Pink Eye or Conjunctivitis | Symptom, Causes And Treatment


pink eye


Pink Eye is an infection that affects the membrane that covers the white of our eyes and inside of your eyelid  (Conjunctiva). Hence it also called as Conjunctivitis. It can happen to one or both eyes.

The membrane gets inflammation. The blood vessels in white eyes dilate (enlarge), hence it becomes red. That’s why conjunctivitis is sometimes called as Red eye or pink eye.

Anyone can get pink eyes, but office workers, factory workers, school teachers & children or any other person who works in a group are at high risk because of contagious disease.
