Homemade face masks are ending up being the norm as the coronavirus epidemic continues to damage the United States, with some states– namely New York, New Jersey, Connecticut, Pennsylvania and beyond– now requiring them in public. But if you are a glasses wearer, you may have seen that using a face mask can trigger your lenses to fog. What can you do to prevent this?
Thankfully, there seems a simple service. In a 2011 study from the Annals of the Royal College of Surgeons of England, researchers advised washing the glasses with soapy water “right away” prior to wearing a face mask.

After shaking off any excess water, “let the eyeglasses air dry or gently dry off the lenses with a soft tissue prior to putting them back on. Now the spectacle lenses need to not mist up when the face mask is used,” they composed.
Wondering why this works? The scientists discussed this. When using face masks, air exhaled from your mouth moves upward and enters into contact with the lenses, eventually triggering them to fog.

More particularly, “The misting takes place from the warm water vapor content condensing on the cooler surface of the lens, and forming small beads that scatter the light and decrease the capability of the lens to send contrast,” they wrote.
