Eye Allergies

Eye allergies, called allergic conjunctivitis, are a common condition that occurs when the eyes react to something that irritates them (called an allergen). The eyes produce histamine to fight off the allergen, resulting in the eyelids and conjunctiva becoming red, swollen and itchy, with tearing and burning.

The good news is that unlike bacterial or viral conjunctivitis, allergic conjunctivitis does not spread from one person to another.

People who suffer from eye allergies usually have nasal allergies as well, with an itchy, stuffy nose and sneezing. It is usually a temporary (acute) condition associated with seasonal allergies.

Eye allergies can also develop from exposure to other environmental triggers, such as pet dander, dust, smoke, perfumes, or even foods. If the exposure is ongoing, the allergies can be more severe, with significant burning and itching and even sensitivity to light.

The most common symptoms include: 

•   Red, swollen or itchy eyes
•   Burning or tearing of the eyes
•   Sensitivity to light

Many eye allergies are caused by the body’s response to allergens in the air both indoors and out. Some people can inherit eye allergies from their parents. In fact, you're more likely to have allergies if both of your parents have them than if only one does.
