The “garbage” comes from the processing of vitamin A, which is an essential nutrient for vision. If you think of the retina as the engine for vision, vitamin A is the fuel; it enables the retina to convert light into the electrical signals that enable vision. And just like gasoline, which produces exhaust, vitamin A, when metabolized, leads to undesirable by-products.

It works like film or digital sensors in a camera by converting the light that enters our eye into electrical signals. Those signals are sent over the optic nerve to the back of the brain, where they are used to create the images we see.
