Abstract: A coating solution is injected from nozzles in the horizontal direction to coat, with the coating solution, lens surfaces of a spectacle lens substrate so arranged as to orient an optical axis in the horizontal direction. The spectacle lens substrate is rotated at a first rotational speed about the optical axis serving as the rotation center, and the coating solution is spread on the lens surfaces by the centrifugal force. The spectacle lens substrate is rotated at a second rotational speed higher than the first rotational speed to blow away an excess of the coating solution from the spectacle lens substrate by the centrifugal force. Highly uniform films can be formed on the lens surfaces of the spectacle lens.
