Eye Allergies: Causes, Symptoms and Treatment

The sensation that something is in your eye is the most annoying thing. However, allergies may be to blame if your eyes are red and irritated and you cannot see anything. Although they can happen independently, nasal allergy symptoms like sneezing, sniffling, or a stuffy nose frequently accompany them.

Eye allergies, often known as "allergic conjunctivitis," are typical illnesses affecting the eyes. The conjunctiva is the tissue that borders the outside of the eyeball and the inside of the eyelid. Your eyelid and eyeball remain moist thanks to this tissue.

When this tissue swells up, allergic conjunctivitis develops. When you have eye allergies, you typically experience irritation and redness in both eyes rather than just one.

What signs indicate an Eye Allergy?

Allergens, as opposed to germs or viruses, cause eye allergies, a specific kind of conjunctivitis. The conjunctiva is the transparent tissue that lines the inside of your eyelid and covers your eyeball. Eye allergies are not contagious, in contrast to other types of conjunctivitis.

Common Eye Allergy Signs and Symptoms

All of the eye's visible components are susceptible to allergies. Typical signs include:

Redness, burning, or itching
enlarged eyelids
clogged tear ducts
sensitivity to light
Eye allergies are typically only a small part of a larger physiological response to an allergen, including headache, sore throat, coughing, itchy or runny nose, and other symptoms.

What causes allergies in the eyes?

When the body's immune system reacts to an allergen that is often harmless, it is said to have an allergy. A group of cells in your eye known as mast cells release histamine and other chemicals to fend off an allergen when it comes into contact with your eye. Due to this reaction, your eyes turn red, itch, and start to water.

Many eye allergies are brought on by allergens in the air, both inside and outside. Among these allergies are:

Seasonal and perennial allergic conjunctivitis

The most typical type of ocular allergy is seasonal allergic conjunctivitis (SAC). Patients may develop symptoms in the spring, summer, or fall, depending on the type of plant pollen in the air. Common signs include:

Itching
Redness
Burning
Clear, watery discharge

Chronic under-eye dark circles, or "allergic shiners," are a potential symptom of SAC. Bright lights may cause irritability and swollen eyelids. Patients with severe itching may regularly rub their eyes, aggravating their symptoms and raising the risk of infection. Runny nose, sneezing, and nasal congestion linked to hay fever and other seasonal allergies sometimes go hand in hand with SAC symptoms.

As its name suggests, perennial allergic conjunctivitis (PAC) happens all year round. The symptoms are similar to those with SAC but typically appear milder. Rather than being brought on by pollen, they are brought on by reactions to dust mites, mould, pet dander, or other household allergens.

Vernal keratoconjunctivitis

SAC or PAC are less severe cases of ocular allergies than vernal keratoconjunctivitis. Seasonal changes may make the symptoms worse. However, it can happen all year. About 75% of patients also have eczema or asthma; it mostly affects boys and young men. These signs include:

Itching
significant tears, thick mucus production, and the sensation of a foreign body being in one's eye.
Photophobia is a dislike of light.

Vernal keratoconjunctivitis can compromise vision if untreated.

Atopic keratoconjunctivitis

Older patients, especially men with a history of allergic dermatitis, are most commonly impacted by this allergy. Atopic keratoconjunctivitis can have year-round symptoms that are comparable to vernal keratoconjunctivitis:

intense itch
Burning Redness
significant mucus production that may cause the eyelids to stay together after sleeping

Atopic keratoconjunctivitis can scar the cornea and its delicate membrane if not treated.

Contact allergic conjunctivitis

It may happen due to contact lens discomfort or tear protein adhesion to the lens surface. These signs include:

Redness Itching
mucous expulsion
Uncomfortable lenses

Giant papillary conjunctivitis

Giant papillary conjunctivitis, a severe case of contact allergic conjunctivitis where individual fluid sacs, or bumps, develop in the upper lining of the inner eyelid, is connected to the use of contact lenses. These signs include:

Itching Puffiness
Tearing
discharge of mucous
fuzzy vision
contact lenses are not tolerated well
the feeling of a foreign body

What Is the Treatment for Eye Allergies?

Avoiding or limiting contact with the chemical causing the problem is the key to treating eye allergies. But you must be aware of what to avoid. An allergist may do a skin or blood test to help pinpoint the allergen(s).

Avoiding allergens

If you have a pollen allergy, stay indoors as much as possible during peak pollen seasons. Early morning and midday typically see the highest pollen concentrations. When you are outside, wearing sunglasses or eyewear might help keep pollen out of your eyes. Additionally, avoid being outside when the wind is blowing pollen.
Use air conditioning inside and outside your home and automobile, and keep the windows closed. It will lessen the pollen and other allergens you are exposed to indoors. Avoid using window fans as they bring allergies and pollen indoors. Keep your air conditioners clean to prevent the circulation of allergens inside.
If mould triggers your allergies, be aware that moulds can grow in environments with high humidity. Try to maintain a humidity level of between 30 and 50 per cent in your home. Regularly clean damp spaces, including basements, bathrooms, and kitchens. Consider using a dehumidifier in areas that are very damp or moist, such as a basement.
Try to keep dust mites away from your skin if your allergic conjunctivitis is brought on by household dust. Focus particularly on your bedroom. Use covers that minimise allergens for your pillows and beds. Use hot water at least 130 degrees Fahrenheit to wash your bedding frequently.
When cleaning floors, use a damp mop or rag instead of a dry dust mop or broom to trap the allergens.
Try to keep animals out of the house as much as you can if you have allergies to pets. To sleep in a room free of allergens, keeping pets out of your bedroom is especially crucial. Instead of carpeting, which collects pet dander, consider hardwood or tile floors. After petting a pet, always wash your hands. Also, wash any clothing you may have worn around animals.

Last but not least, never massage your eyes since this irritates them.

OTC eyedrops and medications

Nonprescription (over-the-counter or OTC) eyedrops and oral medicines are frequently utilised to relieve some symptoms temporarily. They might not eliminate every symptom, and extended use of some over-the-counter eyedrops might make your situation worse.

Artificial tears: Artificial tears can temporarily remove irritants from the eye and moisturise dry, irritated eyes, which frequently experience dryness. These drops are secure and may be applied as often as required. They can be chilled to offer further calm and comfort.
Decongestants: By constricting the blood vessels in the eye, over-the-counter decongestant eyedrops lessen the redness brought on by allergies. They are available without an OTC antihistamine, which offers extra relief from itching, or with an OTC antihistamine and a decongestant. (Note: People with glaucoma shouldn't use these.) the drops must be used frequently (four to six times a day) due to their weakness. Use of these over-the-counter decongestant eyedrops is limited to two to three days. Long-term use can lead to a swelling and redness "rebound effect" that may persist even after the drop use is stopped. If you have used decongestant nasal sprays for over three days and noticed that your nose has worsened, you may be familiar with this.
Oral antihistamines: Although oral antihistamines may relieve the irritation from eye allergies, they may also worsen the condition by causing dry eyes and other side effects. Over-the-counter versions of these drugs can also have negative side effects, including drowsiness, excitability, dizziness, or impaired coordination.

Eyedrops and medicines on prescription

To treat eye allergies, prescription eyedrops and oral medicines are also employed. The prescribed drops target the symptoms of ocular allergies and offer both short-term and long-term treatment. For skilled treatment and relief, consult an allergist.

Eyedrops containing antihistamines can lessen the irritation, redness, and swelling brought on by allergies in the eyes. Although they offer immediate relief, some of these drops must be administered four times each day, and the impact may only last a few hours.
Mast cell stabiliser eyedrops: These stop histamine and other compounds that cause allergy symptoms from being released into the body. The drops must be applied before exposure to an allergen for the itching to stop.
Eyedrops with an antihistamine and a mast cell stabiliser: Some of the most recent eyedrops for treating and preventing eye allergies contain both an antihistamine and a mast cell stabiliser. They are applied twice daily and offer immediate and long-lasting relief from burning, itching, and redness.
Nonsteroidal anti-inflammatory medications (NSAIDs) can be found in eyedrop form to treat itching. These drops must be administered four times daily and may hurt or burn when applied.
Allergy shots: Itching, redness, and swelling are some of the chronic, severe symptoms of ocular allergies that can be treated with corticosteroid eyedrops. Steroid therapy that lasts more than two weeks should only be administered under the direction of an ophthalmologist because it increases the risk of infection, glaucoma, and cataracts.
Oral antihistamines that don't sedate: Prescription antihistamines may be only marginally useful in reducing the itching brought on by eye allergies. Although these drugs do not have the same sedating side effects as over-the-counter antihistamines, they can aggravate symptoms and produce dry eyes.
Shots for allergies (immunotherapy): Allergy shots increase a person's tolerance for what makes them sick. Tiny dosages of the allergen are injected over time in progressively higher doses. The full benefits of the treatment take several months to manifest, and you might still need to take drugs to manage your symptoms.

Kids with allergies to the eyes

Both over-the-counter and prescription eyedrops and medications can be used to treat children. You can use artificial tears at any age, and they are harmless. Children 3 and older can take some eyedrops, such as antihistamines and mast cell stabilisers. The doctor for your child should be consulted before beginning any treatment.
