Can Allergies Affect Your Eyes? Symptoms and Solutions

Allergies are a common part of life for many Australians, especially during seasonal changes, but their impact extends beyond sneezing and congestion. For many people, allergies can significantly affect the eyes, leading to discomfort, irritation, and even blurred vision. At The Eyecare Spot, we see many patients each year struggling with allergy-related eye issues, and fortunately, effective relief is possible.

How Allergies Affect the Eyes

When your immune system overreacts to allergens like pollen, dust, mould, or pet dander it releases histamines and other chemicals. These substances trigger inflammation in the body—including the eyes. This condition is known as allergic conjunctivitis, and it’s one of the most common causes of red, itchy, watery eyes.

Unlike viral or bacterial conjunctivitis (often referred to as “pink eye”), allergic conjunctivitis is not contagious. However, it can be just as frustrating, particularly when symptoms persist throughout the day or worsen in specific environments.

Common Eye Allergy Symptoms

Allergy-related eye symptoms can vary in severity, but there are a few hallmark signs. Itching is often the first and most noticeable symptom, followed by redness, watering, and a burning or stinging sensation. Some people also experience swollen eyelids or a gritty feeling, as though something is stuck in the eye. In more severe cases, light sensitivity and blurred vision can develop, making daily tasks more difficult.

It’s also common for allergy symptoms to affect both eyes equally, unlike infections which often start in one eye before spreading.

Identifying the Triggers

Knowing what’s triggering your symptoms is key to managing them effectively. Pollen allergies tend to be seasonal, flaring up in spring or summer when airborne particles are most concentrated. Indoor allergens like dust mites, pet dander, and mould can cause year-round symptoms and may worsen in dry or poorly ventilated spaces.

Environmental factors like wind, air conditioning and smoke can also aggravate the eyes, even in people without a history of allergies. If you're unsure what's behind your symptoms a professional eye examination can help rule out other causes and confirm whether allergies are to blame.

Treatment and Relief Options

For mild to moderate symptoms, over-the-counter antihistamine or lubricating eye-drops can offer quick relief. These products help soothe irritation and flush out allergens from the eye surface. However, not all eye drops are created equal, and it’s important to choose the right formulation based on your individual symptoms.

If your eyes remain red and itchy despite using drops, you may need prescription-strength treatments or a tailored allergy management plan. At The Eyecare Spot, we offer guidance on how to relieve allergy symptoms and can recommend appropriate medical options based on your needs.

We also advise patients to avoid rubbing their eyes, as this can worsen inflammation and damage delicate tissues. Instead, using a cool compress over closed eyelids can provide immediate relief and reduce swelling.

Preventative Tips for Allergy Season

Minimising exposure to allergens is a key part of long-term relief. Keeping windows closed on high-pollen days, using air purifiers indoors and washing your hands and face after being outdoors can help reduce allergen contact. Contact lens wearers should also be extra cautious, as lenses can trap allergens and increase irritation. Switching to daily disposable lenses can make a big difference.

Wearing glasses during allergy season can offer a physical barrier between your eyes and airborne allergens, providing both comfort and protection. We also offer custom eyewear solutions that fit your lifestyle and reduce strain during high-risk months.

When to Seek Professional Care

If your symptoms persist, worsen or begin to interfere with your vision, it’s important to book an eye test. Eye allergies can sometimes mask other conditions, including dry eye syndrome or infections, which require different treatment. Our optometrists can identify the source of your irritation and recommend a targeted solution.
