Eyes are an incredible part of the human body. They quickly react to the
things happening around us, perceiving objects we might not realize are there.
Eyes are full of nerves that help communicate to the brain what action should be taken. Read on
to learn about the different functions and important components of an eyeball.
Parts of the Eye
The main parts of the eye consist of the cornea, iris,
crystalline lens, retina and pupil. Together these structures help to filter light in various ways and ultimately
allow us to see objects clearly. The cornea and iris act as light filters,
allowing various levels of light to hit the back of the eye through the
dilation of the pupil. From there, the light hits the crystalline lens
as a last stop before reaching the retina. Signals are then sent to the
brain and we are able to better understand our surroundings.
Holding It All Together
Our eye helps us see, but have you ever wondered how your eye stays in
place or even moves? These functions are possible with the help of different
ligaments and muscles in, on and around the eye. The suspensory ligament
zonules are responsible for holding part of the eye together. There are
two different rectus muscles that help move the eye up and down. Finally,
the optic nerve that helps transmit information to the brain and also
helps anchor the eye in its socket.
Beyond Eyes for Sight
Eyes are obviously well-built for seeing but there are other parts of the
body that make sight possible! Eyelids produce tears to keep our eyes
well lubricated and nourished. They also protect the eyes when it is too
bright or they are in a potentially dangerous situation. Muscles behind
the eyes help to control the movement and thus our ability to see things
within a wide range.
