Pink Eye (Conjunctivitis): Symptoms, Causes, Treatment, and When to See a Doctor
By Doctors On Demand, South Africa
What Is Pink Eye?
Pink eye, medically known as conjunctivitis, is a common eye condition that causes inflammation of the conjunctiva—the lining of the eye and the inside of the eyelids.
Conjunctivitis can affect one or both eyes and is often characterised by redness, irritation and discharge from the eye. While many cases are mild and self-limiting, some forms of conjunctivitis require medical treatment.
Common Symptoms of Pink Eye
Symptoms can vary depending on the cause but often include:
- Red or pink appearance of the eye
- Itchy eyes
- Watery eyes
- Burning or gritty sensation
- Swollen eyelids
- Eye discharge
- Crusting around the eyelids, especially after sleep
- Increased sensitivity to light
Symptoms may begin in one eye and spread to the other.
What Causes Conjunctivitis?
There are several different types of conjunctivitis, each with its own cause.
Viral Conjunctivitis
Viral conjunctivitis is the most common form of pink eye. It often develops alongside an upper respiratory tract infection.
Symptoms typically include:
- Redness commonly affecting both eyes
- Watery discharge
- Mild irritation
These infections are contagious. Most viral infections improve without specific treatment within one to two weeks.
Bacterial Conjunctivitis
Bacterial conjunctivitis occurs when bacteria cause an infection of the eye.
Common signs include:
- Thick yellow, green or white discharge
- Eyelids stuck together upon waking
- Crusting around the affected eye
- Redness and irritation
- Possible swelling
Bacterial conjunctivitis is contagious and may require prescription antibiotic eye drops or ointment.
Allergic Conjunctivitis
Allergic conjunctivitis occurs when the eyes react to allergens such as:
- Pollen
- Dust mites
- Pet dander
- Mould spores
Typical symptoms include:
- Intense itching
- Watery eyes
- Redness
- Sneezing or nasal allergy symptoms
Unlike viral and bacterial conjunctivitis, allergic conjunctivitis is not contagious.
Is Pink Eye Contagious?
Some forms of conjunctivitis are highly contagious.
Contagious Types
- Viral conjunctivitis
- Bacterial conjunctivitis
Non-Contagious Types
- Allergic conjunctivitis
- Irritant-related conjunctivitis
Conjunctivitis can spread through direct contact, shared towels, contaminated hands, makeup or eye-care products.
How Is Pink Eye Treated?
Treatment depends on the underlying cause.
Viral Conjunctivitis Treatment
Most viral cases improve with supportive care, including:
- Good hygiene practices
- Avoiding contact lens use during infection
- Avoidance of eye makeup during active infection
- Good hand hygiene
Bacterial Conjunctivitis Treatment
A healthcare provider may prescribe antibiotic eye drops or ointment if a bacterial infection is suspected.
Allergic Conjunctivitis Treatment
Treatment may include:
- Antihistamine eye drops
- Oral antihistamines
- Avoiding known allergy triggers
- Artificial tears to soothe irritation
How Long Does Pink Eye Last?
Recovery time depends on the cause.
- Viral conjunctivitis: Usually 1–2 weeks
- Bacterial conjunctivitis: Often improves within a few days of treatment
- Allergic conjunctivitis: Symptoms may persist while allergen exposure continues
If symptoms worsen or do not improve, medical evaluation is recommended.
Preventing the Spread of Conjunctivitis
Good hygiene is essential to prevent spreading infection.
Helpful precautions include:
- Washing hands frequently
- Avoiding touching or rubbing your eyes
- Not sharing towels, face cloths or pillows
- Replacing eye makeup after infection
- Cleaning contact lenses as directed
- Staying home from work or school if advised by a healthcare professional
When Should You See a Doctor?
Medical assessment is recommended if you experience:
- Severe eye pain
- Significant swelling
- Blurred or reduced vision
- Sensitivity to light
- Symptoms that worsen rapidly
- Thick or persistent discharge
- Symptoms that do not improve after several days
- Contact lens-related eye infections
Prompt treatment can help prevent complications and ensure the correct diagnosis.

Frequently Asked Questions
Can pink eye go away on its own?
Yes. Viral conjunctivitis often resolves without specific treatment, although symptoms can persist for several days to weeks.
Is conjunctivitis serious?
Most cases are mild but severe pain, vision changes, or significant swelling require urgent medical attention.
Can I wear contact lenses if I have pink eye?
No. Contact lenses should generally be avoided until symptoms have completely resolved and a healthcare professional advises it is safe to resume use.
How can I tell if my pink eye is bacterial or viral?
It can be difficult to distinguish between the two without medical assessment. Bacterial infections often produce thicker discharge, while viral infections typically cause watery eyes.
