An eye disorder known as Dry eye is caused when the eyes are not capable of producing sufficient levels of tears. Sometimes, it is also observed that the tears dry up very quickly or just evaporate. This defect occurs due to a blockage found in the oil glands or it could also be a result of the possible abnormality found in the glands.
Lack of required lubrication as well as moisture content for the eye surface region causes this disorder. Sustained irritation is caused due to inflammation caused in the front tissues known as anterior of the eyes. This results in redness of the eyes and also causes the eyes to swell. A constant feeling of irritation can be sensed. In medical terms, this disorder is known as keratoconjunctivitis sicca which means dryness of the eyes.
There are multiple causes responsible for the disorder of Dry eye. There are several factors ranging from weather to medically diagnosed reasons causing this disorder.
This disorder can be caused specifically under bad weather conditions or sudden change in the weather such as dry and hot climate or an extremely windy weather. Some medicines are associated with a lot of side effects. Dry eye can be a potential result of a side effect caused by intake of certain medication. Changes occurring in the body hormones can cause this disorder to take place. The ageing factor can also be responsible for causing of such disorder. The human eye produces tears through a proper channelized system known as lacrimal functional unit. This unit is responsible for generating tears as and when required to give lubrication to the eyes. There are several parts included in this particular unit. If in case, any of the parts in this unit do not function properly, disorders such as dry eye can be caused. The two possible impacts that can be caused are bifurcated on the basis of the quantity of tears and the quality of tears. Either the tears are not produced in sufficient quantities causing the eyes to dry out or the quality of the tears may become inferior due to certain abnormal proteins present in it thus causing harm to the surface of the eye.
