Does allergic rhinitis cause itchy eyes?

The same exposure may cause sneezing, a runny or blocked nose, and an itchy throat. Eye symptoms often affect both eyes and may include watering, redness, or a gritty feeling.

Allergic rhinitis is an immune response to substances breathed in, such as pollen, dust mites, mould, or animal dander. When the response involves the eye surface, released inflammatory chemicals stimulate itching and increase tears. Rubbing can make redness and swelling worse and can irritate the surface further.

Allergy-related itching commonly appears with nasal symptoms and tends to follow exposure. Sticky discharge, marked pain, light sensitivity, or a change in vision is less typical and may point to another eye problem.

Try to reduce contact with the suspected trigger: keep windows closed when outdoor pollen is high, wash your face after being outdoors, and avoid rubbing your eyes. A cool, clean compress can soothe irritation. Lubricating eye drops may help wash allergens from the surface.

A pharmacist or clinician can advise whether an antihistamine or allergy-specific eye drop is suitable for you, especially if you wear contact lenses, are pregnant, or take other medicines. Follow the product directions and remove contact lenses if the eyes are irritated.

Seek prompt medical assessment for eye pain, new blurred or reduced vision, strong sensitivity to light, an injury, or a feeling that something is stuck in the eye. Arrange a clinical review if symptoms persist, keep returning, or do not improve with sensible allergy measures.

Get urgent help if eye swelling occurs with breathing difficulty, throat tightness, faintness, or swelling of the lips or tongue, as these can signal a serious allergic reaction.

You could ask: Could allergies explain my eye and nose symptoms? Which triggers should I consider? Is an eye drop or nasal treatment appropriate for me? What symptoms would mean I need an eye examination?
