Dry eye syndrome can occur at any age, and in people who are otherwise healthy. It is more common with older age, when the individual produces fewer tears. It is also more common in women than in men.
Causes of Dry eye syndrome
It is more common in places where malnutrition results in a vitamin A deficiency.
The eyes produce tears all the time, not only when we yawn or experience emotion. Healthy eyes are constantly covered with a fluid, known as a tear film. It is designed to remain stable between each blink. This prevents the eyes from becoming dry and enables clear vision.
If the tear glands produce fewer tears, the tear film can become unstable. It can break down quickly, creating dry spots on the surface of the eyes.
The tear film has three layers, oil, water, and mucus. Problems with any of these can lead to dry eye symptoms.
Using a computer monitor, reading, or driving a vehicle, as the increased visual concentration may slow down the blinking rate, so that the eyes become dry.
Treatment for Dry eye syndrome
Consult your nearest ophthalmologist before applying artificial tear drops and ointments. Drops are the most common treatment. Many types of drops are available over pharmacy
