Dry eye syndrome (DES), also known as keratoconjunctivitis sicca (KCS), is the condition of having dry eyes. Other associated symptoms include irritation, redness, discharge, and easily fatigued eyes. Blurred vision may also occur. The symptoms can range from mild and occasional to severe and continuous.
Dry eyes can be caused by medication, dehydration, inflammation of the eyelids and/or skin, previous eye surgery, systemic diseases such as rheumatoid arthritis, thyroid disease, lupus, sarcoidosis and even poor blinking habits (such as staring at a computer). Tears are not just water.
