Lack of tears leads to drying of eyes which causes irritation and itching. This condition affects almost 25-30 million people in the United States. In case you are one of those suffering from this condition, read on to know about dry eye medication and treatment...
The tears that roll down the cheeks as a result of joy or sorrow that we feel, do more than just play a mirror to our emotions. Tears form a thin film over our eyes. It lubricates the eyes, giving a clear vision. Tears are produced by lachrymal glands in our eyes. When tears are not produced in enough amount or when they are evaporated from our eyes, it leads to dry eye syndrome (DES). Though this is one of the most common eye problems in older people (those over 40 years), excessive exposure to computer or watching too much television causes DES in younger people as well.
