Conjunctivitis (Pink Eye): Symptoms, Treatment & Prevention

Introduction

Conjunctivitis, commonly known as Pink Eye, is one of the most frequent eye infections affecting both children and adults. It causes redness, irritation, discharge, and sometimes swelling of the eyes. While most cases are mild and resolve within a few days, some forms require proper medical attention and treatment.

At Pharmacy9, we provide reliable health information to help you understand symptoms, choose the right pink eye treatment, and prevent the spread of this contagious eye infection.

What is Conjunctivitis?

Conjunctivitis is the inflammation of the conjunctiva — the thin, transparent membrane that covers the white part of the eye and lines the inside of the eyelids. When this membrane becomes irritated or infected, it leads to eye redness, swelling, itching, and discharge.

It can affect one or both eyes and may spread easily depending on the cause.

Types of Conjunctivitis

Understanding the type of conjunctivitis is essential for choosing the best conjunctivitis treatment.

1. Viral Conjunctivitis

Viral conjunctivitis is the most common type. It is usually caused by viruses such as the common cold virus.

• Watery discharge

• Red, irritated eyes

• Highly contagious

• May spread from one eye to the other

This type typically clears up within 7–14 days without antibiotics.

2. Bacterial Conjunctivitis

Bacterial conjunctivitis is caused by bacteria and often produces thick, yellow or green eye discharge.

• Sticky eyelids, especially in the morning

• Swollen eyelids

• Moderate redness

• Requires antibiotic eye drops in many cases

3. Allergic Conjunctivitis

Allergic conjunctivitis occurs due to allergens such as pollen, dust, or pet dander.

• Severe itching

• Watery eyes

• Affects both eyes

• Not contagious

This form improves with antihistamines or allergy relief medications.

Pink Eye Symptoms

Recognizing pink eye symptoms early can help prevent complications and spreading.

Common symptoms include:

• Eye redness

• Burning sensation

• Gritty feeling in the eye

• Watery or thick eye discharge

• Crusting around eyelids

• Light sensitivity

• Swollen eyelids

If symptoms worsen or vision becomes blurry, seek medical advice immediately.

Causes of Conjunctivitis

The most common red eye causes include:

• Viral infections

• Bacterial infections

• Allergic reactions

• Contact lens misuse

• Exposure to smoke or chemicals

• Poor hygiene

Understanding the cause helps determine whether you need antibiotic drops or simple home care tips.

Is Conjunctivitis Contagious?

One of the most common questions is: Is conjunctivitis contagious?

• Viral conjunctivitis: Highly contagious

• Bacterial conjunctivitis: Contagious

• Allergic conjunctivitis: Not contagious

Pink eye spreads through direct contact, contaminated surfaces, towels, eye makeup, or touching infected eyes.

Conjunctivitis Treatment Options

Treatment depends on the type of infection.

1. Viral Pink Eye Treatment

There is no specific antiviral medication for most cases. Focus on eye infection relief through:

• Cold compress

• Artificial tears

• Good hygiene

• Avoiding contact lenses

Recovery usually takes 1–2 weeks.

2. Bacterial Pink Eye Treatment

Doctors may prescribe antibiotic eye drops or ointments.

• Complete the full course

• Avoid sharing towels

• Clean eye discharge gently

Improvement is often seen within 2–3 days after starting antibiotic drops.

3. Allergic Pink Eye Treatment

Treatment includes:

• Antihistamine eye drops

• Avoiding allergens

• Cold compress

• Over-the-counter allergy medication

How to Treat Conjunctivitis at Home Safely

If symptoms are mild, follow these home care tips:

• Wash hands frequently

• Avoid rubbing eyes

• Use clean tissues

• Wash pillowcases daily

• Stop wearing contact lenses

• Use separate towels

These steps help reduce the spread of contagious eye infection.

How Long Does Pink Eye Last?

Duration depends on the type:

• Viral conjunctivitis: 7–14 days

• Bacterial conjunctivitis: 3–7 days with treatment

• Allergic conjunctivitis: Until allergen exposure continues

If symptoms persist beyond two weeks, consult a healthcare provider.

Pink Eye vs Eye Allergy

Many people confuse pink eye vs eye allergy.

Feature	Viral/Bacterial	Allergic
Contagious	Yes	No
Itching	Mild	Severe
Discharge	Thick or watery	Watery
Affects both eyes	Sometimes	Usually

Knowing the difference ensures proper conjunctivitis treatment.

When to See a Doctor

Seek medical care if:

• Severe eye pain

• Blurred vision

• Light sensitivity

• Symptoms worsen

• Thick green discharge

• No improvement after 5 days

Children, newborns, and contact lens users should consult a doctor quickly.

Prevention Tips

Preventing conjunctivitis is simple with proper hygiene:

• Wash hands regularly

• Avoid touching eyes

• Disinfect surfaces

• Do not share cosmetics

• Replace old eye makeup

• Clean contact lenses properly

Practicing these habits reduces risk of eye infection.

Complications of Untreated Conjunctivitis

Though rare, untreated bacterial conjunctivitis may cause:

• Corneal infection

• Vision issues

• Chronic inflammation

Early pink eye treatment prevents complications.
