Right. I know that. Because Sasuke transplanted Itachi's nearly blind eyes into his own and suffered no issues. Any blindness that was once suffered disappears upon the attainment of the Eternal Mangekyo.

How that works, I have no idea. It would seem to me that damage done is damage done, but I guess it's magic. They ain't gotta explain shit. Frankly, I would have liked an explanation, but whatever.

And yeah, since Indra was born of Hagoromo, he would have had some of Hagoromo's ability. Frankly, I always got the impression that while Asura inherited the Six Paths chakra and Wood Release (but not the Rinnegan), Indra inherited his ocular powers, namely the Sharingan but again, not the Rinnegan.
