4. How Our Eyes Work… • Iris- is the colorful part of the eye • Pupil- pupil is the black circle in the center of the iris, which is really an opening in the iris, and it lets light enter the eye. • Cornea- helps the eye focus as light makes its way through. • Retina- takes the light the eye receives and changes it into nerve signals so the brain can understand what the eye is seeing. • Sclera- is made of a tough material and has the important job of covering most of the eyeball. • Optic Nerve- is a messenger to the brain
