No thanks to Covid-19, we’re now all used to wearing a face mask when stepping out of the house. While slipping the mask on is easy (as long as you do it right), bespectacled individuals may come face to face with a pesky problem others don’t – foggy glasses. The science is simple. You breathe, the air slips out from your mask, and your warm breath mists up your comparatively cool glasses.
You may have already tried your best at shaping your mask to fit your face snugly, to no avail, and we understand. Thankfully, there are still some other tricks out there for you to try so you don’t have to endure foggy vision as you’re out running your errands. Here are six of them:
A study published in 2011 in a medical journal, Annals of The Royal College of Surgeons of England, recommended washing spectacles with soapy water as a solution for misty glasses when wearing a mask.
“Immediately before wearing a face mask, wash the spectacles with soapy water and shake off the excess,
“Then let them air dry or gently dry off the lenses with a soft tissue before putting them back on. Now the spectacle lenses should not mist up when the face mask is worn.”
Washing the spectacles with soapy water will create a “surfactant film” that “causes the water molecules to spread out evenly into a transparent layer can help keep glasses from fogging.”
Though the solution isn’t instant, one must do it repeatedly a couple of times a day. We assume every time before wearing your mask, in order for it to take effect, which can also be quite a hassle.
Shaving foam and cream is another easy trick you can try at home. Steal a dab of shaving foam or cream from the men at home, place it on your finger and rub it on your lenses.
Leave it on till it dries, then clean it with a soft fabric or microfibre cleaning cloth, so it doesn’t leave scratches on your glasses.
For a quick solution, get an anti-fog spray that is commonly used for swimming, diving and snorkelling to prevent condensation which can cause disruption to water activities. The concept behind this is quite similar to how soapy water works.
Make sure the chemicals from the spray has been properly cleaned before putting your spectacles on again so as to not cause irritation to your eyes.
If you’re making your own cloth masks or are using the reusable mask issued by the government, besides using a thin wire to secure the gap between the nose, there are other materials you could use that might offer a better seal.
Alternative materials that are less flimsy include metal fasteners found in files, aluminium foil that has been folded lengthwise, or a pipe cleaner.
You might have to secure these materials down or pad it up with more cloth so that it doesn’t stick out or poke you.
The Tokyo Metropolitan Police Department in Japan suggested folding down the top portion of the mask before wearing it to prevent condensation on the glasses.
However, this method could reduce the area covered by the mask, and compromise the effectiveness of keeping out respiratory fluids that could potentially spread the coronavirus from an infected patient.
Alternatively, the other tip that the Tokyo Metropolitan Police Department has shared is putting a piece of folded tissue paper where the nose wire is. This will help to absorb any moisture that escapes the mask before touching the surface of the lenses.

Nicole Jochym, a third-year medical school student at Cooper Medical School at Rowan University suggested a simpler method as compared to the ones listed above.
She told The Inquirer Philadelphia: “If you push your glasses forward on your nose a little bit, it should help with fogging,” explaining that, “It makes for more airflow between your face and glasses.”
Though, Samir Mehta, chief of orthopaedic trauma and fracture care at Penn Medicine, noted that people who wear glasses are already “used to where they sit on their face,” and doing so may alter your vision.
