Pupil: the openning in the eye that lets light into the eye

Lens:focuses light on the retina using process of accomodation (becomes flat=farther away or round=up close)

Retina: neural tissue that absorbs light and convert it into a neural message (consolidate light energy)

Optic Disk: a hole in the eye that allows ganglion cells to travel to the brain

Optic Nerve: bundle of ganglion axons that take neural message to the brain
