Reduce Eyeglass Fogging in Cold Weather
If you wear glasses and have tried to use a dust mask while breathing hard in cold weather, you know that it won’t be long before you can’t see. Even if you buy the nicer dust masks with two straps and the metal nose clip, you still end up with a gap across the bridge of your nose. The warm, moist air quickly condenses on your glasses.
Here’s a way to prevent this problem. First, trim the extra material from the top of the dust mask just above the metal clip, as shown in the drawing at right. Put on the dust mask, and adjust the clip. Cut a 1-1⁄2-in.- to 2-in.-long strip of 1-in.-wide waterproof medical tape, then place it across the top of the dust mask below your eyes.
The waterproof tape will not come off when you sweat, and it will not allow the air to come up under your glasses. I’ve used this method a lot, and it has never failed me.
