exit point of the optic nerve cutting through the retina so no rods or cones Blind Spot Optic Nerve carries the impulses from the rods and cones to the visual center of the brain. Fovea a tiny area of densely packed cones for detailed and coloured vision. Cornea bends incoming light focusing it on the retina. Lens accommodation & focusing of light onto the retina. Pupil a hole in the iris that lets light into the back of the eye. Iris controls the pupil size thus controls entry of light.

Ciliary Body a ring of muscle controlling the shape and curvature of the lens. Retina contains rods and cones which convert light into nerve impulses. Sclera Choroid prevents internal reflection of light and nourish retina. Structure Function(s) tough outer layer of the eye which overs and protect eyeball.
