Retina

Back 30

The light-sensitive inner surface of the eye.

containing rods and cones + layer of neurons that begin the processing of visual information

Front 31

Accommodation

Back 31

The process by which the eye's lens changes shape to focus near or far objects on the retina

Necessary for peripheral and Twilight Vision when Cons don't respond

Front 33

Cones

Back 33

Retinal receptor cells near the center of the retina

functions in daylight or well the conditions

detect fine detail and color Sensations

Front 34

Optic nerve

Back 34

The nerve that carries neural impulses from the eye to the brain

Front 35

Blind spot

Back 35

The point at which the optic nerve leaves the eye creating a " blind spot" because no receptor cells are located there

Front 36

Fovea
