This video explains how the human eye processes light to create vision. It covers the journey of light as it enters the eye through the cornea, passes through the pupil controlled by the iris, and is focused by the lens. The light then reaches the retina, where rods and cones convert it into nerve impulses. These impulses travel via the optic nerve to the brain's occipital lobe, which processes the images. The video concludes with a call to subscribe for more educational content.
