Symptoms of Dry Eye

Tears are an essential bodily function that aids in the functioning and health of our eyes. The lacrimal glands located above the eyes produce tears, which serve various functions. They play a critical role in lubricating and moisturizing the eyes. That keeps the eye's surface smooth and clear. 

Tears also help protect the eyes against injury and infection. They contain antibodies and other proteins that help the body fight viral and bacterial infections. Furthermore, they have enzymes that can aid in breaking down and removing foreign particles that may enter the eyes.

What Is Dry Eye Syndrome?

Dry eye syndrome, or keratoconjunctivitis sicca, results from a deficiency in tear production. It occurs when the eyes don't generate enough tears or the tears they produce aren't good quality. That can lead to symptoms like dryness, redness, itchiness, burning, and a feeling of grittiness or foreign body sensation in the eyes. In severe cases, it can damage the cornea and affect vision.

Symptoms

Dry eye disease can cause a wide range of symptoms, ranging from mild to severe. Among the most prevalent signs are the following:

Inflammation or Redness of the Eyes

When the eyes are dry and irritated, inflammation is a typical response. Blood vessels in the eyes can dilate and become red, giving the eyes a bloodshot appearance.

Dryness, Grittiness, Itchiness, or a Foreign Body Sensation in the Eyes

The surface of the eye can become dry and irritated if not adequately lubricated with tears. That can cause discomfort, itchiness, and a foreign or gritty sensation in the eye.

Light Sensitivity

Dry eyes are more sensitive to light, which can cause pain and discomfort when exposed to bright light.

Blurred Vision or Difficulty With Visual Tasks 

When the tear film on the eye's surface is inadequate, it can affect light refraction, resulting in fluctuating or blurry vision. Furthermore, dry eyes can make it challenging to keep the eyes open. You may experience a burning sensation when they are open, causing you to close them more frequently. That can make it difficult to focus and concentrate.

Stinging or Burning Sensations in the Eyes

As the eye dries, it may become irritated, resulting in a burning or stinging sensation.

Difficulty Wearing Contact Lenses

The use of contact lenses can be challenging for people with dry eyes. The lenses can become dry and uncomfortable, causing blurred vision and irritation.

Excessive Tearing or Watery Eyes 

When the eyes are dry, the body may attempt to lubricate them by producing more tears. That can lead to watery eyes, which can be misleading.

Discharge or Crusting in the Eyes

When the eyes are dry, the eyelids can stick together at night, resulting in crusting or discharge from the eyes in the morning.

A Sensation of Something in the Eyes

The dryness and irritation caused by dry eye disease can cause a sensation of something in the eyes and discomfort or pain.

Conclusion

If you suspect you have dry eye, see an eye doctor as soon as possible. If left untreated, dry eye can lead to more severe problems, such as corneal scarring or infection.
