Fogging of glasses is a widespread and well-known problem still searching for a solution. It occurs on the surfaces of objects that are colder than their humid environment. For example, this is the situation for eyeglasses if the wearer walks from the cold outdoors into a warm room. Further examples for glass surfaces affected by fogging are helmet visors, diving goggles, car mirrors, or windows in general. Fogging results from water that condenses in form of small droplets on the surface. These droplets scatter the transmitted light, and thus cause blurred vision through the glass (see Figure 1 A and B). Anti-fogging surfaces avoid the formation of scattering droplets on a surface. This is achieved by improving the wettability of the surface such that the droplets are spread completely across the surface (Figure 1 C). The challenge is to find the optimal surface morphology of glass to achieve high wettability and minimal scattering at the same time.
