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.
When your eyes are optimally functioning, a thin film coats your eyes, called a tear film. The tear film is made up of mucus, an acquaeous layer of salt-like solution, and lipids. Dry eye syndrome is a disorder of the tear film, causing fewer tears and/or a lower quality of the tears produced. Dr McDonald warns that though dry eye syndrome is common (and incurable), if left untreated, it can cause damage to the eye.
