The first thing about vision that isn’t explained is that fact you’re conscious of what you see. That’s an example of, “the hard problem,” in consciousness studies, or philosophy of mind: the very existance of consciousness is unexplained.
But then is the question of, “where are the images that you’re seeing?” You’re seeing a 3 dimensional, colored world.

The conventional view is that all that’s inside your brain. [They believe] You’ve got a virtual reality display somewhere inside your head, which includes me, and the rest of this room and everybody else here — it’s all in your head.
