Good product to have in these times.
My wife has glasses. They fog up when she wears a face mask against Covid 19.  She has to wear a mask many hours a day because she works in a hospital. The anti Fog Spray clears her glasses so she doesn't have to keep wiping them. I have seen a number of people in indoor settings exposing their noses because their masks fog their glasses. Wish everyone would use this product and cover up when appropriate.
