Web25 nov. 2024 · The first step in the process of image formation in the eye is the entry of light into the eye. This occurs when light rays, which are electromagnetic waves, pass through the cornea, the transparent outer layer of the eye. The cornea helps to focus the light rays onto the retina, the light-sensitive layer of cells at the back of the eye. WebVisual cortex: This is where images received from your retina begin to get processed. The visual cortex has six layers and is the very beginning of your brain’s process of interpreting and recognizing what you see. Within these layers, depth perception is processed, and form, color, and motion are perceived.
