When you wear a mask, how do you keep your glasses from fogging up?

5th January, 2022.      //   General Interest  // 

It’s a nagging issue: your glasses fog up as soon as you put on your cloth face mask and head out the door.

However, there is a quick cure for this that will only take a minute or two. Only soap and water are required.
This advise comes from the medical journal Annals of the Royal College of Surgeons of England, courtesy of two doctors. And if it works in the emergency room, it will undoubtedly work in the grocery store.

Why does fogging occur, and how does this solution work?
Because the mask sends your air upward rather than in front of you, your specs fog up, which is helpful for preventing disease transmission but bad for someone with poor vision.

Soap and water act as a veil on the lenses, reducing surface tension. It’s because of this magic mix that the water molecules from your breath are evenly distributed rather than clustering on your lens, making it harder to see.

1. Always wash your hands with soap and water first

Remember, scrub for 20 seconds (two rounds of “Happy Birthday”) before you rinse.

2. Wet your glasses, then lather some soap on the lenses

There’s no time limit for lens scrubbing, so be gentle and thorough.

3. Rinse your glasses under warm water

Don’t leave any soap suds on your lens — if the fog didn’t obstruct your vision, bubbles certainly will. They’re not fun to rinse out of your eyes, either.

4. Gently dry your glasses with a clean towel or lens cloth

Avoid using a towel that may scratch your delicate lenses.
