|
Cornea: |
the clear
front window of the eye. The cornea transmits and focuses light
into the eye. |
|
Iris: |
the colored
part of the eye. The iris helps regulate the amount of light that
enters the eye. |
|
Lens: |
the
transparent structure inside the eye that focuses light rays onto
the retina. |
|
Macula: |
a small area
in the retina that contains special light-sensitive cells. The
macula allows us to see fine details clearly. |
|
Optic Nerve: |
the nerve that
connects the eye to the brain. The optic nerve carries the
impulses formed by the retina to the brain, which interprets them
as images. |
|
Pupil: |
the dark
center in the middle of the iris. The pupil determines how much
light is let into the eye. It changes sizes to accommodate for the
amount of light that is available. |
|
Retina: |
the nerve
layer that lines the back of the eye. The retina senses light and
creates impulses that are sent through the optic nerve to the
brain. |
|
Vitreous: |
the clear,
jelly-like substance that fills the middle of the eye. |
