Can Allergies Cause Dry Eyes?

With warmer weather comes more outdoor fun, but if you’re someone with seasonal allergies, this is one aspect of summer that can feel dreadful. 

A runny nose and constant watery eyes can turn an otherwise beautiful day into an uncomfortable battle between having fun and managing your allergies. Rubbing your itchy and swollen eyes might bring temporary relief, but in reality, it can cause more issues.

Allergies can absolutely cause or contribute to dry eyes. After exposure to an allergen, inflammation from the body’s immune response can lead to pesky dry eye symptoms. 

Don’t let allergies get in the way of your fun. In-office dry eye therapies can help you enjoy your summer without worry. 

Allergies & Your Eyes 

Constant environmental exposure makes your eyes particularly vulnerable to seasonal (or year-round) allergens like pollen, dust, and pet dander. 

When allergens come into contact with your eyes, your body’s immune system releases histamines, a chemical that causes inflammation and irritation. This is what leads to the telltale symptoms of redness, itchiness, a runny nose, and swelling. 

But there’s a catch. 

Allergic reactions often lead to increased tear production (think watery eyes), which may sound like the opposite of dryness. These tears, however, are mostly water and lack the oils produced by your meibomian glands. Without these oils, your tears evaporate too quickly from the eye’s surface, resulting in insufficient lubrication and, ironically, dry eyes. 

If you already struggle with dry eyes, allergies can exacerbate the condition, throwing your tear film off balance and worsening symptoms like grittiness and burning sensations.

Since dry eye and allergic reactions often share symptoms, it can be tricky to tell them apart. That said, some common signs of allergy-related dry eye include: 

  • Redness
  • Itchiness 
  • Swelling and inflammation
  • Constant irritation and burning sensation 
  • Excessive watering, followed by periods of dryness
  • A gritty feeling, as if there’s something stuck in your eye

Dry eyes can be irritating and uncomfortable, but they don’t cause sneezing, a runny nose, or nasal congestion. If you experience these symptoms along with itchy, red, or watery eyes, allergies are most likely to blame. 

Dry Eye Therapies for Allergy Relief

Despite your best efforts, allergy-related dry eye symptoms can persist. When over-the-counter solutions can’t provide the relief you’re after, it may be time to explore in-office dry eye therapies. 

Tackling allergy-related dry eyes is a multi-step process. At Brantford Eye Care, we adopt a comprehensive approach to dry eye management

These treatments aim to restore moisture, reduce inflammation, and stabilize the tear film. Here’s a closer look at some therapies we offer: 

  • Intense Pulsed Light (IPL) Therapy: Beyond helping with dry eye that stems from meibomian gland dysfunction, IPL reduces inflammation triggered by allergies, breaking the cycle of irritation and discomfort. 
  • Nutritional Support with Omega-3 Supplements: Quality omega-3 supplements in their triglyceride form can support healthy tear production and combat inflammation, significantly improving eye comfort. 
  • Allergy Management Strategies: We may recommend additional measures, such as prescription medications or lifestyle adjustments to limit allergen exposure. 

Dry eye therapy focuses on sustainable results. A blend of custom treatments and ongoing support from our team helps break the cycle of flare-ups, so you can enjoy clearer, comfortable vision without irritation. 

Most importantly, wash your hands, avoid touching your eyes, and please don’t rub your eyes for relief. These simple steps can make a noticeable difference in managing allergy-related dry eyes.

Can Antihistamines Worsen Dry Eyes? 

Here’s where things get tricky. 

Many people rely on antihistamines to fight allergy symptoms, and while they’re often effective, they can come with an unintended side effect: dry eyes. 

Antihistamines work by blocking histamines, which reduces allergic symptoms like watery eyes. However, they also decrease overall tear production, leaving your eyes vulnerable to dryness and irritation. 

You don’t have to swear off antihistamines to protect your eyes. Instead:

  • Use preservative-free artificial tears to add extra moisture to your eyes throughout the day. 
  • Ask your eye doctor to switch to allergy eye drops.
  • Pair your antihistamines (if your eye doctor approves) with in-office dry eye therapies to manage both conditions. 

If dry, itchy eyes are getting in the way of life, professional care can give you the solution you need.

How many doctors does it take to change a lightbulb?”

One or two.

Clear, comfortable vision is such an integral and important part of our lives. I enjoy interacting with our patients, learning about them and their visual needs and I get great satisfaction when I can improve their quality of life by providing them with optimal eyesight at the same time as screening for and treating potentially sight-threatening conditions.

I have been an optometrist at Brantford Eye Care (previously known as Dr. Robert Schumacher and associates) since 2002. I became the new owner of Brantford Eye Care in October 2012.

I attended the University of Ottawa where I studied Biochemistry as part of my undergraduate Bachelor of Science degree. I completed my Doctor of optometry (OD) degree at the University of Waterloo in 2002.

My externship was completed at the Houston Eye Associates in Texas. During that time, I gained extensive experience in all aspects of ocular health diagnosis and management. This included exposure to various retinal conditions, glaucoma, cataracts, children’s vision, binocular vision, and other aspects of ocular disease.

I worked as a student researcher at the Centre of Contact Lens Research at the School of Optometry, University of Waterloo where I gained extensive experience in all aspects of contact lenses. I also worked as a student researcher at the Ottawa General hospital in the Department of Ophthalmology during my university years.

I am an active member of the Ontario Association of Optometrists, The Canadian Association of Optometrists, the Ontario College of Optometrists, and the Hamilton and District Area Society of Optometrists. I am certified in the Treatment and Management of Ocular Diseases.

My main interests are in dry eyes, contact lenses, and in children’s vision. I have experience working as an optometrist at a Toronto LASIK centre and I am able to answer any questions you may have regarding LASIK and other refractive surgeries. We are affiliated with the various LASIK centres and can refer you for a complimentary LASIK consultation as well as perform your pre and post-op examinations at our office.

I enjoy many activities such as swimming, yoga, playing the piano, and spending time with my family. I enjoy solving visual issues and challenges and meeting new people.

I’ve been very fortunate to have met so many wonderful patients and families at our office. I enjoy being a part of Brantford’s health care team and look forward to seeing you at the office!
