You joke, but that’s kindof a thing.

The occipital lobe is responsible for us being able to proccess and turn the info our eyes gather into what we see. Severely damaging is can make us be unable to process the info our eyes collect and be effectively blind. Even though there is nothing wrong with our eyes.

You can have a stroke in your occipital lobe and just wake up blind. Or get hit in the back of your head and lose your vision.

Basicly forget how to see.
