 Iris- irido- a muscle that allows light rays in
and it determines the color of the eye
 Pupil- a hole
 Lens-located behind the iris, helps light focus
onto the retina

lens to change shape
 Vitreous humor-transparent mass of gel that
lies behind the lens and in front of the retina.
It fills the center of the eye
 Optic nerve- nerve in the back of the eye that
carries visual images to the brain
 Optic disc- blind spot- the area where the
