Abstract: A method for controlling a manufacturing device used in an optical lens manufacturing process. The method including providing optical lens data, the optical lens data representing the nominal and effective values of at least one optical lens parameter of an optical lens manufactured according to a manufacturing process using a manufacturing device, providing manufacturing data identifying at least the manufacturing device used to manufacture the optical lens, determining the difference between the nominal and effective values of the at least one optical lens parameter of the optical lens, determining a recommended value of a manufacturing parameter of the manufacturing device identified by the manufacturing data, the recommended value of the manufacturing parameter being determined based on the difference between the nominal and effective values of the at least one optical lens parameter.
