The eyes don’t deliver imagery at all. They deliver a signal that’s more like a million track audio recording. It doesn’t become imagery until interpreted by the brain.
If you hooked a camera up to a newborn’s ears and microphones to their eyes, the baby would learn to see imagery though their ears and hear sounds through their optic nerve.
The data quality would be horrible, but they’d still see and hear.
It’s the structure of the world (and our relationship to it) that creates meaning in our minds, not the structure of our brain. Although our brain is structured to get clearer signals through certain parts.

For many on HN, that's the way they are used to thinking of imagery, as a big array containing information about how strongly a grid of sensors was stimulated.
