Introduction: What Is Conjunctivitis (Pink Eye)?
Conjunctivitis, commonly known as pink eye, is one of the most widespread eye conditions worldwide. It occurs when the conjunctiva—the thin, transparent layer of tissue covering the white part of your eye and the inside of your eyelids—becomes inflamed. This inflammation leads to redness, irritation, tearing, and sometimes discharge.
Pink eye affects millions of people each year, from children in daycare to adults in the workplace. While many cases are mild, some can cause serious discomfort and require medical attention. The good news is that conjunctivitis is usually treatable and preventable with proper eye care practices.
Types of Conjunctivitis
Understanding the type of conjunctivitis is crucial because the cause determines the treatment.
1. Viral Conjunctivitis
- Cause: Viruses such as adenovirus.
- Symptoms: Watery discharge, redness, light sensitivity, usually starts in one eye and spreads to the other.
- Contagious? Highly contagious.
2. Bacterial Conjunctivitis
Bacterial Conjunctivitis is an inflammation of the conjunctiva caused by a bacterial infection (most commonly Staphylococcus aureus, Streptococcus pneumoniae, or Haemophilus influenzae).
🔹 Symptoms:
- redness and swelling of the eye,
- thick yellow-green discharge, often causing eyelids to stick together in the morning,
- burning sensation and discomfort,
- tearing and blurred vision.
🔹 Transmission: easily spreads through direct contact (hands, towels, cosmetics).
🔹 Treatment: usually involves antibiotic eye drops or ointments, which clear the infection within 3–7 days.
🔹 Prevention: regular handwashing, avoiding sharing personal items, and maintaining proper eye hygiene.
