Do you find yourself rubbing your eyes often because they feel irritated? This is a common symptom of dry eyes.
Your eyes contain tear ducts that produce tears. These tears act as lubrication, wetting your eye and keeping them healthy in the process. But sometimes, your tear ducts fail to produce the tears needed to protect your eyes. Or, the tears produced evaporate quicker than usual, resulting in your eyes feeling un-lubricated and dry. This is what creates the sensation of irritation that makes you want to rub your eyes.
