Diagram:

                                    

STRUCTURE:

STRUCTURE	EXPLANATION
CORNEA	Transparent Convex Lens that Refracts Light
IRIS	Pigmented and Controls How much Light Enters the Pupil
LENS	Transparent Disc that Focuses Light onto the Retina
RETINA	Contains Rods (Detects Black and White) and Cones (Detects Colour) that Detects Light
OPTIC NERVE	Sensory Neurons that Sends Impulses Between the Eye and the Brain
PUPIL	Hole that Allows Light to Enter the Eye to be Focussed on the Retina
CILIARY MUSCLES	Ring of Muscles that Changes the Shape of the Lens to Focus Light on the Retina
