The original Shinju doesn't have an eye. The entity summoned by Obito while he was a jinchuuriki was a recreation of the Shinju (or a Tailed Beast Mode "replica," as the Jinchuuriki Forms article calls it) and not the actual thing, due to it temporarily co-existing with the real TT when Madara revived it again.
