The eyes are your window to the world. Not only do your eyes tell a tale during your times of happiness, but also in your times of sadness. You may cry out of joy or in pain, the only thing common to the two situations is the secretion of tears. They help provide lubrication and moisture which help you see properly and ensure that your eyes are comfortable. Tears are a mixture of several substances which include water for moisture, oils for lubrication, mucus to ensure that they spread evenly and antibodies and special proteins which ensure that infections are kept at bay.

Symptoms and causes of dry eyes
There are several symptoms of dry eyes which include itching, redness, blurry vision, light sensitivity, a gritty feeling, and a feeling like there is something in your eye when there is actually nothing. The condition may sometimes lead to the secretion of excess tears as well. This condition is referred to as reflex tearing. This occurs as there is a lack of moisture in the eye that causes irritation.
