Dry Eye syndrome

Dry eye occurs when the eye does not produce tears properly, or when the tears evaporate too quickly.

If left untreated, this condition can lead to pain, ulcers, or scars on the cornea, and some loss of vision. But, permanent loss of vision from dry eye syndrome is uncommon.

What is dry eye syndrome and how to avoid it?

Types of dry eye syndrome:-

1) the lacrimal glands fail to produce enough of tears to maintain a healthy eye surface.
2) Evaporative dry eye result from inflammation of the meibomian glands, located in the eyelids. These glands make the lipid or oily part of tears that slows evaporation and keeps the tears stable.

Dry eye can be associated with:-
• inflammation of the surface of the eye, the lacrimal gland, or the conjunctiva;
• an increase in the surface of the eye, as in thyroid disease when the eye protrudes forward.


Tears,produced in the lacrimal gland, are necessary for overall eye health and clear vision. Tears bathe the surface of the eye, keeping it moist, and wash away dust and debris. They also help protect the eye from any types of infections.

When the lacrimal glands fail to produce sufficient tears, dry eye can result.Any disease process that alters the components of tears can make them unhealthy and result in dry eye.
