What Causes Dry Eyes

In order to function properly, the eye depends on the flow of tears to provide constant humidity and a lubricant to keep the vision and comfort. Tears are a combination of water, such as a humidifier agent, Oil, lubricating agent, Mucus, to flatten the propagation; and specific proteins and antibodies, such as resistance to infection. All these components are released from the special glands around the eyes.

But this urgency, tears are made only of water and do not have the quality or composition of the normal tears of lubricant. These false tears can rinse the dirt, but will not cover the eyes well.
