En español | Masks are a crucial way to decrease the spread of COVID-19, but these mouth-and-nose coverings cause a few nuisances, including fogged-up eyeglasses.

When it’s cold, your breath puffing up through the top of the mask clouds the lenses, especially when you go from the chilly outside to the warmer indoors and the mask isn’t tight around your face.

The effect is similar to how a hot shower’s steam fogs up a cool bathroom mirror. The easiest, and least expensive, way to ensure that your glasses don’t fog is to wear a snug-fitting mask with a tight seal across the top that prevents your breath from escaping, says Moran Roni Levin, M.D., assistant professor of ophthalmology at the University of Maryland School of Medicine.

But there are other options, including antifog lens coatings, sprays and wipes.
