Tears provide moistures and keep the eyes lubricated. Generally, tears contain water, oil, mucus and special proteins which protect from eye infections. In contrast dried eyes mean the eyes are deprived of the essential tears. Dry eyes don’t have adequate moisture. Those who suffer from dry eyes experience different symptoms such as itching, redness, and blurred vision.
The eyes of people with dry eye syndrome fail to maintain a normal layer of tears which coat the eyes. It prevents the keeping away of the eye irritants.
In some cases dry eyes also result in excess tears which are known as reflex tearing. Low moisture content causes irritation in the eye and asks the nervous system for more lubrication. In response to tears are generated to make up for the dryness in eyes. Tears keep the eyes protected and wash the dust and grime from the eye.
