Itachi also said that Madara was the first to awaken the Mangekyou, and that he killed his clan as a test of power. Granted, as the story goes on there appear to be fallacies within Itachi's tale but how the Mangekyo works is never contradicted. It will lose its light naturally, the only one exempt from the rule is Obito because of the Senju DNA therefore blindness is a feature of the Mangekyo.
