Eyes

The eye is the organ of sight. Light rays enter the eye through the pupil (the circular opening in the center of the iris). The cornea (the tough, transparent, dome-shaped covering of the front of the eyeball) and the lens (the transparent, internal optical component of the eye) focus the light rays on the retina (the lightsensitive membrane that lines the back of the eye) to form an image. The image is converted to electrical impulses that move along the optic nerves to the visual cortex (the area of the brain that is concerned with vision), where the image is perceived.

Although many vision problems are minor and may be easy to treat, others may cause serious complications that, if left untreated, can lead to vision loss or even blindness. Most vision problems are detected during a routine eye examination. That is why it is important for you to have regular eye examinations, especially as you get older.
