A Critical review on Dry Eye Syndrome and its Ayurvedic Approach
To help keep your eyes comfortable and your vision optimal, a normal, thin film of tears coats your eyes. Three main layers make up this tear film:
The innermost layer is th e thinnest . It is a layer of mucin (or mucus ) layer of mucus is produced by the cells in the conjunctiva (The mucus helps the overlying watery layer to spread evenly over the eye . The middle (or aqueous) layer is the largest and the thickest . This layer is essentially a very dilute saltwater solution. The lacrimal glands under the upper lids and the accessory tear glands produce this watery layer. This layer's function is to keep the eye moist and comfortable, as well as to help flush out any dust , debris, or foreign objects that may get into the eye. The most superficial layer is a very thin layer of lipids (fats or oils). These lipids are produced by the Meibomian glands and the glands of Zeis (oil glands in the eyelids). The main function of this lipid layer is to help decrease evaporation of the watery layer beneath it. Dry eye syndrome (DES) is a common disorder of the tear film , affecting a significant percentage of the population , especially those older than 40 years of age. DES can affect any race and is more common in women than in men. Dry Eye Syndrome is more prevalent in Metro-cities. Research shows that cities with high levels of air pollution have an increased risk of dry eye syndrome.
Dry Eye Syndrome is high among computer users. More that 75% of people, who routinely use a computer at work may suffer from dry eye syndrome. The symptoms of dry eye i.e. dryness, irritation, foreign body sensation, redness etc. are similar to that of Shushkakshipak. Thus Shushkakshipak can be correlated with dry eye syndrome
