Current events have required more and more people to wear face masks for the protection and safety of themselves and those around them. There is only one problem: those who wear glasses face another difficulty – their glasses become blurred when they wear a mask. This is a fact of life when you wear glasses – they get foggy all the time. Temperature changes, face protection equipment and winter equipment are some of the common causes of goggles. Here are some helpful tips on how to deal with this situation.
Why are the glasses blurred?
The glasses are blurred for one reason, and that is changes in temperature. If you are outside on a cold day and enter a warm and humid room, your glasses are blurred due to water vapor in the air condensing on the cold glass. Another contributing factor is your breath. The mask you wear directs your breath upwards rather than outwards. Your breath is also quite humid because the inside of your mouth and lungs are moist. The warm, moist air you exhale hits the relatively cold surface of your glasses and condenses on them. The drops that form on your glasses stay there because of the so-called surface tension and should be wiped or evaporated.
Option 1: Properly position and secure your mask
As we mentioned, the reason why the glasses are blurred is the moisture from the breath. Most of the masks we wear are cloth or paper. You need to check if there is a metal or plastic fastener above the mask that adapts to the nose. When you attach the mask correctly to your nose and face, you minimize the breath going up and prevent your eyes from blurring. You can combine this with adjusting your breathing. There are also more progressive masks, for which it is enough just to attach them nicely to the face. Sometimes the body generates moisture from the sweat itself, and not just from the breath, which brings us back to the fact that in some situations we have to control our breathing and look at other options.
Option 2: Use a tissue or band-aid
This is primarily an option for paper or cloth masks that do not attach well to the face. Take a paper towel and fold it, place it on top of the mask before putting it on your face and squeeze it down. This gives you two benefits. The first benefit is that, like an absorbent cloth, the handkerchief will block and absorb moisture from your breath that would otherwise go up and blur your glasses. The second benefit is that it provides a softer surface than the mask itself and is more comfortable to wear. You can do the same with a patch.
Option 3: Use anti-fog glass
Nowadays there are many anti-fog agents for glass, helmet visorс, glasses. They all work the same way: apply them to the glass and wipe them, leaving an invisible layer that helps reduce surface tension. In any case, their effect is longer lasting during the day.
Option 4: Soap and water
Wash your glasses before applying the mask. Use soap and water to wash them and instead of wiping them with a cloth, shake off the excess drops and let them air dry. You need to put a thin, invisible layer of soap on your glass. This will prevent moisture from accumulating on the glass. Why does it work? The answer lies in the interaction of soap and water. Water, in pure or mostly pure state, has a high level of so-called surface tension. You may have seen water stay on the surface instead of spilling on the surface. This is because it keeps its surface tension in place. When soap is mixed with water, that surface tension is disturbed. Applying a thin layer of soap to the glass makes it harder for moisture to condense on the glass, although it is not entirely impossible. Soap during the day can reduce this effect, so you will have to repeat this procedure more often. Yes, it is an effective solution, but it is not long-lasting. Another similar product that has the same effect is shaving foam. A very thin layer of foam can prevent moisture on your glass.
