How to stop your glasses from fogging up when you wear a mask
It’s an annoying problem: As soon as you strap on a face mask and head out the door, your glasses fog up. But there’s a simple fix for that, and it’ll only take a minute or two. All you need is soap and water.
This trick is used by doctors who have to perform precision surgeries while wearing a mast. So if their defogging trick can work in the operation theatre, it can certainly work in the grocery store.
Why fogging happens, and why this solution works
Your specs fog up because the mask directs your breath upward instead of in front of you, which is good for preventing disease transmission but bad for anyone with weak eyesight.

Soap and water act like a cloak that reduces surface tension on the lenses. This magic mix allows the water molecules from your breath to distribute evenly, rather than cluster on your lens in a way that makes it difficult to see.
How to stop your glasses from fogging up with soap and water
- wash your hands with soap and water first
- Wet your glasses, then lather some soap on the lenses
- Rinse your glasses under warm water
- Gently buff your glasses with a clean towel or lens cloth
- Enjoy your clear specs, and go on your way!
Although easy, this might just be a temporary solution and needs to be repeated couple of times a day
Other ways to prevent fog on your glasses
Choose glasses that sit far from your face

The main problem with glasses fogging up is the lack of circulation during intense hot and cold climates. Choose a pair of prescription glasses that sit far from your face to increase circulation.
Use a dab of shaving foam

Try using a tiny dab of shaving foam to polish your lenses with. Let it dry before buffering off the excess and this should create a clear layer over your glasses to protect from the changes of heat and cold.
