How to Wear a Mask Without Your Glasses Fogging

Wearing face masks has become a norm as people around the world are taking safety measures to prevent the spread of coronavirus.  For the most up-to-date information on COVID-19, please visit the online resources provided by the CDC, WHO, and your local public health department.

For those who wear glasses, it may seem next to impossible to properly wear a mask without your lenses fogging up. Believe it or not, there are a few ways to prevent foggy glasses you can try out the next time you put on a face mask. 

Before we get to the solutions, however, you might be wondering:  Why do glasses fog up when wearing a mask?

The answer is pretty simple: when you’re wearing your mask, warm breath exits from the top of your mask, sticking to the cool eyeglass lenses. Anytime warm air hits a cool surface, this creates condensation or fog. Think of when you open a hot oven or walk from a cool building into the summer heat. 

So, how do you avoid foggy glasses when wearing a mask?

Make sure your mask fits properly. A mask that fits snugly over your nose can prevent spectacle fog by preventing the warm air you breathe from escaping to your lenses. A properly fitted mask allows breath to escape through it, not from the top or sides. A low-stick sports tape can help secure your mask so that it stays in place at all times. 

Depending on the shape and size of your glasses, you may be able to decrease the amount of fog on your lenses by pulling your mask higher on your face and placing your glasses on top to prevent air from flowing up. This method is best for those who wear large frames. 

If all else fails, you can try using anti-fog wipes or sprays. These products tend to be on the expensive side, so be sure to do your research and confirm that the product you’re purchasing works with the specific type of lens you wear.
