Clean glasses and a mask are a combination that creates problems, as the glasses blur with each exhalation. However, there are some ways to stop this annoying situation.
Although face masks help to prevent the spread of coronavirus, those who wear glasses experience a big problem first hand: the glasses dim every time they exhale, because water vapor from the mouth rises to the eye due to the mask.
Many people who wear glasses are so irritated or intolerant that they take off the mask and so the coronavirus spreads, putting both themselves and those around them at risk!
A study published in The Annals of The Royal College of Surgeons of England provides a simple solution to the problem. The authors recommend that you wash your glasses with soapy water before wearing the face mask. Then let them air dry or gently dry the lenses with a clean cloth.
With this method, the lenses will not blur when you wear the mask and glasses, the study says. Why; Cleaning the lenses with soapy water leaves a thin coating on the lens, which reduces the "inherent surface tension" and pushes the water molecules to form a transparent layer.
To avoid damage, do not clean your lenses with products such as baby shampoo, toothpaste or shaving cream, the researchers say.
A common trick used by doctors is to stick a piece of double-sided tape to the bridge of the nose before wearing a mask. "If you place a double-sided tape between the inside of the mask and the bridge of your nose, you will achieve a better fit on your face and thus reduce the water vapor that will leak upwards when you exhale. You can also place an extra piece of cellophane or duct tape over the mask.
By the same token, choose a mask with a flexible material (eg wire) at the top seam, and bend it to fit the shape of your nose and cheekbones as best you can.
If your glasses have nose mounts, you can modify them so that the frames sit a little further away from your face. This will allow hot air to escape instead of being trapped between your face and the lenses of the glasses.
This change may slightly change your vision if you wear glasses. If this happens, you may need to hold your head at a different angle to compensate for the change in vision.
There are various sprays, gels and wax products that you can apply to the lenses of the glasses before wearing them. These help disperse tiny water droplets when wearing a mask.
Do not use fog lamps intended for cars or other purposes, as they may damage your lenses.
It's a little weird, but try to exhale down: Keep the upper lip further out than the lower lip. So when you blow the air you will send it down, like playing the flute!
