Eye Functionality
- The lens accomplishes the remaining focusing of light into images.

- The optic nerve transmits electrical signals from the eye to the brain, enabling visual perception.
- Images fall and get processed through the retina.
- The iris keeps the eye essentially light-tight except on the eye's optic axis, regulating the amount of light that enters the eye.
