What Causes Dry Eye and How It’s Diagnosed

Dry eye disease is a common yet complex condition that can significantly impact daily comfort and vision. While symptoms may seem straightforward, dry eye often results from underlying eyelid and tear film disorders. A thorough diagnosis is critical to identifying the root cause and determining the most effective treatment approach. At Blinking Owl Eye Care, we take a personalized approach to identifying the root cause of dry eye so we can recommend treatments that actually work.

What Is Dry Eye?

Dry eye occurs when your eyes don’t produce enough tears, or when the tears you do produce evaporate too quickly or lack proper balance. Healthy tears are made up of three layers - oil, water, and mucus. If any of these layers are disrupted, dryness, irritation, and inflammation can occur.

Common Causes of Dry Eye

One of the most common causes of dry eye is Meibomian Gland Dysfunction (MGD). The meibomian glands, located along the eyelids, produce the oily layer of the tear film that helps keep tears from evaporating too quickly. When these glands become blocked or stop working properly, tears evaporate faster than they should, leading to dryness, irritation, and ongoing inflammation.

Another frequent contributor to dry eye is blepharitis, a chronic inflammation of the eyelids often caused by bacteria, skin conditions, or excess oil buildup. Blepharitis commonly occurs alongside MGD and can further disrupt the quality of the tear film. Symptoms such as red or swollen eyelids, crusting along the lashes, and burning or itching sensations are common. Without proper treatment, blepharitis can continue to worsen dry eye symptoms and interfere with long-term eye comfort.

Other Contributing Factors

Dry eye can also be influenced by a variety of lifestyle, environmental, and health-related factors, including:

• Prolonged screen use and reduced blinking
• Aging and hormonal changes
• Certain medications (such as antihistamines or antidepressants)
• Contact lens wear
• Autoimmune conditions
• Environmental factors like wind, dry air, or smoke

Because dry eye often has multiple contributing causes, a one-size-fits-all solution rarely works.

How Dry Eye Is Diagnosed

Proper diagnosis is essential for effective treatment. At Blinking Owl Eye Care, diagnosing dry eye goes beyond asking about symptoms.

Our eye doctor carefully evaluates:

• Tear quality and stability
• Meibomian gland function
• Eyelid health and signs of inflammation
• Tear evaporation and surface damage

By identifying whether dry eye is driven by MGD, blepharitis, inflammation, or a combination of factors, we can create a treatment plan tailored specifically to your eyes.
