What is Dry Eye Disease?

Dry Eye Disease, also known as Keratoconjunctivitis Sicca, is a chronic condition where your eyes do not produce enough tears, or the quality of tears is poor, leading to inflammation and discomfort. Tears are essential for maintaining the health of the front surface of the eye and ensuring clear vision. When tear production is compromised, it can result in symptoms ranging from mild irritation to significant inflammation, potentially affecting the quality of life.

What are the Symptoms of Dry Eyes?

Persistent Eye Dryness

A feeling of dryness, grittiness, or a sandy sensation in the eyes. A feeling of dryness, grittiness, or a sandy sensation in the eyes.

Redness

Irritated or inflamed eyes that may appear red.

Burning or Stinging

A burning sensation in the eyes, often accompanied by a stinging feeling.

Blurry Vision

Fluctuating vision, particularly during tasks requiring prolonged focus, such as reading or using a computer.

Sensitivity to Light (Photophobia)

Increased sensitivity to light, making it uncomfortable to be in bright environments.

Excessive Tearing

Paradoxically, dry eyes can trigger excessive tearing as a reflex response, although these tears often lack the necessary lubricating properties.

When to See a Doctor for Dry Eyes?

If you experience persistent eye dryness or any of the symptoms mentioned above, it is essential to consult an eye care professional. Prolonged dry eye disease symptoms can lead to complications such as eye infections, corneal damage, or severe discomfort that impacts daily activities. Early diagnosis and appropriate treatment can help manage symptoms effectively and prevent further complications.

What Causes Dry Eye Disease?

Dry Eye Disease can be attributed to several factors:

Age

The natural aging process reduces tear production, making individuals over 50 more susceptible.

Gender

Women, especially those undergoing hormonal changes due to pregnancy, menopause, or the use of birth control pills, are more likely to develop dry eyes.

Medications

Certain medications, including antihistamines, decongestants, blood pressure medications, and antidepressants, can reduce tear production.

Environmental Factors

Exposure to dry, windy, or smoky environments can exacerbate symptoms.

Prolonged Screen Time

Extended use of computers, smartphones, and other digital devices reduces blinking, leading to increased tear evaporation.

Medical Conditions

Autoimmune diseases such as Sjögren's syndrome, rheumatoid arthritis, and lupus can cause chronic dry eye. Diabetes and thyroid disorders are also associated with dry eye disease.

Types of Dry Eyes

Dry Eye Disease can be classified into two primary types

Aqueous Deficient Dry Eye
Aqueous Deficient Dry Eye

This occurs when the lacrimal glands fail to produce enough tears to maintain a healthy eye surface.

Evaporative Dry Eye
Evaporative Dry Eye

This type is caused by rapid tear evaporation due to inflammation of the Meibomian glands, which produce the oily layer of the tear film.

Risk Factors for Developing Dry Eye Disease

Several factors can increase the risk of developing Dry Eye Disease

Aging

Individuals over 50 years are at higher risk.

Gender

Women, especially those undergoing hormonal changes due to pregnancy, menopause, or the use of birth control pills, are more likely to develop dry eyes.

Contact Lens Use

Prolonged use of contact lenses can disrupt the tear film.

Environmental Conditions

Living in dry, windy, or high-altitude areas can increase the risk.

Medical History

Autoimmune diseases, diabetes, and thyroid disorders can elevate the risk.

Eye Surgery

Procedures like LASIK can temporarily reduce tear production.

Prevention of Dry Eyes

Preventing dry eyes involves adopting certain habits and lifestyle changes:

Blink Regularly

Especially when using digital devices, make a conscious effort to blink often to maintain tear film stability.

Use Humidifiers

Adding moisture to the air, especially in dry climates or during winter, can help reduce tear evaporation.

Protect Your Eyes

Wear sunglasses or goggles in windy or smoky environments to protect your eyes from irritants.

Stay Hydrated

Drink plenty of water to maintain overall hydration, which supports tear production.

Take Breaks

Follow the 20-20-20 rule when using screens—every 20 minutes, look at something 20 feet away for at least 20 seconds.

Avoid Smoking

Smoking can exacerbate dry eye symptoms by irritating the eyes and reducing tear production.

Conclusion

Dry Eye Disease or Eye Dryness is a common condition that can significantly impact daily life if left untreated. Recognizing the symptoms and understanding the causes and risk factors are essential steps in managing and preventing this condition. If you experience persistent eye dryness or discomfort, consult an eye care professional to explore the best treatment options and protect your eye health.
