my question:

how does, "using susanoo with MS" damage the eyes? if the MS is only needed to activate it and than it an be used even without any eyes at all, how does it affect the eyes? cant a uchiha tak his eyes out and train susanoo until he reaches PS and than does his eyes back into his skull?
