An automatic effect of awakening these eyes is that the user's vision is fully and forever restored from the damage done to it by awakening and using the Mangekyo Sharingan. Just like the standard one and the Sharingan, it has a red iris. At such a point, the Eternal Mangekyo Sharingan awakens with the appearance of being a mixture of the user and the relative whose eyes he transplanted Mangekyo. this dojutsu can only be awakened by a user of the standard Mangekyo Sharingan transplanting the eyes of a relative who has also awakened that dojutsu.
The Eternal Mangekyo Sharingan is the second strongest dojutsu kekkei genkai of the Uchiha clan, being a more powerful variant of the Mangekyo Sharingan.
