Allergies are one of the most common medical conditions in kids. Seasonal allergies (or hay fever) affect more than 7% of children in the United States. If your child has itchy, red, or watery eyes, your child might have allergies.

Eye allergies in kids are often caused by environmental allergens, like pollen or mold. Kids often rub their eyes when they’re uncomfortable, which exacerbates allergy symptoms.

Eye allergies (allergic conjunctivitis) occur when allergens get into the eye. Common allergens are pollen, mold, dust, and pet dander. Kids who have hay fever (allergic rhinitis) may experience itchy, watery, and red eyes.

When allergens get into the eyes, the body releases chemicals, including histamines, that trigger inflammation. The response will cause the area around the eye to become red and inflamed.

The irritation mostly occurs in the tissue that surrounds the eyeball and forms the inside of the eyelids (the conjunctiva). A child's eyes might also water as they try to flush out the allergens. 

If your child has puffy, red eyes you may wonder if they have allergies or conjunctivitis, an infection of the conjunctiva, also called pink eye. There are a couple of differences between the conditions that can help you figure out which one is causing your child's symptoms.

Young children may not be able to tell you about their symptoms, but their behavior may suggest that they are experiencing an allergic reaction. For example, they will rub their eyes or cry.

Even if your child cannot tell you what is wrong, many of the symptoms of eye allergies are easy to spot.

Common symptoms of eye allergies in kids include:

Your child might also have other symptoms of hay fever, such as sneezing or coughing.

If your child has never experienced eye allergies before, talk with their pediatrician about their symptoms. Eye allergies are diagnosed based on your child's symptoms. Allergy tests are rarely needed.

After eye allergies are diagnosed, your child's doctor will recommend management. Follow-up care will only be necessary if the treatment is not working.

In most cases, eye allergies are treated using over-the-counter (OTC) drugs and lifestyle adjustments to limit exposure to allergens.

For severe allergies, your child's doctor might recommend prescription medications or an allergy shot.

The best way to control eye allergy symptoms in kids is prevention. If your child has a history of eye allergies, start giving them a daily OTC allergy medication before the start of the season in which their allergies usually occur (often in the spring).

When taken daily, medications like Claritin (loratadine) and Zyrtec (cetirizine) can keep hay fever and eye allergy symptoms at bay.

If your child has breakthrough symptoms (symptoms that appear while they're taking medications), there are some other things that you can try.

Other ways to help prevent eye allergies and treat breakthrough symptoms include:

To prevent eye allergies in kids, minimize their exposure to allergens. Ways that you can reduce exposure to allergy triggers include:

In most cases, eye allergies are irritating but harmless. However, there are some situations in which you should speak to your child's doctor, including:

Eye allergies are common in kids. Itchy, watery, red eyes can be a sign of exposure to allergens, environmental irritants, or infections like conjunctivitis. If you are not sure what is causing your child's eye symptoms, talk to a doctor.

Usually, your child's doctor can diagnose eye allergies just by their symptoms. They can provide you with treatment recommendations. Most of the time, OTC medications and lifestyle adjustments are enough to manage your child's allergies. If the symptoms are severe, your doctor might suggest a prescription medication.

Eye allergies can be uncomfortable for everyone, including children. The best way to help your child stay comfortable during allergy season is by getting ahead of their symptoms by giving them an OTC allergy medication daily and taking steps to limit exposure to allergy triggers (such as washing their face and hands daily).

If symptoms don't go away or other signs appear, a visit to the pediatrician is in order to pinpoint the cause of the eye irritation and to get your child relief.

Eye allergies generally do not produce the pus and crusts that are the primary symptoms of pink eye (conjunctivitis). Eye allergies usually affect both eyes at the same time, whereas conjunctivitis often starts in one eye before moving to the other.

If your child has allergies, symptoms such as sneezing, coughing, or stuffiness may also be present.

If you're in doubt, reach out to your child's doctor. While allergies can usually be managed at home, conjunctivitis is very contagious and needs to be treated by a healthcare provider.

The symptoms of eye allergies last as long as your child's eyes are exposed to allergens. For pollen allergies (hay fever), that can be four to eight weeks. During pollen season, it may be helpful to treat your child with daily allergy medication to help minimize their symptoms. 

Applying a cool washcloth to your child's eyes and flushing their eyes with a small amount of water can help reduce irritation and itching.

If your child has a history of allergies, the best way to get ahead of their symptoms is through prevention. This can include giving them daily OTC allergy medication and taking steps to reduce exposure to allergens at home and when they are outside.
