The human eye works like a living camera. Like a camera, the eye processes light and takes mental snapshots of images, which are then developed in the brain. In order to create vision, all parts of the eye must work together as a team. The cornea, the clear, film-like part of the eye, is the leader. When light enters the dark pupil of the eye, the cornea bends it. The refracted light travels to the lens behind the pupil. The lens changes its shape to adjust the focus on both distant and near objects. This process is known as accommodation.
The lens projects light from the outside world as an inverted image into the retina, which then acts like film in a camera and captures the image. The image is sent to the brain in the form of electric impulses to be developed.
