What is dry eye syndrome and what are the reasons of the disease?

Dry eye syndrome is the loss of the eye’s ability to produce a natural tear. This is one of the most common reasons for visiting an ophthalmologist. Many factors can cause or contribute to this problem. Some of them are associated with age, some with environmental impact. This is a common and treatable condition.

Dry eye syndrome can occur due to a number of reasons, both physical and due to the impact of environmental factors. One common cause is the slowing of the formation of tears. This occurs naturally with aging, especially in women during menopause.

What does cause dry eye syndrome?

The quality of tears can also be a cause of dry eye syndrome. Normally, the tear consists of three components (water, mucin, and fat). The effect of these three components is interrelated, and thus a sufficient amount of moisture is provided. It is distributed evenly over the cornea and evaporation is prevented, which can contribute to dry eyes. If any of these three components are disturbed, the eye may not receive the nutrition and protection that it needs. Most often, a tear contains an insufficient amount of fat. This leads to evaporation and causes dry eye syndrome.

Reducing the formation of tears can be associated with the use of certain medications (antihistamines, birth control pills, diuretics, cardiovascular drugs, analgesics and anti-inflammatory drugs). It can also be associated with certain diseases, such as diabetes, rheumatoid arthritis or thyroid problems.
