An allergy is an overreaction by the immune system by normally harmless subjects known as allergens. Although there are many potential allergens, eye allergies are most commonly caused by pollen, dust, and pet dander. Food allergies and allergic reactions to insect venom typically do not affect the eyes as severely as airborne allergens. Watch the video for more information on eye allergies.
An allergy is an overreaction by the immune system by normally harmless subjects called allergens. Most people will suffer from at least one allergic reaction at some point in their life.
The most common allergens are pollen, dust mites, pet dander, insect venom, and food.
Symptoms may include:
red, watery, itchy eyes
running or stuffy nose
shortness of breath
in sever cases an asthma attack can occur.
While there is no cure, there are ways to prevent or relieve allergy symptoms such as avoiding specific allergens, taking medication, or immunotherapy.
