Eye Anatomy: What's Inside the Eye?

The eyes are wonderful enough and they work like a camera. They
can take pictures of the world and sends them to the brain. The brain
works out what the eyes see. This happens the moment you open
your eyes in the morning and when you close them at night. The eyes
work in a similar way with a camera. The light passes through the lens
and is being recorded on the back of the eye or the retina.

Cornea - A see-through skin that
covers the front of the eyes. This is
clear like a glass and has no blood
vessels.
Sclera - A tough skin that covers the
outside part of the eyeball. This is also called as the
white of the eye.
Iris - This controls the amount of light entering the eye.
This is also the colored part of the eye.
Pupil - This is the hole in the colored part (iris). It lets
light enter into the eye. It becomes very small in bright
lights, and bigger in dull lights.
The Lens - This focuses the light to the retina. Its shape
changes in order to make sure that the picture on the
retina is clear.

Retina - This is like a movie screen that shows the
picture you see. This has two lots of cells known as rods
and cones. The rods see black and white. Cones see
colors. These two turn the picture into an electrical
message to the brain.
Blind Spot - This a bit of the retina, which is not
sensitive to light because it has no rods and cones. This
is the spot where the optic nerve is joined to the
retina.
Optic Nerve - This is where the messages from the
retina travel going to the brain. It is like a cable that
carries the TV pictures from aerial to the TV so you can
see the programs.
Eyelids and Eyelashes - They protect the eyes. The
eyelids shut out light so a person can sleep. They will
also shut off fast when they feel that something is
trying to get into the eye. Eyelashes on the other hand,
are very sensitive, and when they feel that dust is
coming, they trap it as the eyelid closes.

Eyebrows - They help keep sweat and dust out of the
eyes
Tear Glands - These are small glands inside the upper
eyelid. They produce tears to keep the surface of the
eyeball moist and clean and protect it from damage.
When you blink, the eyelids spread the tears over the
surface of the eye.
Conjunctiva - A thin lining inside the eyelid and the
outside of the front of the eye. It has some tiny blood
vessels over the eye. When the eyes get sore, the
blood vessels become bigger and the eyes look red.
Ciliary Muscles - These are circles of tiny muscles
around the lens. They change the shape of the lens by
relaxing and squeezing. Relaxing means making the
lens thinner for far away objects, while squeezing is
making the lens fat to look at nearby objects.
Eyes are amazing and it is our responsibility to look after
them carefully. We can undergo eye examinations and
wear protective accessories to ensure the health and
protection of our eyes. Keeping ourselves informed
