An anti-fog diving mask contains: at least one lens and at least one anti-fog film, and each of the at least one anti-fog film corresponds to and adheres on an inner surface of each of the at least one lens. Said each anti-fog film is transparent and is made of a hydrophilic substrate so as to absorb water molecules, thus avoiding foggy sight as diving in a temperature difference under water.
