Pink eye also known as conjunctivitis is one of the most common eye problems people experience worldwide. Although it’s usually mild, it can still cause significant discomfort and spread rapidly if not handled properly. Whether you’re caring for a child, working in a public environment, or simply looking to protect your own eye health, understanding pink eye is essential. This guide covers everything you need to know, from what causes it to the best ways to treat and prevent it.
What Is Pink Eye?
Pink eye refers to the inflammation of the conjunctiva, the transparent layer that covers the white part of your eye and lines the inner surface of the eyelids. When this layer becomes irritated or infected, the tiny blood vessels inside it enlarge, giving the eye a reddish or “pink” appearance.
There are three major types of conjunctivitis, each with its own cause and treatment needs:
1. Viral Conjunctivitis
-
The most frequent form
-
Typically linked to respiratory infections like the cold or flu
-
Highly contagious and can spread in crowded environments
2. Bacterial Conjunctivitis
-
Caused by bacteria such as Staphylococcus or Streptococcus
-
Produces thick, sticky discharge
-
May require antibiotic drops or ointment
3. Allergic Conjunctivitis
-
Triggered by allergens like pollen, pet dander, dust mites, or mold
-
Not contagious
-
Often accompanied by sneezing or seasonal allergy symptoms
How Does Pink Eye Spread?
The transmission of pink eye depends on the underlying cause:
Viral Spread
-
Coughing, sneezing, or touching contaminated surfaces
-
Sharing pillows, towels, makeup, or electronics
Bacterial Spread
-
Direct contact with infected hands or objects
-
Sharing personal hygiene or cosmetic items
Allergic Irritation
-
Caused by environmental allergens
-
Cannot be transmitted from person to person
Risk factors that increase your chances of getting pink eye include:
-
Frequent eye touching
-
Improper contact lens hygiene
-
Sharing makeup or towels
-
Weakened immune system

Working in schools, hospitals, or daycare settings
Common Symptoms of Pink Eye
While symptoms vary depending on the type, most people experience at least a few of the following:
-
Red or pink appearance in one or both eyes

Watery or mucous-like discharge

Itchy, gritty, or burning sensation

Crusty eyelids, especially after waking
