-Obito's not blind because of Hashirama's strong chakra -Indra's not blind because he has his father's strong chakra -Combining MS could bring forth a stronger, mixed chakra.

Could it be that the MS doesn't go blind from damage, but rather because it's starved of strong chakra? Like a muscle that becomes stronger with use, but doesn't get more energy to compensate?
