Pink Eye (Conjunctivitis)

Quick diagnosis and treatment for pink eye

Pink eye is uncomfortable and often contagious, but highly treatable. We can accurately diagnose which type of conjunctivitis you have and provide fast relief with the right treatment plan.

Understanding

What is pink eye (conjunctivitis)?

Pink eye is inflammation of the conjunctiva—the clear membrane covering the white of your eye and inner eyelid. This inflammation causes blood vessels to become enlarged and prominent, giving the eye its characteristic pink or red appearance.

Pink eye can develop suddenly and range from mildly uncomfortable to seriously painful. While some types resolve on their own, others require treatment to prevent complications and reduce contagiousness. The good news: we can quickly identify which type you have and start appropriate treatment.

It's a common condition

Pink eye affects millions of people each year, particularly children in schools and classrooms. Early diagnosis and proper treatment ensure faster recovery and prevent spread to others.

Classification

Types of conjunctivitis

Pink eye isn’t one-size-fits-all. Identifying the type is crucial because each has different causes, symptoms, contagiousness levels, and treatments.

Viral Conjunctivitis

Most common type. Usually caused by adenoviruses or cold viruses. Highly contagious and spreads through contact with eye secretions. Typically characterized by watery discharge and resolves on its own within 1-2 weeks.

Bacterial Conjunctivitis

Requires treatment. Caused by bacterial infection. Features thick yellow-green discharge; eyelids may stick together. Contagious but responds quickly to antibiotic eye drops. Treatment is essential.

Allergic Conjunctivitis

Not contagious. Triggered by allergens like pollen, pet dander, or dust mites. Intense itching is the key symptom. Affects both eyes and responds well to allergy medications and allergen avoidance.

Irritant Conjunctivitis

Not contagious. Caused by chemical exposure, smoke, chlorine, or foreign objects in the eye. Improves quickly once the irritant is removed and the eye is rinsed thoroughly

⚠️ Contagiousness matters for your family

Viral and bacterial pink eye are highly contagious and can spread to family members, classmates, and coworkers. Allergic and irritant types are not contagious. Proper diagnosis helps you protect others from infection.

Symptoms

How to recognize different types of pink eye

Symptoms vary depending on the cause. Identifying your symptoms helps us diagnose the type and recommend appropriate treatment.

Redness

Blood vessels in the conjunctiva dilate, making the eye(s) noticeably red or pink.

Watery Discharge

Usually indicates viral conjunctivitis; eyes water excessively and the discharge is clear or slightly cloudy.

Thick Yellow-Green Discharge

Classic sign of bacterial conjunctivitis; may cause eyelids to stick together after sleep.

Intense Itching

Most common symptom of allergic conjunctivitis; watery eyes and swollen eyelids may also occur.

Gritty Feeling

Sensation of something in the eye; common with viral and bacterial types.

Mild Discomfort

Irritant conjunctivitis typically causes mild to moderate discomfort that improves quickly with rinsing.

Swollen Eyelids

Eyelids may puff up or swell, especially noticeable in the morning with bacterial or allergic types.

Light Sensitivity

Bright light may feel uncomfortable; more common with viral or bacterial types.

Causes

What causes pink eye?

Understanding the cause helps determine contagiousness and the best treatment approach. Some causes are preventable; others are harder to avoid.

Respiratory Infections

Viral conjunctivitis often accompanies colds and respiratory infections caused by adenoviruses.

Bacterial Exposure

Contact with infected individuals, contaminated surfaces, or poor hand hygiene spreads bacterial pink eye.

Allergen Exposure

Pollen, pet dander, dust mites, mold, and other allergens trigger allergic conjunctivitis year-round or seasonally.

Chemical Irritants

Chlorine, smoke, fumes, perfume, or cosmetics can irritate the conjunctiva and cause inflammation.

Contact Lens Misuse

Improper lens cleaning, wearing lenses too long, or using contaminated solutions increases bacterial or fungal infection risk.

Neonatal Exposure

Newborns can develop conjunctivitis from bacteria or viruses encountered during birth; requires immediate medical attention.

School notification requirements

If your child has bacterial or viral pink eye, schools typically require notification and may restrict attendance for 24 hours after antibiotic treatment begins or until symptoms improve significantly.

Diagnosis

How we diagnose pink eye

Accurate diagnosis requires more than just looking at the redness. We perform thorough testing to identify the exact cause and guide appropriate treatment.

Medical History Review

We ask about symptom onset, exposure to illness or allergens, and any recent activities that could cause irritation.

Visual Examination

We examine your eye under magnification using a slit-lamp to assess redness, discharge, and eyelid involvement.

Symptom Assessment

We identify key symptoms—watery vs. thick discharge, itching, severity—that point to the specific type.

Discharge Evaluation

The type and color of discharge (clear, watery, yellow-green) helps us differentiate between viral and bacterial causes.

Laboratory Testing

For unclear cases, we may culture the discharge to identify bacterial pathogens and ensure appropriate antibiotic selection.

Allergy Assessment

If allergic conjunctivitis is suspected, we discuss allergen exposure and seasonal patterns.

Solutions

Pink eye treatment based on type

Treatment varies significantly depending on the cause. Here’s what works for each type.

Viral Conjunctivitis Treatment

There’s no antiviral medication, so treatment focuses on comfort while your body fights the infection. Most resolve within 1-2 weeks.

Cold Compresses

Apply cool, damp cloths to reduce discomfort and swelling throughout the day.

Artificial Tears

Over-the-counter lubricating drops soothe irritation and provide comfort during healing.

Strict Hygiene

Frequent hand washing and avoiding eye touching are essential to prevent spread to others.

Rest & Time

Allow your immune system to clear the virus. Most people recover completely within 1-2 weeks.

Bacterial Conjunctivitis Treatment

Antibiotics are essential to clear the infection quickly and prevent complications. Treatment typically takes 5-7 days.

Antibiotic Eye Drops

Prescribed drops eliminate bacteria and relieve symptoms. Use as directed for the full course even if symptoms improve.

Antibiotic Ointment

Thick ointment formulations provide longer-lasting antibiotic coverage, especially useful at bedtime.

Eyelid Cleaning

Gently clean crusted discharge from the eyelids with warm water and a clean cloth, especially after sleep.

Contagion Prevention

Avoid touching eyes, wash hands frequently, and don't share towels, cosmetics, or eye care items.

Allergic Conjunctivitis Treatment

Focus on avoiding triggers and managing the allergic response. Not contagious, so no isolation needed.

Antihistamine Drops

Over-the-counter or prescription drops reduce itching and redness by blocking allergic reactions.

Mast Cell Stabilizers

These drops prevent histamine release, offering prevention and relief for allergy-prone individuals.

Allergen Avoidance

Identify and minimize exposure to triggers: close windows during pollen season, use air purifiers, avoid pets if allergic.

Cool Compresses

Cold compresses soothe itching and reduce swelling. Refrigerate compresses for added relief.

Irritant Conjunctivitis Treatment

Immediate removal of the irritant is key. Most cases resolve quickly once the eye is cleared.

Rinse Thoroughly

Flush the eye with clean water or sterile saline solution to remove the irritant immediately.

Avoid Re-Exposure

Identify and eliminate the source: remove contacts if irritated, avoid smoke, stay away from chemicals.

Artificial Tears

Lubricating drops provide comfort and help wash away any remaining irritant particles.

Time & Rest

Most irritant conjunctivitis resolves within hours to days once the irritant is removed and rinsed away.

When to seek emergency care

Contact us immediately if you experience significant vision loss, severe pain, chemical exposure to the eye, or symptoms that don’t improve within 24-48 hours. These may indicate serious complications requiring urgent evaluation.

Prevention

How to prevent pink eye

Prevention varies by type, but good hygiene is universally important. Here are evidence-based strategies to reduce your risk.

Wash Your Hands

Frequent, thorough hand washing is the #1 way to prevent viral and bacterial transmission.

Don't Touch Your Eyes

Avoid touching or rubbing eyes, especially in public or after touching shared surfaces.

Don't Share Items

Never share eye makeup, contacts, contact lens solutions, eye drops, towels, or eye care products.

Clean Contact Lenses

Follow proper lens care: clean with solution daily, don't use saliva, replace containers regularly.

Keep Makeup Fresh

Replace eye makeup every 3 months, discard old products, and never share cosmetics with others.

Allergen Management

For allergies: keep windows closed during pollen season, use air filters, and minimize pet contact if allergic.

Keep kids home to prevent spread

If your child has viral or bacterial pink eye, keep them home from school for at least 24 hours after starting treatment or until symptoms significantly improve. This protects classmates and teachers from infection.
