The term "corneal disease" refers to a variety of conditions that affect mainly the cornea. These include infections, degenerations, and many other disorders of the cornea that may arise mostly as a result of heredity.
The cornea plays a key role in vision. As light enters the eye, it is refracted, or bent, by the outside shape of the cornea. The curvature of this outer layer helps determine how well your eye can focus on objects close-up and far away. The cornea is the clear, protective outer layer of the eye. Along with the sclera (white of the eye), it serves as a barrier against dirt, germs, and other particles that can harm the eye's delicate components. The cornea is also capable of filtering out some amounts of the sun's ultraviolet light but not enough to replace the need for wearing sunglasses outdoors.
Diseases or injuries of the cornea can affect your vision in many ways. If a cornea is “scratched“ it can usually repair itself very quickly, however if there is scarring or deeper abrasions they can cause the cornea to lose transparency which may lead to visual difficulty. Keeping the cornea healthy is a vital part in protecting your vision and the health of the eye. The cornea also serves as a filter, screening out some of the most damaging ultraviolet (UV) wavelengths in sunlight. Without this protection, the lens and the retina would be highly susceptible to injury from UV radiation.
