Tears normally bathe the eye and wash out any dust or debris from the eye. Thus they helps in keeping the eye moist. Tears also contains enzymes which helps in neutralization of the microorganisms which generally lives in the eyes. Hence, we can say that the tears are very important for good eye health.

In case of dry eyes, the person’s eye does not produce enough tears. Moreover, the tears also have such a chemical composition due to which they evaporate very quickly. Dry eyes may occur as a part of natural aging process, especially during menopause. It may also occur as a side effect of certain medications such as antihistamines, antidepressants, certain blood pressure medicines, and birth control ills, etc.

Dry Eyes are also a symptom of systemic disease such as Rosacea or Sjogren’s syndrome long term contact lens wear is another cause for dry eyes. In this case, the contact lenses are felt to be uncomfortable and thus the rubbing of the conjunctiva may cause dry eyes. Dry eyes are commonly seen in women, basically due to hormone fluctuations. Smoking also increases the risk of dry eyes.

Signs and symptoms of dry eyes

There may be persistent dryness, scratching and burning sensation in the eyes. In order to measure the amount of tears in the eyes, a thin strip of filter paper is placed at the edge of the eye and it is called a Schirmer test.

Few people may also experience a foreign body sensation. It is a feeling that there is something in the eye. Although, it may seen odd but sometimes watery eyes can result from dry eyes.
