Seasonal allergies and dry eye are often hard to tell apart, as they tend to have overlapping symptoms. Fortunately, there are key differences that can point you in the right diagnostic direction.
The answer to whether you have dry eyes or allergies often depends on whether your primary symptom is a persistent itch, a classic sign of allergies, or more of a burning or stinging feeling, which is common with dry eye. However, if you’re still not sure, our team at Calgary Family Eye Doctors can take a look at your eyes and identify the cause of your discomfort.
Spot the Differences
Paying close attention to what your eyes feel like can offer the first clue. While there is some overlap between them, dry eyes and allergies have different primary symptoms.
- Itchiness: If you have an overwhelming urge to rub your eyes, allergies are the more likely cause. In fact, itchiness is the number one complaint for eye allergies.
- Burning or Stinging: A feeling of sand or grit in your eye points towards dry eye.
- Watery Eyes: This one is tricky because both conditions can cause your eyes to tear up. With allergies, it’s a reaction to an irritant, which can sometimes lead to allergic conjunctivitis, while with dry eye, it can be your body’s attempt to lubricate your eyes.
Check for Other Clues & Patterns
Think about when and how your symptoms appear. The context surrounding your eye discomfort can reveal a lot about the potential cause.
When Do Your Symptoms Act Up?
Determine whether there’s a pattern to your irritation. Allergy symptoms often pop up during certain times of the year, like when pollen counts are high in the spring or fall. On the other hand, dry eye symptoms may get worse after long hours of computer work, reading, or being in a dry, windy environment.
Do You Have Other Symptoms?
Consider what else is happening with your body. Allergies rarely just affect your eyes. You might also have a stuffy or runny nose, sneezing, or an itchy throat. Dry eye symptoms are usually limited to your eyes and vision.
The Main Cause of Your Discomfort
What Happens with Dry Eyes
Dry eye occurs for one of two main reasons. Either your eyes aren’t producing enough tears to stay moist, or the tears that they do produce are of poor quality. Healthy tears need the right balance of water, oil, and mucus to properly protect and nourish your eyes. If that balance is off, your tears evaporate too quickly. This is often related to blockages of the oil-producing glands in your eyelids.
What Happens with Allergies
Eye allergies are an immune system response. When you encounter an allergen—like pollen, pet dander, or dust mites—your body overreacts, releasing substances called histamines. Histamines cause your blood vessels to swell, leading to itchy, red, and watery eyes.
Simple At-Home Relief & Care
You can take steps at home to get some temporary relief, no matter the cause of your discomfort.
Tips for Both Conditions
A few simple habits can help soothe general eye irritation.
- Try your best to avoid rubbing your eyes, as this can make both conditions worse.
- Using a humidifier can add moisture to the air in your home, which is especially helpful for managing dry eyes in winter.
- Taking regular breaks from your screen gives your eyes a chance to recover from the strain of constant focusing.
Targeted Relief Methods
A cool compress placed over closed eyes can help calm the itchiness caused by allergies. In contrast, a warm compress may help soothe the irritation caused by some forms of dry eye.
How Your Eye Doctor Can Help
While at-home care can provide comfort, getting to the root of the problem is the best path to lasting relief.

Knowing what you’re dealing with means you can start with the right treatment. An accurate diagnosis also helps rule out other eye health conditions.
