Do Flashbangs count as Blinding?

I've been working on the tome challenge of Get 6 Blinds for a bit, and managed to finally get four of them with all of the flashlights I had at that point. Out of them, I decided to use Blast Mine and Flashbangs to try and get it done... except I've flashbanged killers three times now (they cried out, and once was a save) and no credit has gone towards the challenge. Does it only count as a stun and not a blind?
