What causes an eye allergy?

Outdoor allergens 

Airborne allergens such as grass, tree and weed pollen can affect your eyes. Individuals who are sensitive to them can suffer from a seasonal eye infection called allergic conjunctivitis. It is the most common eye allergy.

Indoor allergens

Other common eye allergens include pet hair, mould found in moist rooms, pollution and dust mites. These can trigger symptoms for people all year-round.


Some people are also triggered by irritants such as perfume, cigarette smoke and fumes from a car exhaust pipe.


Contact lenses

If you wear contact lenses you may find that you react badly to the actual contact lenses itself or to the tear film that binds to the surface of the lens. Talk to your optometrist about hyper-allergenic alternatives.


Allergic reactions to medications are common and must be monitored. They are strong and intense reactions and can be caused by Penicillin or preservatives in eye drops.

How to stop itchy eyes and treat allergies?


  • Avoid places or things that trigger your allergies
  • Start with making changes in your environment including shutting the windows during allergy season
  • Wearing glasses to protect your eyes from pollen
  • Wash your hands after petting animals
  • Use humidifiers and mite-proof bedding depending on your particular allergies

Over-the-counter medication 

Antihistamines, eyes drops and artificial tears are all non-prescription medication that can help to ease symptoms.

Prescription medication

Many optometrists may prescribe eye drops and other prescription medication for more severe symptoms. You do not need a referral to see an optometrist.
