An American neurosurgeon posted his advice on keeping eyeglasses from fogging up while wearing a face mask and it is genius – all it takes is a band-aid!
In his tweet he says he “Learned it in the OR. Feel free to share, it may save lives!”
If you try it, he suggested putting the cotton part of it on the bridge of the nose with half of it on the mask and the other half on the face … and it works like magic.
