“Dry eye” is a common condition nowadays. This condition occurs when your tears can't provide adequate lubrication for your eyes. Tears can be inadequate for many reasons: you don't produce enough tears or if you produce poor-quality tears.

An adequate layer of tears on the surface of the eye is essential to keep your eyes healthy, comfortable and seeing well. The tear film bathes the eye's surface to keep it wet and wash away dust, debris and microorganisms that could damage the cornea and lead to an eye infection.

Dry eye disease is caused by a lack of adequate tears. Your tears are not made just by water: they are made by a complex mix of water, oils and mucus. These components help make the surface of your eyes smooth and clear and help protect your eyes from infection.

Symptoms of dry eye may differ from one person to another. Some are very easy to detect and to relate to dry eye and other may be quite odd. But all of them should be considered and not ignored.

There are different categories of dry eye disease depending on which tear film layer is affected. The specific type of dry eye disease must be determined to address the patient to the right type of treatment.

Dry eyes disease is not only providing discomfort. People who experience this condition may also lead to severe complications.
