WHY DOES WEARING MASKS DURING THE CORONAVIRUS PANDEMIC CAUSE THE LENSES TO FOG UP?
There’s a very simple science behind it. When we breathe, the warm air escapes from above our mask.
This lands on the cooler lenses of the glasses. That creates condensation. This manifests in the form of fog on glasses.
There are various ways to prevent this from happening. The first one is obviously to prevent your breath from escaping towards your glasses. This would require a better fit. That way you would need to adjust the straps or use some material to fill in the space left by the masks. Taping your mask to the bridge of your nose is also a solution. It can be adhesive, medical or athletic tapes.

The third way is to pull the mask higher on the face and use the weight of glasses on top of the mask to block the flow of air.
In addition, there are several home remedies. Washing glasses with soapy water and letting them air dry can be helpful. That’s because the soap acts as a surface-active agent or surfactant and leaves behind a thin film preventing fog.
