Abstract: Surface having properties for reducing diffuse light due to water condensation, wherein the antifog means consist in atomic aggregates adhered to and dispersed over the surface, wherein the aggregates are selected among the transition metals and the silicon. It is also related to a method for obtaining a surface having properties for reducing diffuse light due to water condensation a wavelength selected in the range from 100 nm to 50 micrometers, comprising the steps of selecting the wavelength, obtaining a glass or polymer surface that has been subjected to optical polishing and adhering to the surface atomic aggregates which are selected among the transition metals and the silicon with a separation between them being lower than or having an order of the selected wavelength selected. Thus a durable antifogging surface is obtained.
