I haven't seen this anywhere, just recieved a Power Lens from a girl in a house on route 13, you have to go down the stairs below and to the left of Cobalion and past a turning ranger to get to it.
Maybe no more need to BP grind for EV training items?
EDIT: And I just found a second Hidden Hollow on Route 13 I heard about, it's near the entrance to Giant Chasm right above some stairs going down to a small patch of water.
