Dry Eye and Allergies: Key Insights from Our Recent Webinar
Seasonal allergies used to be largely confined to the spring months, but in recent years, we are seeing an increasing number of patients coming into our office with allergies and related dry eye throughout the year. Understanding the connection between dry eye and allergies—and how to manage both—can provide significant relief for those struggling with these conditions.
We recently hosted a webinar on dry eye and allergies, led by our very own Dr. Lillie Mosaddegh and 9-time Emmy Award-winning journalist Cheryl Jennings. The session offered valuable insights into the relationship between these two common conditions and provided practical strategies for addressing them.

Are Dry Eyes and Allergies Related?
Dry eyes and allergies are often interconnected. In many cases, having one condition can lead to or exacerbate the other. Allergens such as pollen, dust, and pet dander can cause inflammation in the eyes, which in turn may trigger dry eye symptoms. Conversely, dry eyes can make the eyes more susceptible to allergic reactions, as the protective tear film becomes compromised. Understanding this cycle is key to effectively managing both conditions.
How Allergies Can Cause Dry Eyes
- Impaired Tear Glands: Allergic reactions in and around the eyes can lead to inflammation, which impairs the function of the tear glands. This results in insufficient tear production, leading to dryness and discomfort.
- Inflammation of Meibomian Glands: Allergies can cause inflammation of the meibomian glands, which produce oils that help stabilize the tear film and prevent evaporation. When these glands are inflamed, the tear film becomes less stable, contributing to dry eye symptoms.
- Excessive Tears: While it may seem counterintuitive, allergies can cause the eyes to produce excessive tears that lack the necessary oily layer, causing them to evaporate quickly. This evaporation leads to a persistent feeling of dryness and irritation.
- Increased Susceptibility: Dry eyes weaken the tear film’s protective barrier, making the eyes more vulnerable to allergens and irritants. Conversely, dry eyes can make the eyes more susceptible to allergic reactions, as the protective tear film becomes compromised. Understanding this cycle is key to effectively managing both conditions.
How Dry Eyes Can Worsen Allergies
- Compromised Tear Film: The tear film plays a crucial role in washing away allergens and irritants from the eyes. When the tear film is compromised due to dryness, it becomes less effective at this protective function, allowing allergens to cause or worsen allergic reactions.
- Inflammation and Irritation: Dry eyes can create a cycle of inflammation and irritation, which in turn can trigger or intensify allergic reactions, worsening the symptoms of both
conditions.
Dry Eyes vs. Allergies: How Their Symptoms Mimic Each Other
Dry eyes and allergies share many overlapping symptoms, such as redness, irritation,
intense itching, watery eyes, stinging, burning, blurry vision, and sensitivity to light. This
overlap can make it difficult to differentiate between the two conditions without a proper
diagnosis.
Self-diagnosing and treating these symptoms can sometimes worsen the situation. For example, antihistamines—which are commonly used to treat allergies—can exacerbate
dry eyes if the underlying issue is primarily dryness rather than an allergic reaction.
Consulting an eye care professional is crucial to ensure an accurate diagnosis and an
effective, personalized treatment plan.
