Itchy, red, watery eyes are a common complaint—especially during allergy season.
At Prairie Eye Care Edmonton, we often hear the same questions from patients who aren’t sure whether their symptoms are due to allergies, infection, or something else. Here’s everything you need to know about eye allergies.
General Understanding
What are eye allergies?
Eye allergies, or allergic conjunctivitis, occur when your eyes react to allergens like pollen, dust, or pet dander. Your immune system sees these substances as threats, releasing histamine and triggering symptoms like redness and itching.
What causes eye allergies?
Common causes include pollen, dust mites, mold, pet dander, and smoke. Certain cosmetics or eye drops can also act as irritants.
Are eye allergies contagious?
No. Unlike viral or bacterial conjunctivitis (pink eye), allergic conjunctivitis is not contagious.
How are they different from pink eye?
Pink eye caused by infections often includes yellow or green discharge, pain, and can be highly contagious. Allergies usually involve clear tearing, itchiness, and occur in both eyes.
Symptoms
What are the symptoms of eye allergies?
Redness, itching, watery eyes, light sensitivity, and a burning or gritty sensation are all common.
How do I know if it’s allergies or something else?
If symptoms come on suddenly, happen in both eyes, and occur seasonally or around allergens, it's likely an allergy. An optometrist can help confirm this.
Can it affect only one eye?
Typically, allergies affect both eyes, but one may be more irritated than the other.
Can eye allergies cause blurry vision?
Yes, excessive tearing and inflammation may blur your vision temporarily, especially during flare-ups.
Causes and Triggers
What are the most common triggers?
Pollen, dust, pet dander, smoke, mold, and cosmetics.
Can seasonal allergies affect eyes?
Absolutely—pollen is one of the most common triggers for allergic eye symptoms.
Do contact lenses make allergies worse?
Yes. They can trap allergens, worsening symptoms. Daily disposable lenses may help reduce irritation.
Diagnosis and Treatment
How are eye allergies diagnosed?
An optometrist evaluates your symptoms and may perform tests to confirm the diagnosis.
What treatments are available?
Options include antihistamine or mast-cell stabilizing eye drops, oral allergy meds, and prescription drops for severe cases.
Do over-the-counter drops work?
Many provide relief, but it’s best to consult an optometrist to ensure you're using the right type.
When should I see a doctor?
If your symptoms persist, worsen, or affect your daily life, book an appointment for a thorough eye exam.
Prevention and Management
How can I prevent flare-ups?
Stay indoors on high-pollen days, use air filters, avoid rubbing your eyes, and wash your hands frequently.
Should I avoid contacts during allergy season?
Yes, or switch to daily disposables. Your optometrist can suggest the best solution.
Can I wear makeup with eye allergies?
Use hypoallergenic, fragrance-free products. Discontinue if irritation occurs.
Are lifestyle changes helpful?
Definitely. Keeping your home allergen-free, wearing sunglasses outdoors, and maintaining good eye hygiene can all help reduce symptoms.
