Pink Eye vs. Allergies: Which Is It?

If your eyes are red, itchy, or watery, it can be hard to know what’s behind the irritation. Is it pink eye (medically referred to as conjunctivitis) or just eye allergies?

While these conditions share some symptoms, their root causes, treatments, and levels of concern/contagiousness are very different.

Let’s explore the differences between pink eye and eye allergies so that you’ll know when to wait it out, when to treat at home, and when to see a doctor.

What Is Pink Eye?

Pink eye, also called conjunctivitis, is an inflammation of the conjunctiva, or the thin, transparent lining that covers the white of your eye and the inside of your eyelid.

Types of Pink Eye

There are a few reasons your conjunctiva can become inflamed, meaning there are a few types of pink eye you can develop:

• Viral conjunctivitis: Viral conjunctivitis is caused by viruses like adenovirus, which is more frequently associated with the common cold, as well as viruses like herpes simplex, varicella-zoster, and measles. Viral pink eye is highly contagious.
• Bacterial conjunctivitis: Bacterial conjunctivitis is caused by bacteria like Staphylococcus, the same one that causes staph infections, or Streptococcus, the same one that causes strep throat. Bacterial pink eye is also pretty contagious.
• Allergic conjunctivitis: Allergic conjunctivitis, also known as eye allergies, occurs when the immune system encounters a triggering allergen like pollen, mold, or pet dander and causes the conjunctiva to become inflamed. Allergic conjunctivitis is not contagious.

What Are Eye Allergies?

Eye allergies (also called allergic conjunctivitis) occur when your immune system overreacts to specific allergens in your environment. The most common culprits for eye allergies include:

• Pollen (seasonal allergies)
• Dust mites
• Pet dander
• Mold spores
• Smoke or chemical irritants

Unlike pink eye, eye allergies are not contagious and often occur alongside other allergy symptoms like excessive sneezing or nasal congestion.

Pink Eye vs. Allergies: Key Differences

Here’s how to tell the two apart:

When It’s Likely Pink Eye

You may have pink eye if you notice:

• Redness or inflammation starting in one eye that spreads to the other.
• Thick yellow or green discharge that causes your eyelids to stick together.
• Pink eye symptoms accompanied by a cold or respiratory infection.
• Eye pain or sensitivity to light.

Viral and bacterial conjunctivitis are both contagious, so avoid sharing towels, pillows, or makeup, and wash your hands frequently.

When It’s Likely Eye Allergies

You may have eye allergies if you notice:

• Both eyes become red and itchy quickly and at the same time.
• Symptoms appear seasonally (spring, fall) or after exposure to pets, dust, or pollen.
• Your eyes become red while you also suffer from excessive sneezing, a runny nose, or nasal congestion.
• Relief comes with allergy medications or by avoiding triggers.

Eye allergies are uncomfortable but not dangerous or contagious.

Treatment Options

Pink Eye Treatment

• Viral conjunctivitis: Usually clears on its own in 1–2 weeks. Use warm compresses and artificial tears for relief.
• Bacterial conjunctivitis: Requires prescription antibiotic eye drops or ointments from a doctor.

Seek medical care if you experience severe pain, vision changes, or symptoms that worsen instead of improve.

Eye Allergy Treatment

• Avoid triggers: Stay indoors during high pollen counts, use air filters, and wash your bedding frequently.
• Over-the-counter eye drops: Use artificial tears to help rinse allergens from your eyes.
• Antihistamines: Use oral medications or antihistamine eye drops to reduce itching and redness.
• Prescription medications: For chronic allergies, your doctor may recommend stronger eye drops or immunotherapy (allergy shots).

How to Prevent Pink Eye and Allergies

Preventing Pink Eye

• Wash your hands regularly and avoid touching your eyes.
• Don’t share makeup, towels, or contact lenses.
• Wash pillowcases frequently.
• Disinfect surfaces if someone in your home has pink eye.

Preventing Eye Allergies

• Check daily pollen counts and limit outdoor activities during peak levels.
• Use HEPA filters in your home.
• Shower and change clothes after being outside.
• Keep windows closed during allergy season.
• Follow your allergist’s long-term care plan.

When to See a Doctor

You should see an eye doctor or allergist if:

• Your symptoms are severe or persistent.
• You have significant eye pain or blurred vision.
• Discharge is thick, yellow, or green.
• Over-the-counter allergy medications don’t provide relief.
• You suspect bacterial pink eye.

Prompt treatment can prevent further discomfort and complications, especially with bacterial conjunctivitis.
