Dry eye syndrome is caused by a persistent lack of adequate lubrication and wetness on the surface of the eye.
Its consequences range from subtle however continuous irritation to inflammation of the anterior (front) tissues of the eye.
Dry Eye Symptoms
Relentless dryness, scratchiness, red eyes and a burning sensation are common symptoms of dry eyes. These signs alone may prompt your optometrist to detect dry eye syndrome.
However, sometimes your optometrist may want to measure the amount of splits in your eyes. A thin strip of filter paper put under the lower eyelid, called a Schirmer test, is one way to determine tear production.
Another sign of dry eyes is a "foreign object experience," which is a feeling that something is in your eye.
And it might appear odd, but dry eye syndrome also can trigger watery eyes. Because dryness on the eye's surface sometimes will overstimulate production of the watery element of your splits as a safety system.
What Triggers Dry Eyes?
Tears shower the eye, washing out dust and debris and keeping the eye moist. They also consist of enzymes that reduce the effects of microorganisms that colonize the eye. Tears are essential for good eye health.
Dry eye syndrome has great deals of causes.
- Normal Aging Process
- Certain medications can cause dry eyes.
- Dirty or Windy Environment
- Not blinking (from staring at a computer screen)
Current research study shows that contact lens wear and dry eyes can be a vicious circle. Dry eye syndrome makes contact lenses feel unpleasant, and evaporation of wetness from contact lenses intensifies dry eye symptoms. More recent contact lens materials and lens care items can help in reducing contact lens dryness.
Insufficient closure of the eyelids, eyelid disease and a deficiency of the tear-producing glands are other causes.
Current research suggests that cigarette smoking, too, can increase your danger of dry eyes.
With increased popularity of cosmetic eyelid surgical treatment (blepharoplasty) for improved look, dry eye grievances now periodically are associated with the insufficient closure of eyelids following such a treatment.
