The eye is made up of so many parts. Like a camera, what we see from the outside is only a simple picture to what lies beneath. The overall function and design of the eye is much more than just a white ping-pong sized ball with a colorful space and a little black dot. Your eye is the window to the world. It takes thousands of 'calculations' so to speak. What you see is only a small part of the overall picture. The following is a summary of each part and its function.
* Eye socket: This is the hollow space, the opening in the head. This space holds and Supports the function of the eyeball itself
* Eyelid: The skin over the eyeball. This skin moves through muscular automatic and voluntarily movements. It acts in this capacity to help keep the eyeball moist and to keep it clean and free from debris.
* Eyelashes: These are the tiny hairs framing at the end of the eyelid.The lashes although decorative are there for much more than holding mascara. Lashes work to catch dirt and minimized it's entrance to the eyeball.
* Eyeball: It is the ping-pong sized white part of the eye. The white part of the eye is made up of a tough material called sclera. It covers a huge part of the outer covering for the eye. The eye has noticeable tiny pink threads, (Blood Vessels) which deliver blood to the sclera.
* Cornea Clear/Transparent dome: This dome sits in front of the colored part of the eye. It help the eye focus as light passes through.
* The Iris: The colored part controls how much light goes through the pupil
* The Pupil: The Little Black Dot set in the center of the eye, the pupil is actually an opening into the inner parts, the size of this black dot is dependent on the amount of lights it's exposed to. When the dot is smaller, it's due to brighter light, thereby minimizing the amount of light that enters. When it's larger, this is due to a darker area, in opening, it allows more light in, so you can see a little better in the dark.
* Anterior Chamber(not visible: The space between the cornea and the iris. The transparent fluid is there to nourish they eye.
* Retina(not visible: Processes what the eye sees. It receives the signals or information which is sent to the brain for understanding.
Your retina is at the far back part of the eye that takes the light the eye receives and changes it into nerve signals so the brain can understand what the eye is seeing. It uses cells called rods and cones to process light. In all there are about 120 million rods and 7 million cones per eye.
* Lens (not visible: Like a camera, the lens processes and captures the image. It is held by fibers which are attached to muscles called ciliary muscles. It actually changes the size and shape of the lens.
* Vitreous (not visible: This sits behind the lens, and forms two thirds of the eye's volume and gives the eye its shape. It's filled with a clear, jelly-like material called the vitreous humor.
* Rods (not visible: Works the processing of black, white, and shades of gray.
* Cones(not visible: Work to process color. They only see colors. They are most sensitive to one of three colors; red, green, or blue. Together they are able to differ what they see to form millions of other colors. Those without functioning cones experience color blindness.
* Optic Nerve:(not visible: Acts as the messenger in the back part of your eye. It carries the information it sees to the brain for understanding.
* Lachrymal Glands Tears: These glands produce tears for flushing foreign bodies from the eyes. This fluid is regulated by blinking.
Your eyes do so much; protect them and SEE how great they really are!!
