A dry eye is a common condition when tears are insufficient in lubrication for the eyes. According to the American Academy of Ophthalmology (AAO), an estimated 16 million people in the country are affected by dry eye disease yearly. If left untreated, chronic dry eye can cause damage to the surface of the eye and impair vision, and significantly affect a person’s quality of life. This article discusses everything one needs to know about the condition.

Causes of dry eyes
Dry eyes can be caused by various factors, including aging, hormonal changes, certain medications, medical conditions such as Sjogren’s syndrome, environmental factors such as dry air or wind, and prolonged screen time. It is not a seasonal condition, nor is it contagious.

Symptoms of dry eye
The signs and symptoms of dry eyes include:
Burning, stinging, or itching sensation in the eyes
Sensitivity to light
Blurred vision
Redness of the eyes
Watery eyes which is the body’s response to dryness
Mucus in or around the eyes

Treatment for dry eye
There are several treatments available for dry eyes. Some of them include:

Punctal plugs
These tiny plugs are known to be positioned into the tear ducts to block the drainage of tears from the eyes, helping to keep them moist.

Meibomian gland expression
This is a procedure in which a doctor massages the Meibomian glands in the eyelids to help release the oils that help to lubricate the eyes.

Intense pulsed light therapy
This newer treatment uses light to help reduce inflammation in the Meibomian glands and improve the quality of the tears.

It is essential to consult an eye doctor to acquire the best treatment approach for a specific case of dry eyes.
