Introduction: What Is Conjunctivitis (Pink Eye)?
Conjunctivitis (Pink Eye) is one of the most common and contagious eye conditions worldwide. It occurs when the conjunctiva โ the thin, transparent membrane covering the white part of your eye and the inside of your eyelids โ becomes inflamed. This inflammation leads to redness, irritation, tearing, and sometimes thick discharge. While conjunctivitis can affect anyone, proper treatment and hygiene can prevent its spread and protect long-term eye health.
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).
๐น 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.
๐น Transmission: easily spreads through direct contact (hands, towels, cosmetics).
๐น Treatment: usually involves antibiotic eye drops or ointments, which clear the infection within 3โ7 days.
๐น Prevention: regular handwashing, avoiding sharing personal items, and maintaining proper eye hygiene.
