Blindsight
by beaustiel
"Blindsight. My occipital lobe was damaged so there is no link between my eye and the visual cortex. Technically, the eyes still function, but my vision is black. So, I'm blind in the sense that I am unable to see objects placed before me, but I can guess, with a 98% accuracy, what it is, as in shape and size, and where it is. It's like, I can't see it but the information about the object is there, in my brain, I just have to really focus to access it. It's thought that a primitive visual system of the midbrain is at work." It's one of the few things, aside from volleyball, that Hinata understands so well.
