What Allergens Can Cause Itchy Eyes?

Eye allergies develop when your immune system overreacts to certain substances that are typically harmless, causing inflammation and irritation. These substances, or allergens, can be found in both indoor and outdoor environments.

The five primary allergens that may trigger itchy eyes include:

• Pollen from trees, grasses and weeds that can cause seasonal eye allergies; pollen season varies depending on where you live 
• Dust mites, microscopic organisms found in bedding, mattresses, pillows, upholstered furniture and household dust
• Pet dander, tiny proteins present in skin flakes shed by cats, dogs and other animals with fur, hair or feathers that can become airborne or settle on household surfaces 
• Mold spores, microscopic cells released into the air by mold that commonly thrive in damp, humid environments such as basements, bathrooms and areas with leaks or outdoors in rotting leaves 
• Environmental and other irritants, such as smoke, smog, fragrances, cosmetics and chemical fumes, which can act as merely eye irritants or true allergens, depending on an individual’s particular sensitivities and immune system

What Are the Symptoms of Eye Allergies?

Common symptoms of eye allergies may include:

• Itchy eyes, typically the most noticeable symptom
• Redness or the appearance of bloodshot eyes
• Pronounced tearing or watery eyes
• Swollen eyelids or eye puffiness 
• A burning, gritty or irritated sensation, as though something is in your eyes

Some people with eye allergies may also experience sneezing, a runny or itchy nose or nasal congestion.

While itchy eyes are a common symptom of eye allergies, eye redness and irritation can sometimes be caused by eye infections or other conditions. 

It’s Important to seek prompt medical attention if you experience vision changes, eye pain, light sensitivity, severe redness or other concerning symptoms.

How Can You Prevent Itchy Eyes Caused by Allergies?

While it’s not possible to avoid allergens entirely, there are practical steps you can take to reduce your exposure and help prevent symptoms or lessen their severity. 

Recommendations include:

• Limiting pollen exposure. Regularly check pollen forecasts, keep windows closed and avoid spending excessive time outside when pollen counts are high, if possible, and wear sunglasses outdoors.
• Reducing dust mites. Regularly wash bedding, use allergen-resistant pillow and mattress covers and keep indoor surfaces clean and dust-free.
• Managing pet allergens. Keep pets out of your bedroom, wash your hands after touching them and clean surfaces where pet allergens accumulate. 
• Controlling mold. Repair leaks, manage excess moisture, use a dehumidifier in humid spaces and routinely clean damp areas to deter mold growth. 
• Avoiding rubbing your eyes. Although it may provide momentary relief, rubbing your eyes can worsen irritation and inflammation.

It’s also important to identify your triggers by keeping track of when your symptoms develop. For example, if your symptoms worsen after yardwork or spending time outdoors, you may have a pollen allergy; if you experience symptoms after making your bed, you may have a dust mite allergy. 

Knowing your triggers allows you to use the right prevention strategy for your specific situation. 

How Should You Treat Itchy Eyes Caused by Allergies?

If the prevention strategies discussed above don’t provide enough relief, there are treatments available that may help alleviate your allergy symptoms.

Treatment approaches for itchy eyes caused by allergies include:

• Artificial tears. Lubricating eye drops can help rinse allergens from the surface of your eyes and help ease irritation. 
• Cold compresses. A clean, cool washcloth over closed eyes can help soothe irritation, relieve itching and alleviate swelling. 

• Allergy eye drops. Over-the-counter antihistamine eye drops can help manage itchy eyes. We recommend you speak with us for guidance about the most appropriate options. 

• Oral allergy medications. If you have symptoms such as sneezing, runny nose or other allergy symptoms in addition to itchy eyes, antihistamines may help.

• Professional treatment. If your symptoms are severe, persistent or difficult to manage, we may recommend prescription treatments or allergy testing. 

If your eye allergy symptoms persist despite the prevention tips and treatment strategies we’ve discussed here, we encourage you to contact us for an appointment. We can help identify your triggers and recommend appropriate personalized care.
