Sends impulses to the brain collected by sensory neurones when light-sensitive cells in the retina are stimulated.	Optic Nerve	78%
Made up of muscles which contract/relax to control the size of the pupil, as well as how much light enters the eye.	Iris	75%
A transparent area of the sclera at the front of the eyeball, letting light in and playing an important role in focussing light rays onto the retina.	Cornea	72%
The white, outer layer of the eye; tough and strong so little damage can be done to the eyeball.	Sclera	66%
Attached to suspensory ligaments and control the position of the lens so it can focus the light by contracting/relaxing.	Ciliary Muscle	62%
Sit either side of the lens and hold it in position.	Suspensory Ligaments	57%
