Eye Allergy Overview
Also called allergic conjunctivitis or ocular allergy, eye allergy occurs when
something you are allergic to irritates the conjunctiva. This is the delicate
membrane covering the eye and the inside of the eyelid.
Like all allergies, allergic conjunctivitis starts when the immune system identifies
an otherwise harmless substance as an allergen. This causes your immune system
to overreact and produce antibodies called Immunoglobulin (IgE). These
antibodies travel to cells that release chemicals which cause an allergic reaction. In
this case, allergic reactions include eyes that water, itch, hurt or become red or
swollen.
The most common causes of allergic conjunctivitis are seasonal allergens such as
pollen and mold spores. People with seasonal allergic rhinitis (hay fever) normally
notice their symptoms worsen when they go outdoors on days with high pollen
counts.
Indoor allergens such as dust mites and pet dander can also cause eye allergies
year-round. If you suffer from this type of allergy, you may notice your symptoms
worsen during certain activities such as cleaning your house or grooming a pet.
Eye allergy symptoms can be very annoying. Yet they pose little threat to eyesight
other than temporary blurriness. Unlike conditions such as pink eye, allergic
conjunctivitis is not contagious.
However, red, itchy, burning and puffy eyes can be caused also by infections and
other conditions that can threaten eyesight.
