To provide a spectacle lens manufacturing system and a method of manufacturing a spectacle lens, as well as a program and a recording medium therefor, that can meet various demands for marking and by which customers can confirm the outer appearance or the like of the spectacle lens. In a spectacle lens manufacturing system, after acquiring mark information and lens information with a terminal, these mark information and lens information are output to a calculation server, and a determination unit of the calculation server determines whether or not marking is possible. If the determination unit determines that it is possible to mark, it is judged whether or not a spectacle lens is manufactured based on a simulation image of the spectacle lens displayed on an image display unit of the terminal, and if it is determined to manufacture the spectacle lens, a processing information-generating unit of the calculation server generates processing information for the spectacle lens.
