Causes of Conjunctivitis
The causes of conjunctivitis mainly depend on the type of conjunctivitis that has infected you:
- Viral conjunctivitis: Viral infections like the common cold are one of the most common causes of conjunctivitis. This type is highly contagious.
- Bacterial conjunctivitis: As the name suggests, this type of conjunctivitis is caused by bacteria like Staphylococcus aureus, Streptococcus pneumonia, or Haemophilus influenza. It can lead to discharge (pus) from the eyes.
- Allergic conjunctivitis: It affects both eyes and is usually caused by allergens like pollen, dust mites, or certain medication. It usually leads to itching, tearing, and swelling in the eyes.
- Conjunctivitis caused by irritants: Exposure to irritants such as smoke, chemicals, or chlorine can lead to this type of conjunctivitis. Improper use or contaminated contact lenses can also lead to the problem.
- Neonatal conjunctivitis: It affects newborn babies due to blocked tear ducts or exposure to maternal bacteria during childbirth.
