Man born blind

Does anyone have an explanation for John 9:2 other than a belief in some
sort of transmigration of souls or reincarnation?  It is the tale of the
"man born blind," concerning whom the disciples asked, "Hrabbi, tis
hEmarten, houtos E hoi goneis autou, hina tuphlos gennEthE?"(Rabbi, who
sinned, this man or his parents, so that he was born blind?).
