We see some deep holes there in his eyes. Seems deep in. If it was blinded, then there would just be damaged eyes. This is full on destruction of the eyes. The video showed him falling to the ground dead, he isn't breathing and isn't coming back.
 * SCREAMING INTERALLY* I LITERALLY-showed a video on this thread showing he was still breathing! And they weren't deep enough for a kill, just deep enough to blind.
