transfer of visual information

Cornea

to allow light through

Lens

focusing the arriving image

Black/ delivers oxygen and nutrient to retina

Retina

receive light from lens

Optic Disk

places where axon exits

Vitreous Humor

helps maintain eye shape

Pupil Function

light into eye

Iris Function

controls the size of pupil

Choroid

Sclera

Tough, white outer coat of the eyeball
