Written by HealthAnswers editorial team Medically reviewed by [HealthAnswers UK doctor review panel](https://healthanswers.co.uk/our-doctors/) Reviewed 3 July 2026 ## Quick answer What could itchy eyes mean? Itchy eyes are most often caused by hay fever or other allergies that make the eyes itchy, watery and red. Dry eye and blepharitis (crusty eyelids) are other common causes. Simple allergic itch usually settles with antihistamine drops and avoiding triggers, but a painful red eye with vision change needs same-day medical assessment. ## Who is this page for?

On this page 4 sections ## Common causes of itchy eyes - Hay fever and other allergies are the most common cause of itchy eyes. - Blepharitis causes crusty, inflamed eyelid margins alongside itching. - Try not to rub itchy eyes, as this can worsen irritation and swelling. - Contact lens wearers with a red eye should remove their lenses and seek advice. - Vision loss combined with eye pain is a medical emergency. ## Understanding itchy eyes Itchy eyes are a common complaint, and allergy is by far the most frequent cause. The itching itself is rarely a cause for concern, but how urgently you need help depends on whether pain or changes in vision are also present. ## Causes of itchy eyes **Hay fever** and other allergies are the most common triggers, causing itchy, watery and often red eyes. **Dry eye** can also produce a similar itchy, gritty sensation. **Blepharitis**, inflammation of the eyelid margins, causes itching alongside crusty or sticky eyelids. **Infective conjunctivitis**, an infection of the surface of the eye, is another cause and often produces sticky discharge as well as itching. ## Self-care for itchy eyes A cold compress held against closed eyes can soothe itching and reduce swelling. Antihistamine eye drops, available from a pharmacist, are effective for allergic itchy eyes. Wearing sunglasses during pollen season helps reduce your exposure to the allergens that trigger symptoms. ## When to see a GP about itchy eyes A painful red eye should be assessed the same day rather than left to settle on its own. Contact lens wearers who develop a red or painful eye should remove their lenses immediately and seek assessment. ## ! When to get medical help for itchy eyes See a GP or optician if itchy eyes persist despite self-care or keep coming back. Call **999** or go to A&E for severe eye pain or sudden vision loss. Call **111** for urgent advice when you are unsure what to do. ## Common questions about itchy eyes Why do my eyes get itchy in spring? Spring itchy eyes are usually caused by allergic conjunctivitis triggered by pollen. Antihistamine eye drops can relieve the itching and redness, and wearing sunglasses outdoors helps reduce pollen exposure. What causes itchy eyes without allergies? Dry eye is a common non-allergic cause of itchy eyes and can feel gritty as well as itchy. Artificial tears and good eyelid hygiene are the main ways to ease the itching. Are decongestant eye drops safe to use long-term? Decongestant eye drops should not be used for long periods, because prolonged use can cause rebound redness once the drops wear off. Use them only as directed and speak to a pharmacist if you need them regularly. What are the red flag symptoms for itchy eyes? Eye pain, sensitivity to light, or any loss of vision alongside itching are red flag symptoms. These need an urgent eye assessment rather than routine self-care. ## Sources - [NHS — Itchy Eyes](https://www.nhs.uk/conditions/itchy-eyes) - [NHS — Hay Fever](https://www.nhs.uk/conditions/hay-fever)
