Causes of itchy eye
Itchy eyes are most often related to allergies, but there are several other itchy eye causes. Some of them may need medical attention.
Hay fever
This is the most common cause of itchy eyes in Australia. Pollen from trees, flowers or grass can trigger an immune response from your body, including swelling and inflammation. It's very common ‑ about a quarter of people in Australia 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.
Environmental irritants
There are many things that can irritate your eyes and make them itchy. These include cigarette smoke, ash, dust, sand, workplace chemicals, alcohol, eye makeup and contact lens solutions.

Contact lens problems
If you wear contacts, incorrect usage might cause dry, itchy eyes. If you forget to properly clean your lenses, wear them for too long, or wear them while swimming (among other things), this can irritate your eyes and cause itching.

Screen usage
Looking at digital screens 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.

Dermatological issues
Eczema, dermatitis (skin irritation) and rashes that affect the skin near your eyes can cause itchiness around your eyes.
Blepharitis
This is a common eye condition that causes inflammation. You may get swelling, inflammation and itching along the edges of your eyelids. You might also notice your eyelids get stuck together.

Conjunctivitis
Also known as red eye or pink eye, conjunctivitis is caused by an infection of the thin membrane that covers the front of the eye and the inner surface of the eyelids.

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

Rarer diseases
There are several less common conditions that can cause itchy eyes (among other symptoms), though these are quite rare. Sjögren's syndrome can make eyes dry and itchy, keratoconjunctivitis can cause intense itchiness, and the autoimmune disease lupus can also cause dry, itchy eyes.
