It's not a new problem as surgeons can attest to. Here are a couple of simple hacks on how to keep your glasses from fogging up when wearing a face mask. Why Do Glasses Fog Up When Wearing A Face Mask? Why do glasses fog up in when we wear face masks in the first place? Face masks direct most of the air we exhale upwards where it makes contact with the lenses of our glasses. Fogging occurs when the warmer water vapor from our breath condenses on the lens which are cooler. Tiny droplets form as a result and this scatters light and reduces the contrast of the lens. These water droplets form because of the surface tension between the water molecules. If there was a way to reduce this tension, it would cause the water molecules to spread out evenly in a transparent layer instead. Now that we know what causes our g
