Dry Eyes

Dry eye disease is a common condition that occurs when your tears are unable to provide enough water for your eyes. Tears may be insufficient and unstable for several reasons. For example, dry eyes may occur if the tears your eyes produce are insufficient or of poor quality. The instability of tears leads to inflammation and damage to the surface of the eye



Signs and symptoms that commonly affect the eye may include:

Stinging, burning, or roughness in the eye

Sticky pus in or around the eyes


Eye redness

The feeling of having something in the eyes

Difficulty wearing contact lenses

Difficulty driving at night with tears in the eyes, and the body’s response to irritation of dry eyes

Blurred vision and eye fatigue


The reasons

There are various causes of dry eyes that impair the normal functioning of the lacrimal membrane. The lacrimal membrane consists of three layers: the outer fatty layer, the middle aqueous layer, and the inner mucous layer. Thanks to this composition, the surface of the eye remains moist, smooth, and clear. Problems with any of these layers cause dry eyes.


There are many causes of lacrimal membrane dysfunction, including hormonal changes, autoimmune diseases, blepharitis, and allergic eye diseases. In some cases, dry eyes are caused by decreased tear production or increased tear evaporation.



People with dry eyes face the following complications:

Eye infection; Tears protect the surface of the eye from infection. The risk of developing an eye infection may be increased if the eye does not produce enough tears.

Ocular surface damage. Severe dry eyes can lead to eye inflammation, corneal erosion, ulceration, and vision loss if left untreated.

Low quality of life. Dry eyes make it difficult to perform daily activities, such as reading.



Avoid directing air into your eyes

Air humidification. A humidifier can increase the humidity of dry indoor air in winter.

Wearing sunglasses that cover the face or other protective eyewear

Rest your eyes while doing time-consuming tasks

Quit smoking and avoid secondhand smoke

Use artificial tears regularly


Treatment or treatment

Because dry eyes can be chronic, there are some medications used to relieve symptoms, including Using artificial tears, which are eye drops that contain a solution similar to eye tears, and you can buy them without a prescription. The doctor may block the tear ducts in the eye to preserve the natural tears for as long as possible
