A Guide to pink Eye (Conjunctivitis)

Untitled 4 01
Conjunctivitis commonly known as pink eye is the inflammation of the conjunctiva, a thin clear tissue in the eye. It can be extremely contagious and spread quickly, with rarely serious.

This article gives a clear idea about what is pink eye, it’s symptoms, treatment and complications.

What is conjunctivitis?

Conjunctivitis or pink eye is the inflammation of the conjunctiva, the transparent membrane that lines the eyelid and the eyeball. The swelling and inflammation make the small blood vessels in the conjunctiva more visible, giving it a pink colour.

Conjunctivitis may be caused mainly by viruses, bacteria, or by allergies.
  • Viral conjunctivitis
  • Bacterial conjunctivitis
  • Allergic conjunctivitis

Others include:

  • Non-specific conjunctivitis
    Develops in people who have dry eyes may occasionally or continuously.
    When comes into contact with chemicals, dust, eyelash, smoke, and fumes
    It may also occur if contact lenses are not properly cleaned
  • Toxic Conjunctivitis
    It is an ongoing inflammation of the eye’s surface brought on by an irritant, typically a preservative or medication

How does conjunctivitis spread?

Both bacterial and viral conjunctivitis can spread easily. The most typical routes for transmission are:
  • Direct hand-to-eye contact
  • Direct body fluid contact with an infected person
  • Use of improperly cleaned contact lenses

When should I seek medical attention?

  • Eye pain
  • When discharge from the eyes is wiped away, the pain in the eyes, sensitivity to light, or blurred vision do not go away
  • Intense redness in the eye

How can conjunctivitis be avoided?

One of the best strategies to prevent and stop the spread of conjunctivitis is to maintain proper hygiene:
  • Do not touch your eyes, especially with unwashed hands
  • Wash your hands thoroughly and frequently with soap.
  • To wipe your face and eyes, only use fresh tissues and towels
  • Avoid sharing cosmetics, especially eyeliner and mascara
  • Regularly wash your pillowcases

What is the ‘life span’ of pink eye pathogens on surfaces?

  • Certain bacteria can live for up to two days, but most of them are unable to survive after two to eight hours
  • In general, viruses are more resilient; the majority of them survive for 24 to 48 hours. Certain viruses can persist for up to 8 weeks
  • When surfaces are cleaned thoroughly, the majority of bacteria and viruses are instantly destroyed by bleach or another antimicrobial cleanser

Your conjunctivitis should typically resolve on its own within 1-2 weeks. If your symptoms persist beyond that point, you must consult an eye specialist (ophthalmologist). They can check whether you have a more serious eye condition.

  • Discard your old contact lenses and use new ones
  • Do not use any eye makeup while you have conjunctivitis
  • If you have bacterial conjunctivitis, cover your eyes for a few minutes with a warm, damp washcloth 4 to 5 times a day
  • In case you have viral conjunctivitis, place a cool, damp washcloth over your eyes for a few minutes. You may repeat this 4 to 5 times a day
