Bundles of light coming from an object fall on the retina upside-down. Here, the image is converted into electrical signals and transmitted to the centre of vision at the back of the brain. Since the brain is insulated from light, it is impossible for light to reach the centre of vision. This means that we view a vast world of light and depth in a tiny spot that is insulated from light.
Stimulations coming from an object are converted into electrical signals and cause an effect in the brain. When we "see", we in fact view the effects of these electrical signals in our mind.
