Structure & Function: use book pgs Cornea: clear tissue that covers front of eye. Pupil: opening through which light enters the eye. Iris: colored part of eye, controls amount of light entering eye. Lens: focuses light on retina. Image is upside- down. Retina: layer of light sensitive cells in back of eye – respond to light. Rods & cones send electrical impulses to optic nerve. Optic Nerve: sends signals to brain.

 Light is reflected to eye.  Light enters pupil.  Lens refracts light to retina.  Retina sends signals to optic nerve.  Optic nerve sends signals to brain.
