CORNEA CENTER
The cornea is the clear, dome-shaped surface that covers the front of the eye. The cornea has two primary functions:
There are two focusing areas of the eye, the cornea and the lens. When light strikes the cornea, it bends, or refracts, the incoming light onto the lens. The lens further refocuses that light onto the retina, a layer of light sensing cells lining the back of the eye. The retina converts the light rays into impulses that are sent through the optic nerve to the brain, which interprets them as images. The refractive process is similar to the way a camera takes a picture. The cornea and lens in the eye act as the camera lens. The retina is similar to the film. If the image is not focused properly, the film (or retina) receives a blurry image.
It is important to keep the cornea healthy for clear vision. Common corneal problems include:
The cornea is the clear, dome-shaped surface that covers the front of the eye. The cornea has two primary functions:
- to shield the inside of the eye from germs, dust and other harmful matter. The cornea shares this protective task with the eyelids, the eye socket, tears and sclera (white part of the eye).
- to acts as the eye's outermost lens. The cornea functions like a window that controls and focuses the entry of light into the eye.
