Dry eye is state wherein the tear produced in the eye cannot nourish and lubricate the cornea and conjuntiva of the eye(Frontal portion of the eyeball). This cause cornea and conjunctiva to become inflammed. Tear is important as the cornea of the human eye is avascular (Contains no blood vessels). Dry eye is a chronic condition. Tear film in firmly distributed on the frontal surface with each blink of the eyelids. Tear may look like normal water but it contains multiple vitamins and minerals that helps to feed the cornea and protect the eye with its antibiotics features. Too less or Too high secretion of the tear, both can be a problem.
The tear is secreted by multiple glands on the eyelids and conjunctiva.Tear is consists of 3 different layers. Aquous(Contains water), Mucin(Contains Mucous), Lipid( Contains Oil). The watery layer can get evaporated quickly due to wind or hot climate. This is the leading cause of dryness felt by patients. The lipid layer is secreted by meibomian glands of the eyelid margin. The lipid layer protects the evaporation of the watery layer. Those people having inadequate watery layer are told to be having dry eye syndrome also called as KCS (kerato conjunctivities sicca).
