Q: I know I'm not the only one having trouble with my glasses fogging up when I wear a face mask because I've seen other stories in the newspaper. Can you go over some of your suggestions?
A: When we wear a mask, warm breath can escape through the top edges, along the tops of our cheeks. When the hot air lands on cooler lenses, it creates condensation on the surface and a foggy film. Cold weather makes the problem worse, so this could become a bigger problem in the coming weeks.
Here are some tips to stop the fog.
* Improve the seal of the mask around the top of your face.
* Mold your mask using the bendable metal strip across your nose. Pipe cleaners can be used.
* Pull your mask up a little higher on your nose.
* Apply anti-fog substances to coat your lenses.
* Wash lenses with soapy water.
* Use commercial anti-fog products.
