Can't stop fog!
I got this product, and it's not simple application.  You need to stray, cover liquid both sides of the eyeglass, let it dry, and then wipe it off with cotton cloth which I did.  In Chicagoland it's cold so when I come from outside to indoor with my mask and eyeglasses, it fogged so bad that I couldn't see and had to take my glasses off.
