About Conjunctivitis:

 

  • Conjunctivitis, commonly known as Pink Eye, is an infection or inflammation of the transparent membrane that covers the eyelid and eyeball. This membrane is called the conjunctiva. 
  • Why do eyes appear Pink?
  • When small blood vessels in the conjunctiva become swollen and irritated, they’re more visible
  • This is what causes the whites of the eyes to appear reddish or pink.
  • Causative Agent:
  • It can be caused by viruses, bacteria or by allergies. 
  • Both bacterial and viral conjunctivitis are highly contagious, while allergic conjunctivitis is not. 
  • Transmission:  
  • It usually occurs through direct or indirect contact.
  • Direct transmission happens through droplets from the cough or sneeze of an infected person or through hand-to-eye contact..
  • Indirectly, it can spread via shared personal items like towels, makeup, pillows or contact lenses. 
  • Signs and symptoms:
  • Most common signs are redness, swelling and itching in the eyes.
  • The eyes can also feel watery during the start of the flu.
  • Treatment:
  • For the treatment of conjunctivitis, one needs to use a combination of medicines.
  • One of the most useful treatments is using artificial tears or even any lubricating eye drops; these can help the infected person to maintain moisture.
  • A warm or cold compress will also help in giving relief from inflammation and swelling.

 


Q) What is the eyeball?

The eyeball is a vital organ in the visual system of most vertebrates, including humans. It is a complex structure responsible for receiving and processing visual information from the surrounding environment. The primary function of the eyeball is to detect light and convert it into electrical signals that the brain can interpret as visual images.
