Dry Eye or Allergies? How Dr. Blew Helps Patients Tell the Difference

It is easy to confuse dry eye and eye allergies because both can cause irritation, redness, and watery eyes. However, the cause of the problem is not the same, which means the right treatment is not always the same either. At Michelle Blew, O.D., patients in Kennebunk can get answers when symptoms are persistent, uncomfortable, or affecting daily life.

Why Dry Eye and Allergies Seem So Similar

Both conditions can make your eyes feel irritated and look red. You may also notice tearing, blurry vision, or sensitivity throughout the day. The overlap in symptoms is one reason many patients try over-the-counter drops without knowing which condition they are actually treating.

The difference matters because dry eye often happens when your tears are not keeping the surface of the eye healthy, while allergies are typically triggered by environmental irritants like pollen, dust, or pet dander.

Signs It May Be Dry Eye

Dry eye symptoms often include burning, stinging, fluctuating vision, and a gritty sensation, as if something is in the eye. Some people also notice that their eyes water more, especially when the eyes are trying to compensate for dryness.

Symptoms may worsen with screen time, reading, driving, or time spent in air conditioning or heated indoor spaces. If discomfort feels ongoing rather than seasonal, dry eye may be part of the issue.

Signs It May Be Allergies

Allergies often cause itching more than burning. That is one of the clearest clues. Swelling, tearing, and irritation in both eyes are also common, especially during certain times of year or after exposure to known triggers.

Patients with eye allergies may also have sneezing, nasal congestion, or other allergy symptoms at the same time. When itching is the main complaint, allergies are often more likely than dry eye.

How Dr. Blew Identifies the Cause

A proper exam helps separate similar symptoms and uncover what is really happening on the eye’s surface. Dr. Blew evaluates tear quality, inflammation, eyelid health, and other factors that can point to dry eye, allergies, or even a combination of both.

This step is important because many patients do not have just one issue. In some cases, allergies can make dry eye worse, which is why a personalized diagnosis matters.

Treating the Source of Your Symptoms

When dry eye is linked to inflammation or meibomian gland dysfunction, treatment may go beyond basic artificial tears. Dr. Blew offers Intense Pulsed Light - IPL - as part of dry eye care to help improve gland function and support a healthier tear film.

Depending on your needs, your treatment plan may include:

• Targeted dry eye therapy such as IPL
• Recommendations for lid hygiene and at-home care
• Guidance on allergy management and trigger reduction
• Follow-up care to monitor symptom improvement

Relief Starts With the Right Diagnosis

Treating allergies when the real problem is dry eye can leave symptoms unresolved. The same is true when dry eye is mistaken for allergies. A focused eye exam can help patients get relief sooner and avoid the trial-and-error approach that often leads to frustration. For patients dealing with red, irritated, or watery eyes in Kennebunk, understanding the cause is the first step toward lasting comfort.
