everything clearly, but they can also cause you to take off your glasses frequently, which can be uncomfortable and potentially irritating to the skin around your eyes.īest anti-fog sprays create a protective barrier on the lenses that repels water droplets that typically lead to fogging up. Until ANSI/ISEA creates uniform testing standards and guidelines for anti-fog eyewear, take the extra step to understand the type of anti-fog eye protection you’re providing to your employees and educate them on how to properly care for them.Įditor's note: This article represents the independent views of the author and should not be construed as a National Safety Council endorsement.Anti-fog spray is a must-have for anyone wearing glasses because fogging up can be an extremely annoying and distracting problem. Many of these are designed to reapply the anti-fog coating to the glasses while they’re being cleaned.Ĭertain situations, such as excessive sweating, definitely call for selecting premium anti-fog safety glasses. Many lens cleaning products (prepackaged wipes, sprays, etc.) are available to help maximize the life of the eyewear. Either the coating gets wiped off or the lens material gets scratched – or both occur simultaneously. Not only does this minimize the life of the coating, but it also can introduce debris and contaminants to the lens. It’s quite common for employees to take off the eyewear and wipe it off with a shirt, shop towel or something similar. When it comes to proper care of anti-fog treated lens materials, it’s important to understand how to clean and maintain the eyewear to maximize its wear life. These types of coatings, known as “hydrophobic,” simply repel and spread moisture and are generally less effective for long-term use, even if they’re properly cared for. Other coatings are applied topically to the lens. Known as “hydrophilic” coatings, these do not wash off over time. For example, some anti-fog coatings are chemically engineered to absorb moisture droplets, acting like a microscopic sponge. It’s important that users are properly trained on caring for the specific type of coating on the eyewear selected for them by their employer.

We know most definitely that not all anti-fog safety glasses are created equal. And it seems that all the major manufacturers now offer a “premium” anti-fog coating/material above and beyond the standard anti-fog coating of years past. Specifically in North America, manufacturers are marketing their anti-fog technology as industry-leading and outperforming the competition. The past three to five years have seen a rapid increase in anti-fog lens-coating technologies led by nearly every major eye protection manufacturer around the world.
