First permanent anti-fog coating developed

Dr. Gaetan Laroche  and researchers of Universite` Laval created the first anti-fog coating that is permanent (instead of temporary). According to Dr. Laroche, the fog on glasses "consists of tiny droplets of water". Four layers of molecules were applied to make a compound known as polyvinyl alcohol stick to the surface of glass and/or plastic. The chemical bonds make the coating strong and durable. The surface's optical properties will not change when the coating is applied. Unlike this new permanent anti-fog "product", other anti-fog products are applied repeatedly because they aren't able to resist washing. The world at large will be affected if companies, especially those pertaining to optics, use this coating in their products. This great event will have a positive effect because it is ideal for car windshields, eyeglasses, and/or anything that requires eye vision. This anti-fog coating can make vision much easier in foggy areas.
