Not necessarily. Unless Obsidian added different visual appearances to armors depending on their condition and that's why the helmet is in such poor shape, I can't see the Enclave utilizing a helmet with cracked eye pieces.
Is it cracked? (I thought it was textured to look ... maybe slightly cat like. :shrug:)
**Edit:
Looks like it might just be grime..

@Talonfire #33: So can I. It looks like grunge/grime on the lens to me.
(and possible UV distortion/stretching on the right eye)
