Is it just a flashlight or is it like a cyborg eye that he can see out of?
It’s a cybernetic implant… also it’s his eye. So yes he sees with it.
It moves around with his normal eye and all. Plus, all the hunters already have flashlights mounted and I don’t see why he’d have a flashlight there looking anything like that, and the tech id advanced enough.
I always assumed it was his cybernetic fully functioning eye.
