(a) The iris is the part of the eye that controls the amount of light entering the eye.

(b) The retina is the part of the eye on which images are formed.

(c) The ciliary muscles change the focal length of the eye lens.

Light passes through the front of the eye (cornea) to the lens. The cornea and the lens help to focus the light rays onto the back of the eye (retina). The cells in the retina absorb and convert the light to electrochemical impulses which are transferred along the optic nerve and then to the brain.
