Whether you wear eyeglasses for fashion reasons or to see properly, chances are, you've found a way to comfortably and aesthetically fit them into your daily lifestyle. However, there's now a need for wearing face masks to help slow the spread of COVID-19 (Coronavirus). So, like a responsible citizen, you wear your mask but are then rewarded with totally fogged-up glasses. So, you ask, “What’s the deal with my glasses fogging up when I wear a mask?”
We’ve got that answer, along with tips to keep your eyeglasses clean and fog-free — even while wearing a mask.
Airflow and body heat can cause eyeglass lenses to fog. When warm air comes in contact with a cool surface, condensation may form. Have you ever walked into a warm building after being outside in the cold, and your eyeglasses became foggy? The same thing can happen when wearing a mask. When you wear a mask, you're breathing out warm air repeatedly. This air then sneaks out of your mask at the top and steams up your glasses.
And there’s proof: The Annals of The Royal College of Surgeons of England published a study that showed masks actually direct much of your exhaled air upward. Technically speaking, eyeglass lens "misting" occurs when your breath's warm water vapor lands on your cooler lenses and produces tiny droplets, which scatter light and reduces the ability of your lenses to transmit contrast (dark colors stay dark and light colors stay light). According to the study’s authors, these droplets form due to the inherent surface tension of the water molecules.
For most people, this eyeglass fogging is quite a nuisance. And, because there are nearly 200 million adult vision correction users in the U.S., according to The Vision Council, that’s a lot of eyeglass fogging going on — and annoyed spectacles wearers in the process. But, once you gain an understanding of the reason why eyeglass fogging occurs, solving the problem is more attainable.
Here are ways on how to keep your eyeglasses clean while you're wearing a mask.
Soap and water might sound like the most simple way to keep your eyeglasses clean, but you'd be surprised how many other "no-no's" people turn to when trying to clean their glasses. The steps of basic cleaning of your eyeglasses with soap and water, which provides a thin surfactant film, are:
If your mask is loose-fitting, it directs your exhaled air toward your eyeglasses. However, if your mask fits snugly, it directs the air out the sides or bottom of your mask instead, away from your eyeglasses.
One common trick doctors employ is to stick a strip of double-sided tape across the bridge of their nose before putting their mask on. If you add a double-sided tape strip between the bridge of your nose and the inside of your mask, it creates a better seal.
Or, you could also place an extra piece of masking tape or cellophane over your mask too. Some doctors swear by applying a bandage to the top of the mask and the nose.
Horizontally fold the tissue and place it between the top of your mask and your face, so it sits just over the bridge of your nose. The theory here is the tissue will absorb the moisture from your breath rather than hitting your glasses.
Adjusting your glasses, while obvious, is a great solution as it adjusts where your eyeglasses sit on your nose. Pushing your glasses up forward on your nose allows increased airflow, which can help with fogging. You can also try resting your eyeglasses over the top of your mask, creating a tighter seal.
There are commercial cleaners and anti-fog products you can try for keeping glasses clean when wearing a face mask. Here are a few examples:
Liquid castile soap is a highly versatile, gently formulated cleaning essential made with sensitive skin in mind. It's less astringent and effective for just about any cleaning purpose.
This is hand soap made with aloe vera, olive oil, essential oils, and other ingredients with no phthalates, parabens, or artificial colors.
This is an anti-fog spray for preventing fog. It's 100% ammonia and alcohol-free, safe on anti-reflective coated lenses, and made safe for all types of prescription eyeglasses.
Be sure you read all instructions on any product you decide to use since each product will be different. Always read the fine print as some anti-fog products could cause damage to lens coatings, such as their anti-glare coating. Some sprays and wipes may cause skin sensitivities as well.
Available in packets of 1, 5, 12, 20, and 100, these anti-fog wipes are popular among snowboarders, skiers, motorcycle riders, welders, and more.
