Medical masks normally have a metal strip that can be shaped to your nose. If you have a homemade mask, use a pipe cleaner to mimic the metal strip.
You can also try a twist-tie, paper clip or aluminum foil in place of the pipe cleaner, WBBM reported.
Also, tighten the fit. Adjust the ties or ear loops so the mask is snug, the Times reported.
Stop leaks with tape -- either medical tape, athletic tape or even a Band-Aid. If you have duct tape, put it down! Don’t use tapes like the silver-fix-all or packing tape. They could cause skin irritation.
You can also use your glasses to block the airflow by pulling the mask higher on your nose, and under the glasses. Remember it may not work for all styles of eyewear.
You can also keep them from fogging by washing the lenses with soapy water and letting them air dry. The film stops water molecules in your breath from forming on the lenses, the National Institutes of Health suggested.
You can also try baby shampoo, toothpaste and shaving cream, the Times suggested.
But some say you may want to stay away from those treatments because they could potentially damage the lenses depending on what coating is already on them, WBBM reported. You could also irritate your eyes.
There are also commercial anti-fogging treatments available on the market.
But don’t be surprised if they don’t work. There are coatings on some lenses that are resistant to the treatments.
