The invention is suitable for the technical field of optical lens manufacturing, and provides a film coating method and device for an optical lens and a product, and the method comprises the steps: obtaining compensation data based on the radius of the optical lens and the thickness of a first film layer of the optical lens; obtaining a second continuous radius in a second preset radian based on the maximum value in the compensation data and the first preset radian; based on the second preset radian and the second continuous radius, obtaining a preset number of centrosymmetric surface-shaped mask layers based on the optical lens; and based on a preset evaporation source and the surface-shaped mask layer of the first preset rotation mode, coating is carried out on a preset mirror surface of the at least one optical lens of the second preset rotation mode for a preset time to obtain a coating layer of a first film layer thickness. According to the invention, the coating layers with different preset thicknesses
