... Another possibility - which, admittedly, is still along those lines - is that the blast didn't do anything to Cinder since she's human, but it did cause a good deal of damage to the Grimm - who likely avoided death by virtue of the blast not being able to hit it directly.

Due to Cinder being connected to said Grimm, when the Grimm was damaged, this damage was reflected on Cinder.

In summary: Eyes don't hurt Cinder. Eyes hurt Beetlejuice. Beetlejuice is in Cinder. By hurting Beetlejuice, you hurt Cinder.

Unless one uses the "Salem said it was due to the Maiden powers, so the Maidens must be weak to SEWs!" card. Admittedly, the wording in that scene makes it sound like that. I've said it before, but to me the explanation appears to be that it petrifies Grimm life-forms, and if we assume the grim parasite is able to move around Cinders body freely, it probably isn't damaging her most of the time... but now imagine it's eel like structure changing to pumice/cement.... trying to escape the blast by burrowing through her body... starting in her head... ever tried rubbing yourself down with a pumice stone? now imagine that passing through your body.

Even assuming it has less mass than a dime that would do a shit ton of damage to everything, that she is still able to control motor functions and see at all is a miracle, and this all assumes the SEW powers did nothing to her.
