Eye Allergies

9/17/2014

If your eyes itch, are red, tearing or burning, pay attention to what they may be telling you. You may have eye allergies, or allergic conjunctivitis, a condition that affects millions of people each year. It is a condition that can occur alone, but often accompanies nasal allergy symptoms, such as sneezing, sniffling and a stuffy nose. And, while most people treat nasal allergy symptoms, they often ignore their itchy, red, watery eyes. 

Eye allergy triggers

Allergens that may be present indoors or outdoors can cause eye allergies. The most common outdoor airborne allergens are grass, tree and weed pollens. People who are sensitive to these allergens suffer from seasonal allergic conjunctivitis, the most common type of eye allergy.

Pet hair or dander, dust mites and molds are the most common indoor allergens. These indoor allergens can trigger symptoms for some people throughout the year, resulting in perennial allergic conjunctivitis.

Cigarette smoke, perfume and diesel exhaust may inflame your eyes. They can act as irritants that cause non-allergic symptoms, or they can make your allergic response worse.

Eye allergy causes

Just like hay fever and skin rashes, eye allergies develop when the body's immune system becomes sensitized and overreacts to something that is ordinarily harmless. An allergic reaction can occur whenever that "something" - called an allergen - comes into contact with your eyes. The allergen causes certain cells in the eye (called mast cells) to release histamine and other substances or chemicals that cause blood vessels in the eyes to swell, and the eyes to become itchy, red and watery.

Can eye allergies harm my eyesight?

Eye allergies, specifically allergic conjunctivitis, can be extremely annoying and uncomfortable, and they may disrupt your day-to-day activities, but they usually do not harm your eyes. However, there are rare conditions that are associated with atopic dermatitis (eczema) and other diseases can cause inflammation that may affect the eyesight. Chronic forms of eye allergy may also be caused by application of eye drops and creams, or even cosmetics.

What to do if you are unsure? 

More than likely a simple antihistamine can help with your symptoms, but in cases where the allergy symptoms are persistent or unbearable, we can have a look for you and let you know what you can do to make the symptoms better. Book your appointment by calling  (905) 751-0169.
