What Are Eye Allergies? Symptoms, Causes, and Treatment

What Causes Eye Allergies?

Eye allergies, also known as allergic conjunctivitis, are triggered when the eyes come into contact with various allergens, leading to an immune response, according to WebMD. Understanding the specific triggers can help in managing and preventing the uncomfortable symptoms associated with this condition.

Some of the most common allergens for eye allergies, according to WebMD, include:

• Pollen

• Dust mites

• Trees

• Grasses

• Weeds

• Mold spores

• Smoke

• Pet dander

These substances can cause the body's immune system to overreact, releasing histamines and other chemicals that lead to inflammation and irritation of the conjunctiva—the clear tissue covering the white part of the eye and the inside of the eyelids—according to WebMD. They explain that this reaction is the body's way of trying to protect itself from what it perceives as harmful invaders, even though these allergens are generally harmless to most people.

What Are the Symptoms of Eye Allergies?

Allergic Conjunctivitis can cause a range of uncomfortable symptoms that impact daily life. Recognizing these symptoms can help in seeking timely treatment and managing the condition effectively.

Common symptoms of eye allergies, according to WebMD, include:

• Redness

• Itchiness

• Burning feeling

• Watery eyes

• Swollen eyelids

• Feeling like there is dirt or grit in your eyes

What Is the Treatment for Eye Allergies?

Treating Allergic Conjunctivitis involves a combination of strategies to alleviate symptoms and reduce exposure to allergens, according to the American Academy of Ophthalmology (AAO). They note that depending on the severity of the condition, various treatments can be employed to provide relief and manage the symptoms effectively.

Here are some common treatment options for Allergic Conjunctivitis, as noted by the AAO:

• Saline eye drops to wash away the allergens: These drops help rinse out allergens and irritants from the eyes, providing immediate relief and reducing redness and itching.

• Over-the-counter medicine or eye drops (short-term use): Antihistamine eye drops or oral medications can help control mild to moderate symptoms. However, they are generally recommended for short-term use to avoid potential side effects.

• Prescription treatments from your doctor: For more severe cases, a doctor may prescribe stronger antihistamine or anti-inflammatory eye drops, as well as oral medications to manage symptoms more effectively.

• Allergy shots (immunotherapy) from your doctor: For long-term relief, immunotherapy can help desensitize the immune system to specific allergens, reducing the frequency and severity of allergic reactions over time.

How Can I Prevent Eye Allergies?

Preventing eye allergies involves taking proactive steps to minimize exposure to allergens and maintaining good hygiene practices, according to the American College of Asthma, Allergy, and Immunology (ACAAI). They note that by implementing these strategies, you can significantly reduce the likelihood of experiencing uncomfortable symptoms.

Here are some effective ways to prevent Allergic Conjunctivitis, as recommended by the ACAAI:

• Don’t touch or rub your eye(s): Touching or rubbing your eyes can transfer allergens and irritants from your hands to your eyes, exacerbating symptoms.

• Wash your hands often with soap and water: Regular handwashing helps remove allergens and reduces the risk of transferring them to your eyes.

• Use a vacuum with a CERTIFIED asthma & allergy-friendly filter: This helps to reduce exposure to dust mites, pet dander, and other allergens in your home environment.

• Wash your bed linens and pillowcases in hot water and detergent: Regularly washing bedding in hot water helps eliminate allergens such as dust mites and pet dander.

• Use allergen covers (encasements) for pillows, comforters, duvets, and mattresses: These covers can significantly reduce the accumulation of allergens in your bedding.

• Keep pets out of the bedroom: Reducing pet dander in your sleeping area can help alleviate allergy symptoms.

• Wear sunglasses and a wide-brimmed hat: These can help shield your eyes from pollen and other airborne allergens when you are outdoors.

• Keep windows closed during high pollen and mold seasons: Using air conditioning and CERTIFIED air filters in your home and car can help maintain a cleaner indoor environment by filtering out allergens.
