As parents, we always want our children to feel their best. So, when your child complains of itchy, red, or watery eyes, it’s natural to feel concerned. One common reason behind these symptoms is allergic conjunctivitis. While the term may sound complex, don’t worry — we’ll break it down in simple, easy-to-understand language.

In this guide by Dr. Mahesh Katre, we’ll explain what allergic conjunctivitis in children is, what causes it, and how you can help your little one feel better. Allergic conjunctivitis in children occurs when the eyes become inflamed due to allergens like pollen, dust mites, or pet dander. Understanding the symptoms and triggers can help you manage and alleviate discomfort for your child.

What Is Allergic Conjunctivitis?

Allergic conjunctivitis is an eye condition that happens when the eyes react to allergens — things that cause allergies. The word “conjunctivitis” means inflammation of the conjunctiva, which is the thin layer that covers the white part of the eye and the inside of the eyelids.

When your child’s eyes come in contact with something they are allergic to, the body reacts by releasing histamine, a chemical that causes redness, swelling, itching, and watering of the eyes.

It is not contagious like viral or bacterial conjunctivitis, so it doesn’t spread from one person to another.

Common Symptoms of Allergic Conjunctivitis in Children

The signs are usually easy to notice. Some of the most common symptoms include:

• Red or pink eyes

• Itchy eyes (your child may keep rubbing them)

• Watery eyes or teary discharge

• Puffy or swollen eyelids

• Burning sensation in the eyes

• Sensitivity to light (bright lights may bother your child)

• A feeling that there is something stuck in the eye

If your child has these symptoms in both eyes, and they happen around the same time every year or after contact with something specific (like a pet or pollen), it may be allergic conjunctivitis.

What Causes Allergic Conjunctivitis in Children?

There are many things that can trigger allergic conjunctivitis in children. These are called allergens. Here are some common ones:

1. Pollen (Seasonal Allergens)

Pollen comes from trees, grass, and weeds. It usually increases during spring, summer, or fall depending on the type of plants around you. Children who are allergic to pollen may develop symptoms during these seasons. This type is called seasonal allergic conjunctivitis.

2. Dust Mites

Dust mites are tiny creatures that live in household dust. They are too small to see, but they can cause big allergy problems for sensitive children. Dust mite allergies are common all year round and may get worse during the winter when kids spend more time indoors.

3. Pet Dander

Cats and dogs shed tiny flakes of skin called dander. When children are allergic to pet dander, their eyes may react every time they are around pets. The reaction can be mild or severe depending on the level of sensitivity.

4. Mold Spores

Mold is a type of fungus that grows in damp or humid areas like bathrooms, kitchens, or basements. Mold spores float in the air and can cause allergic conjunctivitis in sensitive children.

5. Smoke and Air Pollution

Smoke from cigarettes, fireplaces, or even air pollution can irritate the eyes and cause allergy-like symptoms in some children, especially if they already have allergies.

6. Chemical Irritants

Sometimes, allergic conjunctivitis is triggered by chemicals found in:

• Shampoos

• Soaps

• Detergents

• Chlorine in swimming pools

• Perfumes and sprays

These are more likely to cause irritant conjunctivitis, but if your child is allergic, even a small exposure can lead to symptoms.

Types of Allergic Conjunctivitis

There are two main types that affect children:

1. Seasonal Allergic Conjunctivitis (SAC)

This happens during certain times of the year when pollen levels are high. It usually affects both eyes and may come and go with the seasons.

2. Perennial Allergic Conjunctivitis (PAC)

This type occurs all year round and is often caused by indoor allergens like dust mites, mold, or pet dander.

Other less common but more severe types include:

• Vernal keratoconjunctivitis (VKC) – mostly affects boys in hot, dry climates

• Atopic keratoconjunctivitis (AKC) – linked with eczema and may continue into adulthood

If your child shows symptoms that are constant or severe, it’s important to consult an eye specialist.

How Is Allergic Conjunctivitis Diagnosed?

To find out if your child has allergic conjunctivitis, your doctor or eye specialist may:

• Ask about symptoms

• Do a physical examination of the eyes

• Ask if symptoms are seasonal or triggered by certain things

• Recommend an allergy test if needed to identify the specific allergen

At Dr. Mahesh Katre’s clinic, we make sure to carefully check your child’s symptoms and history to find the root cause of the allergy.

How to Treat Allergic Conjunctivitis in Children

The good news is that allergic conjunctivitis is treatable! Here are the most common treatment options:

1. Avoid the Allergen

The best way to prevent symptoms is to keep your child away from the allergen. While this may not always be possible, you can take steps like:

• Keeping windows closed during high pollen days

• Using air purifiers indoors

• Washing hands and face after outdoor play

• Bathing pets regularly (or keeping them out of bedrooms)

• Cleaning dusty areas and using dust-proof pillow covers

2. Cold Compresses

Applying a clean, cold washcloth to your child’s eyes can help reduce itching and swelling.

3. Artificial Tears (Eye Drops)

These are over-the-counter eye drops that help wash away allergens and soothe the eyes. They are safe and can be used a few times a day.

4. Antihistamine Eye Drops

These special eye drops block histamine, the chemical that causes allergy symptoms. They work fast to relieve itching and redness.

5. Oral Antihistamines

If the allergy also affects your child’s nose (sneezing, runny nose), your doctor may recommend oral allergy medicine. These are usually safe for kids but should be given under a doctor’s advice.

6. Prescription Medicines

For more serious cases, your doctor may prescribe steroid eye drops or stronger medications. These should only be used as directed by an eye specialist.

At Dr. Mahesh Katre’s clinic, we believe in personalized care and only recommend medication when truly needed, focusing on the safest and most effective treatment for your child.

Can Allergic Conjunctivitis Go Away on Its Own?

Sometimes, mild allergic conjunctivitis goes away when the allergen is removed. For example, if your child’s eyes react after visiting a house with cats, the symptoms may improve after you return home.

However, if the exposure continues (like living in a dusty house or during pollen season), the symptoms may stick around or keep coming back.

What Can Parents Do to Help?

Here are some simple and helpful tips for parents:

• Don’t let your child rub their eyes – it can make things worse

• Use clean tissues or cloths to wipe tears

• Keep fingernails short and clean to avoid eye injuries

• Wash pillowcases and sheets regularly

• Limit outdoor play during high pollen times (like early morning)

• Use sunglasses to protect eyes from pollen and sun

• Keep your home clean and dry to reduce dust and mold

• Visit an eye doctor if symptoms don’t improve

When Should You See a Doctor?

Always contact your child’s doctor or eye specialist if:

• Symptoms last more than a few days

• The eyes become very red or swollen

• There is thick or yellow discharge (could be infection)

• Your child has trouble seeing or complains of eye pain

• Over-the-counter medicines don’t help

Early treatment prevents discomfort and avoids complications.
