By likening the eye to a camera, elementary biology textbooks help to produce a misleading impression of what perception entails. Only in terms of the physics of image formation do the eye and camera have anything in common. Both eye and camera have a lens that focuses light rays from the outside world into an image, and both have a means of adjusting the focus and brightness of that image. Both eye and camera have a light-sensitive layer onto which the image is cast (the retina and film, respectively). However, image formation is only the first step towards seeing.                             obscure the much more fundamental difference between the two, which is that the camera merely records an image, whereas the visual system interprets it.
