Along with congestion, runny nose, coughing, sneezing, headaches and difficulty breathing, individuals with allergies often suffer from eye allergies or allergic conjunctivitis resulting in red, watery, itchy and sometimes swollen eyes.
What is an Eye Allergy?
Just as irritants cause an allergic response in your nasal and respiratory system, your eyes also react with an oversensitive immune response, triggered by an environmental substance that most people’s immune systems ignore.
Most individuals with allergies also suffer from eye allergies which affect millions of North Americans, particularly with seasonal allergic conjunctivitis (SAC) which is common during the spring, summer and fall.
What Causes An Eye Allergy?
Eye allergies, or any allergies for that matter, occur when the immune system is hypersensitized to a stimulus in the environment that comes into contact with the eye. The allergen stimulates the antibodies in the cells of your eyes to respond by releasing histamine and other chemicals that cause the eyes and surrounding tissue to become inflamed, red, watery, burning and itchy.
Eye allergens can include:
- Airborne substances found in nature such as pollen from flowers, grass or trees.
- Indoor allergens such as pet dander, dust or mold.
- Irritants such as cosmetics, chemicals, cigarette smoke, or perfume.
