A method of coating without permitting the coating solution to flow onto the side surfaces or the back surfaces of the lenses in the operation for applying the coating solution onto the lenses. A lens 15 is spin-coated with the coating solution having a particular viscosity. A side edge portion 121 of a spatula 119 is brought into contact with an upper edge portion of a side surface 15a of the lens 15 before the coating solution fed onto the surface of the lens arrives at the peripheral edge portion of the lens. The side edge portion 121 of the spatula 119 is so arranged that the upper end side of the spatula is tilted toward the center side of the lens 15 at an angle of 5 to 35 degrees with the vertical line as a reference. The coating solution applied onto the lens 15 that is rotating adheres onto the spatula 119 but does not adhere onto the side surface of the lens 15.
