Pink eye, also called conjunctivitis, is an inflammation of the lining in the eyelid and the white portion of the eye. The inflammation occurs due to a viral or bacterial infection, a blocked tear duct in infants or from an allergy. Allergic pink eye occurs because of a reaction to the direct contact of an allergen. Common triggers for eye allergies include pollen, dust and pet dander. Allergy eye drops help treat the condition. Symptoms of allergic pink eye are similar to the symptoms of pink eye caused by an infection.
Seasonal Symptoms
Allergic pink eye causes symptoms during times of high exposure to allergies. Spring is a time when the pollen count increases drastically and causes symptoms of pink eye. Some individual may still suffer from allergic pink eye if the allergen is not seasonal, such as pet dander or dust.
Watery Eyes
With allergic pink eye, the eyes water and tear without purulent drainage. The discharge with the allergic form of pink eye is normally clear. This normally affects both eyes.
Redness
The white portion of the eye and the pink areas of the eyelid lining become inflamed and reddened in both eyes. The redness of the sclera is what gives this condition the pink eye moniker. The irritation may prevent wearing contact lenses comfortably.
Swelling
Swelling of the eyelid may occur during episodes of allergic pink eye. The same areas of the eye and eyelid affected by the redness may also become inflamed and swell slightly. The edema may make it difficult to opening the eyes fully.
Itching
Allergic pink eye causes itching. The itching occurs in both eyes. The extreme itching may cause discomfort to the skin surrounding the eye.
Nasal Problems
Along with the itching, tearing and redness in the eyes, a stuffy, runny or itchy nose may accompany allergic conjunctivitis.
Not Contagious
Unlike a viral form of pink eye, allergic conjunctivitis does not spread between individuals. This form of pink eye is not contagious, according to Kids Health, a service of The Nemours Center for Children's Health Media.
