Remember Kakashi hasn’t had use of his Mangekyo Sharingan for the entire time he’s had it available, due to his poor stamina and chakra. However, he is truly losing eyesight, this is confirmed by Kakashi himself. Why Obito’s right eye is not yet blind even with all his use of his Mangekyo, is unknown.Is it possible that Obito fused his eyes with Sharingan he collected from the massacre to restore his vision? Since most of those eyes most likely did not unlock the Mangekyou Sharingan it wouldn’t have upgraded Obito’s eyes to the Eternal Mangekyou Sharingan. Or am I getting my understanding of Sharingan fusion mixed up?

When you make an Eternal Mangekyo Sharingan, you are removing your previous set of Mangekyo Sharingan and adding the spare pair instead. The eyes then morph into a version of both yours and the spare’s Mangekyo design, but they are still the spare set. For example, the eyes in Madara’s head are Izuna’s, and the eyes currently in Sasuke’s head are Itachi’s. The Sharingan also can’t act as a spare, it has to be a Mangekyo Sharingan of some kind.

The Sharingan Obito collected from the Uchiha Massacre are meant to act as replacements for his normal Sharingan left eye should he need to use it for Izanagi.

Obito’s Mangekyo Sharingan’s irregular vision is most likely caused by Hashirama’s cells present in his body. We are already aware that Hashirama’s cells have positive affect on Mangekyo eyes, as Danzo used it to increase the frequency he could use Kotoamatsukami through Shisui’s Mangekyo Sharingan.

that is the general theory on the situation, but it isn’t confirmed.

  1. The answer could be much more simple than you think.. Remember that since kekashi is not the original owner of the sharingan eye he had to implant it in his head and since he implanted the eye it already acts as a spare to his original eye. Apparently it doesn’t matter that his original eye was not a sharingan, the fact that he implanted it unlocks it’s eternal potential. Even if he isn’t able to use mangekyo at the time and personally I think that the eyes are still linked even when in 2 different bodies as kekashi did not kill a best friend or family member in order to unlock his mangekyo ability… As for obito, remember that madara rebuilt most of obito’s body which included his sharingan eye there are a few things madara could have done to awaken his sharingan during this process.

  2. lol no
    seems u guys didn’t watch the anime
    obito & kakashi both awakened the mangekyo at the same time – watching rin’s death
    kakashi couldn’t with stand its power he just fainted
    obito left killing everyone present there
    where as ems completely needs genetic support
    & the reason they weren’t blind
    kakashi couldn’t use it much n wen he did use mangekyo he suffered blindness up to some period of time
    obito – just cuz of harshirama cells
