Pollen allergies, also known as hay fever or seasonal allergies, are a common condition that affects millions of people around the world. When someone with a pollen allergy inhales pollen, their immune system mistakenly identifies it as a harmful substance and attacks it. This reaction releases histamine and other chemicals into the bloodstream, which can cause a variety of symptoms, including:
Itchy eyes
Red eyes
Watery eyes
Puffy eyelids
Swollen eyelids
Runny nose
Congested nose
Sneezing
Coughing
Fatigue
How Pollen Allergies Affect the Eyes
The eyes are particularly susceptible to pollen allergies because they are constantly exposed to the air. When pollen comes into contact with the eyes, it can cause the conjunctiva, the clear membrane that lines the eyelids and covers the whites of the eyes, to become inflamed. This inflammation is known as allergic conjunctivitis, and it is the most common type of eye allergy.
Symptoms of Allergic Conjunctivitis
The symptoms of allergic conjunctivitis can range from mild to severe. Common symptoms include:
Itchy eyes

Treatment for Allergic Conjunctivitis
There are a number of treatments available for allergic conjunctivitis. These include:
Over-the-counter antihistamines, such as loratadine (Claritin) and cetirizine (Zyrtec)
Prescription eye drops, such as cromolyn sodium (Optimase) and loteprednol etabonate (Lotemax)
