Overview

What is dry eye disease?
Dry eye is a chronic and uncomfortable condition. In this condition, the eyes are not able to produce an adequate quantity of tears or the quality of tears are poor.
Types of dry eye disease
Dry eye disease can be of two types. It is very rare for a patient to suffer from both types of disease at the same time.
Meibomian glands are present in the eyelids, which produce lipid or oily part of the tears. Inflammation in the meibomian gland causes inadequate production of meibum. In the absence of lipid, the tear film breaks down due to evaporation of the underlying aqueous layer.
Insufficient production of the watery part of tears by lacrimal glands can cause aqueous tear-deficient dry eye.
Hence dry eye can occur due to inadequate production of tears or adequate production but higher evaporation of the tear film.
Symptoms of dry eyes
Dry eye occurs when the tear film is not healthy. As result, your eyes become irritated. In response to irritation, the eyes produce excessive tears. This is called reflex tearing. Your eyes may produce tears as a response to the ocular irritation, but these tears are of poor quality and they do not lubricate the ocular surface. Hence dry eye can also present as watering.
