Symptoms of Ocular Allergies

woman sneezing in field of flowers, eye doctor, spring, TXIn addition to congestion, runny nose, wheezing and sneezing, many allergy sufferers are subject to allergy symptoms in their eyes.

Allergic conjunctivitis is the scientific name for this condition. It is caused, like any allergic reaction, by a mistaken triggering of your body's immune system. Allergens cause your immune system “panic” causing it to react negatively to things which actually pose no harm to the body at all. Allergens such as pet dander, pollen and dust can trigger this reaction. This allergic reaction releases a chemical called histamine, which makes your eyes dry out and produce more tears. This reaction is meant to flush out foreign objects. The blood vessels in your eyes also become inflamed, which is what gives your eyes their bloodshot look.

Symptoms of an allergic reaction can be quite varied. You may find that your eyes are red and irritated or itchy, that your eyes are sensitive to light or that your eyelids are swollen. In more severe cases, you may even notice a painful, sore or burning feeling in your eyes or suffer from excessive tearing or a runny nose. This, of course, is in addition to the sneezing and stuffy nose.

Eye Allergy Causes

Many things may cause an allergic reaction. Grass, weed and tree pollen, as well as dust and pet dander, are among the best-known allergens. Less well known is that it is also possible for a person to be allergic to everyday items such as makeup or perfume, and even contact lenses. Also not well know is that, while it is very common for allergic symptoms to come out immediately upon contact with the allergen, it is also possible for an allergic reaction to present itself as much as four days after original contact with an allergen.

Treatment for Eye Allergies

Although allergies usually stop once the allergen is removed, and the eyes return to normal, this is not always possible with allergens such as dust and pollen, since they are just about everywhere. For these and other allergies, eye doctors recommend eye drops either over the counter or prescription. These eye drops should help to minimize the effects of the allergens in your environment. Many of these eye drops are formulated as antihistamines, meaning that they block histamine from the body. There are also a number of other ways that these eye drops will work to relieve or prevent allergic symptoms.

Artificial tears are also an excellent option to relieve dry eye symptoms caused by allergens. These eye drops are specially formulated to imitate the tears that the allergic reaction has dried up. Artificial tears are mostly by prescription and have proven to perform better in some cases than over the counter eye drops.

Several other ways to reduce or relieve symptoms exist as well. Wearing sunglasses when stepping outside helps block pollen, dust, and other outdoor allergens from getting in your eyes.

Contact Lenses & Allergies

Contact lenses can also irritate your eyes during allergy season. If you must wear contacts, many optometrists recommend daily disposable lenses. Dailies will minimize the dust and dander that can build up in your contacts, and ensure that you have a fresh pair every day. This can greatly reduce the symptoms of eye allergies.

Of course, you might consider taking a break from your contacts while allergies are at their worst. Wearing your glasses instead will eliminate the added build up of allergens in your eyes caused by contacts, as well as give you extra protection from dust and dander floating in the air. Way after it’s time for lights out at bedtime, many teens and students keep their electronic devices on and glowing.

Itchy Eyes? Don't Rub

And finally, never rub your eyes when you have eye allergies. This will only push the allergens deeper into your eyes, causing more discomfort and pain.
