If you have dry eye, your symptoms may include irritated, scratchy, dry, uncomfortable or red eyes, a burning sensation, excessive tearing, blurred vision, or a feeling of something foreign in your eyes. Excessive dry eyes may damage eye tissue, scar your cornea (the front covering of your eyes) and impair vision and make contact lens wear difficult.
The tears your eyes produce are necessary for overall eye health and clear vision. Dry eye means that your eyes do not produce enough tears or that you produce tears that do not have the proper chemical composition, (there are three different components to tears). Dry eye is more common as we age. It can also be caused by blinking or eyelid problems, or some medications or a dry climate.
Dry eyes are caused by a lack of adequate tears or some parts of the tear not being produced. Your tears are a complex mixture of water, fatty oils and mucus. This mixture helps make the surface of your eyes smooth and clear, and it helps protect your eyes from infection. For some people, the cause of dry eyes is decreased tear production. For others it’s increased tear evaporation and in others an imbalance in the makeup of your tears.
It is important that the Ophthalmologist conducts various tests to find the underlying cause of the dry eye and then the correct treatment plan can be implemented. If the cause of the dry eye problem is not fully diagnosed, and the correct treatment is not organized by an Ophthalmologist it can lead to various complications:
