Eye Parts

muscle that opens and closes the pupil; the colored part of the eye

• iris

• pupil

• cornea

• fovea

protects the eye and bends light to provide focus

• cornea

• fovea

• iris

• retina

opens and closes to adjust how much light come in (like the shutter of a camera)

• iris

• pupil

• optic nerve

• fovea

behind the pupil, constantly changes depending on whether we are looking at objects closer or farther away

• lens

• pupil

• iris

• optic nerve

The bending of the lens to focus objects

• transduction

• foveal vision

• peripheral vision

• accommodation

at the back of the eye; made up of many cell layers, light passes through these layers in order for transduction to occur

• retina

• fovea

• lens

• iris

first layer of the retina

• epithelial cells

• rods and cones

• optic nerve

• transduction

are more abundant and are spread throughout the outside of the retina; enable black and white vision

• cones

• rods

• optic nerves

• corneas

focused on the center of the retina; enable color vision

• rods

• cones

• optic nerves

• corneas

the center of the retina where images are focused by the lens

• pupil

• cornea

• lens

• fovea
