5 tips to keep glasses from fogging up with a mask


Jul 21,2022

Now, in order to prevent the coronavirus, we always wear masks daily, but for who wear glasses may encounter the situation of glasses fogging. I bet you know how annoying it is!


Why does it happen?

The fogging of the glasses is generally caused by the large temperature difference between indoors and outdoors and the appearance of water vapor on the lenses, or the fogging of the glasses is aggravated by exhalation when wearing a mask.


How to prevent glasses from fogging up?


#1 Wear a mask correctly

After putting on the mask, pinch the iron wire on the bridge of the nose of the mask, and try to make the mask close to the bridge of the nose to prevent the breath from leaking out.


#2 Press the mask with glasses

When wearing glasses, press the glasses on the top of the mask. We can lift the mask up to the position below the eyes, then adjust the wire on the mask so that it fits tightly on the bridge of the nose, and finally press the glasses on the mask, in this way, you can keep them out of the way of the moist air as it escapes.


#3 Wash with soapy water

 Immediately before wearing a face mask, wash the spectacles with soapy water and shake off the excess. Then, let the spectacles 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.


#4 Shaving cream

Shaving foam can also solve this problem. Use shaving foam on both sides of the glasses, let it sit for a moment before washing it off with warm water.


#5 Use paper towels to prevent fogging

This technique is taken from an article published in 2011 by the Royal College of Surgeons of England. It includes the following steps: take out the disposable paper towel, fold it horizontally, and then place it between the skin and the mask (near the bridge of the nose).


BTW: Move or work when the vision is clear:

When the spectacle lens is fogged, do not move or stop the operation on your hands. You should remove the spectacles first, wipe it clean, or let the fog dissipate, and then start again.
