What Causes Conjunctivitis

Conjunctivitis occurs when the conjunctiva, the thin layer covering the white part of the eye and inside of the eyelids, becomes inflamed. The main causes include:

• Viral infections: These are the most common cause and often accompany cold or respiratory infections. Viral conjunctivitis spreads easily through contact with infected secretions.

• Bacterial infections: Bacteria like Staphylococcus or Streptococcus can cause conjunctivitis, often producing a thick, yellow-green discharge.

• Allergies: Allergic conjunctivitis results from exposure to allergens such as pollen, dust, or pet dander. It usually affects both eyes and is accompanied by itching.

• Irritants: Smoke, chlorine in swimming pools, or exposure to chemicals can also trigger conjunctivitis.

  
  

Knowing the cause is important because it influences the treatment approach.

Recognizing the Symptoms

Symptoms of conjunctivitis vary depending on the cause but often include:

• Redness in one or both eyes

• Itching or burning sensation

• Excessive tearing or watery eyes

• Discharge that may be clear, yellow, or green

• Crusting of eyelids or lashes, especially after sleep

• Sensitivity to light or a gritty feeling in the eye

  
  

For example, viral conjunctivitis usually starts in one eye and spreads to the other, with watery discharge and mild discomfort. Bacterial conjunctivitis often produces thicker discharge and may cause the eyelids to stick together. Allergic conjunctivitis is marked by intense itching and swelling.

Treatment Options and Care

Treatment depends on the cause of conjunctivitis:

• Viral conjunctivitis: This type usually clears up on its own within one to two weeks. Applying a cold compress and using artificial tears can relieve symptoms. Avoid touching or rubbing the eyes to prevent spreading the infection.

• Bacterial conjunctivitis: Doctors often prescribe antibiotic eye drops or ointments. It is important to complete the full course even if symptoms improve quickly.

• Allergic conjunctivitis: Avoiding allergens is key. Over-the-counter antihistamine or anti-inflammatory eye drops can reduce itching and swelling.

• Irritant conjunctivitis: Rinse the eyes with clean water and avoid further exposure to the irritant.

  
  

Good hygiene helps prevent spreading conjunctivitis. Wash hands frequently, avoid sharing towels or pillows, and replace eye makeup regularly.

When to See a Doctor

Seek medical advice if you experience:

• Severe pain or vision changes

• Symptoms lasting longer than two weeks

• Intense redness or swelling

• Sensitivity to light or intense discharge

  
  

These signs may indicate a more serious eye condition requiring prompt treatment.

Understanding conjunctivitis helps you respond quickly and reduce discomfort. If you notice symptoms, take steps to care for your eyes and protect others. When in doubt, consult a healthcare professional for proper diagnosis and treatment.
