What is dry eye?

In a normal eye there is a tear film in front of the cornea that lubricates, nourishes, and protects the eye from dust and other irritants. Spread by blinking (one every 5-6 seconds), it keep the surface of the eye optically clear and smooth, and also protect from infection.  This film has several layers of fluid viz. the lipid, or oil layer; the watery layer; and mucus layer and is not like ordinary water in its composition. All three layers of tears are necessary for proper lubrication. Persons with CVS have tears that are mostly water and evaporate quickly, providing little protection for the eye. This can result in dry, irritated and uncomfortable eyes. This excess production of water from the lachrymal gland in dry eyes results in watery eyes. Other symptoms of dry eye may include eye strain, headache, blurred vision, itchy eyes, red or burning eyes.
