Can Seasonal Allergies Cause Blurry Vision

How Do Allergies Affect Your Eyes

Eye Allergy, Causes, Signs and Symptoms, Diagnosis and Treatment.


Allergies have an enormous impact on the health and well-being of the population. Each year, approximately 50 million Americans suffer from allergic diseases.


An allergy is the immune systems hypersensitive response to a harmless foreign substance in the body such as plant pollen, a certain food, or a drug. Whatever the foreign substance, or allergen, the immune system responds as if it were reacting to a real threat by triggering a specific type of immune response. This response can occur anywhere in the body.

An allergic response can cause the eyes to become inflamed. Your eyes may become increasingly red and itchy. The symptoms of eye allergies can vary greatly in severity and presentation from one person to the next. Most people will present with at least some degree of irritation or a foreign-body sensation. Many manifestations of allergy may be subtle and other eye conditions such as dry eyes and blepharitis may also contribute to worsen these symptoms.


Allergic conjunctivitis is the inflammation of the conjunctiva that is caused by an allergic reaction. The conjunctiva is the mucous membrane that covers the white of the eye and inner surface of the lids. Since the large majority of eye allergies involve the conjunctiva, the terms ocular allergy and allergic conjunctivitis are often used synonymously.

Symptoms include:

  • Itching and /or burning eyes

How To Treat Dry Eyes From Allergies

There are many different treatments for dry eye ranging from over-the-counter artificial tears to prescription medications to lid procedures. Dr. Schellenberg says finding the right treatment depends on the root of the problem.

The best way to differentiate dry eye syndrome from allergies is to first have an eye exam, as they can be difficult to manage without a treatment plan from an eye doctor.

Ocular allergies are often treated with antihistamine drops. There are several over-the-counter and some stronger prescription antihistamine drops available, she says. Additionally, steroid drops may be needed if ocular allergies are severe.

Since antihistamine drops can decrease tear production, your eye doctor may recommend using preservative-free artificial tears in conjunction with allergy drops to keep your eyes lubricating and from drying out.

Before trying medications, there are several simple things you can try to see if your symptoms improve. Avoiding allergens altogether can limit the histamine production, thus decreasing the dry, itchy feeling in your eyes.

This may sound easier said than done, but avoid going outdoors when pollen counts are higher early at dawn and dusk. Keeping windows closed during the summer can keep allergens from getting in your house. Clean your house regularly to remove dust and pet dander that collects on surfaces.

Symptoms Of Eye Allergies

Many people who complain about eye allergies experience itchiness as an immediate discomfort. However, others do not have itchiness but feel some eye fatigue and a burning sensation that causes them to rub their eyes. Other common allergy symptoms in the eyes include:

  • Burning sensation

Symptoms vary from person to person and depend on the complexity of the bodys reactions to the specific allergen. Expansion of blood vessels allows for a greater flow of allergic and inflammatory molecules from the bloodstream into the eye, where the reaction occurs.

If nasal allergies accompany these eye-related symptoms, you are likely to have a stuffy nose, a runny nose and a penchant for sneezing. Other likely reactions are coughing, a headache and a sore or itchy throat.

If you experience a stinging in the eyes, acute dryness or the feeling of a foreign object in your eyes, these could symptoms of dry-eye syndrome.

Can Allergies Cause Dry Eyes

Yes, allergies can contribute to dry eye. Dr. Schellenberg says antihistamine medications, which help treat allergies, decrease tear production. This decrease in tear production can lead to dry eye.

Chronic allergic conjunctivitis may also cause tissue changes in the glands within the eyelids, she says. This tissue change can result in the production of unhealthy tear components which leads to dry eyes.

Because they are so closely related, having dry eye can lead to eye allergies and having eye allergies can lead to dry eye. For example, pollen and other airborne particles associated with seasonal allergies can cause inflammation that triggers dry eye. On the other hand, people with existing dry eye syndrome have issues with tear production. Without an adequate tear film present to properly lubricate the eye, the eye cannot protect against allergens.

Swelling and inflammation can cause pressure on the eyes themselves, resulting in blurred vision. Infections can also cause inflammation of blood vessels, which can lead to blood clots that can block the blood supply to the brain. This can result in stroke, heart attack, or even death. In some cases, the infection can be so severe that the patient may not be able to breathe on his or her own.

Eye Allergies: Causes Symptoms & Treatments

Allergies can cause a range of physical reactions across your body, and the human eye is no exception. Some allergy sufferers ignore eye symptoms, choosing instead to focus on other effects like skin rashes and scratchy throats.

But overlooking the health impact of eye allergies can increase your risk of chronic complications like dry eye disease and vision loss.

Thanks to a range of eye drops and medications, you can manage the symptoms of eye allergies. Recognizing and addressing symptoms can be the key to reclaiming your quality of life.

Below, well explain how to spot eye allergy symptoms, and share some methods for treating them and avoiding eye allergy flare-ups.

Common Causes For Eye Allergies

Allergic responses can be caused by several agents. The most common are dust, pollen, pet danger, dust mites and smoke. Other irritants can include cleaning products, lawn care materials, eye makeup and hair care solutions. This means that there are many active sources for an allergic response. Your doctor can help you identify the source of the issue and treat your allergic response.

Differentiating Allergy And Dry Eye Symptoms

The main difference in symptoms between dry eye and allergic conjunctivitis is intense itching. While itching may occur with dry eyes, it is usually more intense with allergic conjunctivitis. Any itching associated with a runny nose or watery eyes also is a sign it is related to allergies.

Still, Dr. Schellenberg notes there are many symptoms that overlap between dry eye and allergic conjunctivitis.

Allergic conjunctivitis may cause ocular redness, watery eyes, mucus discharge, swelling or puffiness around the eyelids, blurry vision, and sensitivity to light, she says. Itching is also present, and there may be an intense urge to rub the eyes.

Dry eyes have a more varied set of symptoms. The symptoms include scratchy sensation, feeling like something is in the eye, stinging, burning, ocular redness, watery eyes, sensitivity to light, mild itch, blurry vision, and stringy mucus discharge.

Since there are many potential causes of dry eye, a person should contact a doctor if they have persistent dry eyes or their symptoms do not get any better. A doctor can check for other possible causes of the dryness and make a diagnosis.

A doctor will often ask about symptoms and examine the affected eye. According to the American Optometric Association , a doctor will likely check:

  • how the eye appears externally, including the structure of the lid and how a person is blinking
  • how the eyelids and cornea appear under a bright light and magnification

  • the quality of a persons tears

If a doctor suspects allergies, they may recommend an allergy test.

When Is It Eye Allergy When Is It Not

Other Conjunctivitis: When is it not an eye allergy? When the conjunctiva becomes red and inflamed, you may have pink eye. This is an infection, caused in most cases by a virus that may last up to a few weeks or, less frequently, its bacterial.

Discharge is often present, and the eyelids can be extremely swollen. Pink eye is frequently associated with a cold or respiratory infection. The bacterial kind often features a sticky, colored discharge, which can clamp the eyelids shut upon waking.

A more extreme form of allergic conjunctivitis is giant papillary conjunctivitis, or GPC, which affects those who wear contact lenses , since debris on the lens or rubbing can lead to irritation. Symptoms include tearing, mucus discharge, blurry vision, the sensation of a foreign body and difficulty tolerating contacts, and the answer is often to take a break from wearing lenses and use of medication.

Vernal Keratoconjunctivitis: This eye allergy is generally more severe than seasonal or perennial conjunctivitis. It peaks between April and August, tending to affect those more in warm, dry climates. Thickening/swelling of the conjunctiva, as well as raised bumps may occur. Again, this needs early therapeutic treatment by an eye-care practitioner.
