Query: Look Ma! No More Fog

I have a woodworking shop. I could not wear a dust mask because my glasses would fog up. I bought this item and it seems to work well for me. I have worn a dust mask and a pair of over the glasses goggles. After applying this to the surfaces of the goggles and the glasses I have not had a problem with fog.Red Crane
