Causes of itchy eye
Itchy eyes are most often related to allergies or other minor conditions. Often they can be treated at home, but you might sometimes need medical attention.
Hay fever
This is the most common cause of itchy eyes in New Zealand. Pollen from trees, flowers or grass can trigger an immune response from your body, including swelling and inflammation. It's very common ‑ over a fifth of people in New Zealand have hay fever.

Other allergies can also cause red, itchy eyes
like pet fur, dust mites or some medicines. If your eyes get itchy soon after starting something new (like birth control or antidepressants), speak to your doctor.
Other irritants around you
There are many things that can irritate your eyes and make them itchy. These include tobacco smoke, ash, dust, sand, workplace chemicals, alcohol, eye makeup and contact lens solutions.

Problems with contact lenses
If you wear contacts, improper usage might cause dry, itchy eyes. If you forget to clean your lenses, wear them for too long, or wear them in the water (among other things), this can irritate your eyes and cause itching.

Computer eye strain
Staring at a screen for an extended period can cause dry, itchy eyes. At Specsavers, we recommend the 20‑20‑20 rule ‑ every 20 minutes, look at something 20 metres away, for 20 seconds.

Skin issues
Eczema, dermatitis (skin irritation) and rashes on the skin around your eyes can cause itchiness that makes you want to rub them. You might also notice skin flaking.
Blepharitis
Blepharitis is a common eye condition that causes inflammation. One of the main symptoms is swelling, inflammation and itching along the edges of your eyelids. You might also notice your eyelids get stuck together.

Conjunctivitis is a common infection of the thin membrane that covers the front of your eye and the inner surface of the eyelids.

Dry eye syndrome
If your eyes don’t produce enough tears, or the tears aren’t of the right quality to keep your eyes properly lubricated, you can develop dry eye syndrome. It can lead to dryness and itchiness.

Other diseases
There are a few other conditions that can cause itchy eyes (among other symptoms), though these are less common. Sjögren's syndrome, keratoconjunctivitis, and the autoimmune disease lupus can all cause red, itchy eyes.
