How+your+Eyes+Work

= = = How does the eye work analogous to a camera?? = = =



==**Scientists compare the human eye to a camera. Both provide vision. The cornea behaves like camera’s lens. Both receive the light or the rays and bend them through pupil and round opening in the centre of the colored iris. The back of the eye is connected with the retina, which is similar to the film of the camera. The photoreceptor nerve cells of the retina change the light rays into electrical impulses and send them to brain. When all of the eye parts work well, then light is converted to impulses and sent to the brain where an image is perceived.**==
