The cornea is the eye’s outermost layer. It is the transparent, dome-shaped surface that covers the front of the eye. The main function of the cornea is to allow light to pass into the eye, so that it can reach the lens and the retina. A second chief function of the cornea is to help focus light, much like a camera lens.
The cornea is a small but very complex structure that acts against germs, dirt, and other foreign particles. It is a highly organized tissue and unlike most bodily tissues, it lacks blood vessels to nourish and protect it from infection. Instead, the cornea gets its nutrients from tears and the aqueous humor. Corneal health depends on a number of factors, including the health of the conjunctiva and of the eyelids. The conjunctiva is thetissue which covers the front part of the eye (but not the cornea) and lines the back of the eyelids. Both the conjunctiva and the eyelid contain glands that create the tear film, which is essential to the maintenance and overall health of the cornea.
The cornea has the ability to typically heal small injuries or scratches on its own, however major injuries to the cornea can result in progressive problems that can have a large effect on our vision and overall health of the eye. Diseases and conditions affecting the cornea can cause distorted vision or vision loss.
If you are experiencing any of the symptoms below, there may be more damage to the cornea than you think and it is important to get them examined by a trained professional.
