WELCOME TO RANDOM, LOLOLOL. 
It’d be funny if they just used like… a glass eyeball as an implant. Can you imagine what it would be like if someone exhumed your body?
“wtf is this doing down here? Shouldn’t it be in the skull?”
Wow, imagine having a glass eye just implanted anywhere in your body, but have it so that it shows and it looks like a third eye… but like in your torso.
