Document Summary

Cornea: the covering, protects the eye, helps focus light, not able to move itself. Pupil: allows light in, adjusts to let in more/less light in -- think about it like a camera! Iris: connected to muscles that help the eye constrict and dilate. Lens: focuses light for near/far objects, can adjust its size. Fovea: center of visual attention/detail, helps concentrate on where you are focusing your vision. Optic nerve: pathway from the eye to the brain -- wires into occipital lobe. Occipital lobe: part of the brain where visual information is sent to be processed. We take information in through both eyes which is important to 3d depth perception . We see in three colors - the presence or absence of them. We have three trichromatic cones - discern between blue/yellow, green/red, and light/dark. The dual process theory : opponent process cells interpret color and light/dark, our eyes see and our brains process the visual information from our eyes.
