Written by gino

Do you know how to prevent your glasses from fogging up when you wear a face mask? It’s actually quite simple and could “save your life” in COVID weather! We’ll discuss what causes your glasses to fog up and three ways to prevent annoying water clouds from forming on your glasses. Stay safe…and fog free!

What causes your glasses to fog up

There are several reasons why your glasses can fog up when you wear a mask. The most common reason is that your breath is hot and humid and when it touches the cold surface of your glasses, it condenses into water droplets. The other possibility is that you are not wearing your glasses properly. If they are not placed close enough to your face, warmer air can escape through the top and bottom of the frame and cause condensation. Finally, some materials used in goggles (such as cotton) can release moisture when they come in contact with your face. All of these factors contribute to the formation of water droplets on your glasses, which can obstruct your vision and be quite annoying

But don’t worry, there are several ways to prevent your glasses from fogging up!

How to prevent fogging?

Wear your protective mask properly

It’s essential to avoid fogging up your glasses. Make sure the mask completely covers your nose and mouth. Once you have your mask on, pinch the wire at the top of the mask so that it fits snugly around the bridge of your nose. This will create a seal that will prevent your breath from escaping and fogging your glasses. If you don’t have a holding wire at the top of your nose, you can try placing a small strip of tape on the bridge of your nose (the ridiculous doesn’t kill ^^).

If you find that your glasses are still fogging up, you can try the other methods below.

Use anti-fog products

There are a number of anti-fog products on the market that you can use to keep your glasses from fogging up.They usually come in the form of wipes or sprays . Simply wipe or spray the solution onto your glasses and let it dry. You may need to re-apply these products throughout the day, depending on the following factors:

  • The type of product you are using
  • The humidity level
  • How often you wear your mask
  • The natural oils in your body

Use soap and water

A more DIY approach is to use soap and water. Wet your glasses with soap and water, then dry them completely. The thin layer of soap will prevent your breath from fogging up your glasses. You can also try using a small amount of toothpaste on your glasses.

Wash your masks regularly

Remember to wash and dry your masks before reusing them

To prevent your glasses from fogging up, be sure to wash your mask regularly. A clean mask will keep your glasses from fogging up more than a dirty mask. Wash your mask in warm water with soap and let it dry completely before wearing it again.
