The eyes are fairly complicated organs that work with the brain and perform the same function as a camera in that they convert light waves into a medium that can be understood by another mechanism. In the case of the eye light waves reflected off of an object or projected from a light source pass through the cornea which is the outer lens and then enters through the pupil. The pupil regulates the amount of light that comes through the lens in order to prevent the cells of the retina from being overloaded. As the light waves pass through the lens their path is altered in such a manner that they are focused into a viable image on the retina which then converts the information into electrical signals that are interpretable by the brain. These signals travel to the brain via the optic nerve and then are translated into understandable information and then utilized and possibly stored for future use.http://www.99main.com/~charlief/Blindness.htm

The eye itself is made up of many parts that allow it to function in a manner that allows us to see. The sclera is the outer coating which protects the inner workings of the eye and allows for the attachment of the muscles which allow us to move the eye within the socket. The eyelid and the eyelashes are used to protect the front of the eye from debris and other possible sources of harm. The Cornea begins the focusing process which is continued by the pupil being contracted or dilated by the muscles in the iris and further refined by the lens behind the pupil. Once the image has been processed by the focusing system it travels along the visual axis and strikes the retina, the macula, and the fovea where it is converted into electrical impulses and transmitted via the optic nerve to the brain. http://www.99main.com/~charlief/Blindness.htm

1. Cornea: Clear outer layer of the eye
2. Pupil and iris: Control the amount of light that enters the eye
3. Lens: Focuses the light on the retina
4. Vitreous Gel: Fills the inside of the eye
5. Sclera: White part of the eye
6. Retina: Converts light to electrical impulses
7. Optic nerve: Transmits electrical impulses to the brainEye care: Eye Anatomy

Several factors impact the health of the eyes such as a diet, smoking and ultraviolet rays.Life Extension Foundation: Healthy Eyes

Some problems that involve the eyes are: pinkeye, dry eye, cataracts, macular degeneration, glaucoma, eye cancer and retinoblastoma.Merck Manuals: Eye Disorders Merck Manuals: Retinoblastoma Medlineplus: Eye Cancer
