A method of optical-film treatment in which coating troubles apt to occur in the formation of a functional layer, e.g., an antireflection layer, on a continuous film by coating fluid application, such as transverse thickness-difference lines, coating streaks, and tailing, are diminished. The method of optical-film treatment comprises wetting with a liquid a continuous film which is being continuously conveyed, continuously rubbing the continuous film with an elastomer, and then removing the liquid from the continuous-film surface, and is characterized in that the surface of the elastomer has a coefficient of static friction of 0.2-0.9.
