Tears are essential for our eye to stay healthy. A film of tear spreads evenly over the eyeballs everytime we blink our eyes. The tears help in maintaining the smooth and clear surface of the eye. For having a good vision, the film of tear is essential. Sometimes our eyes fail to make enough tears or one or more layer of the tear film is affected which leads to the condition called dry eyes. Here is everything you need to know about this disorder.
What is dry eye syndrome?
Dry eye syndrome is also called Keratoconjunctivitis Sicca. It is a common defect of the eye where the eyes are not lubricated adequately due to the lack of tear production. There is chronic lack of moisture and sufficient lubrication on the surface of the eye. It results in subtle yet constant irritation of the eye along with inflammation. It could eventually lead to scarring of the eye.
Dry eye is usually felt in certain conditions like in an air-conditioned room, on an airplane, when you’re gazing at a screen for long or while riding bikes. This condition usually affects people over the age of 40 years and is mostly seen in women than men. The term ocular surface disease and dysfunctional tear syndrome is also used for the defect.

Causes of dry eye syndrome
Our tears are a mixture of water, fatty oils, and mucus. This mixture is essential for keeping the surface of the eyes smooth and moist and preventing infection.

- Medical conditions like diabetes, vitamin A deficiency, rheumatoid arthritis, lupus, scleroderma, thyroid disorders and Sjogren’s syndrome.
- Some drugs or medications like antidepressants, antihistamines, hormone replacement therapy, decongestants and drugs for birth control, high blood pressure, Parkinson’s disease and acne.
- It can also be a side effect of laser eye surgery.
- Damage to the tear gland due to radiation or inflammation.

- Problems in the eyelids like turning out or in of the eyelids.
- The imbalanced composition of tears: If any of the three components of the tears, oil, water or fatty acids are not secreted in the right amount it could lead to the condition called dry eye syndrome.
