Pink Eye and the Myths Surrounding It

Story at-a-glance

  • While this is a popular story told in schools, passing gas into a pillow does not actually cause pink eye, because the gas usually contains methane only
  • Viral conjunctivitis normally occurs when you have a cold, because virus-containing droplets from a sneeze may land on your eyes

Pink eye is one of the most common optical diseases, but there are myths on its causes and how it spreads that have gained considerable popularity through the years. Let’s take a look at a couple of the most common ones.1,2

When Is Pink Eye Contagious and When Is It Not?

As you’ve read in the myths listed above, some types of pink eye are not contagious. The first one is called “allergic conjunctivitis,” which occurs due to exposure to dust, spores and animal dander. These allergens cause swollen and itchy eyes, along with a burning sensation.3

The second noncontagious form is “irritant conjunctivitis.” This occurs when foreign objects enter your eye, such as shampoo, chemical fumes or a dislodged eyelash. Normally, the irritation goes away shortly after the exposure is gone and when you’ve washed your eyes with running water. But if pain continues to linger, it’s best to visit a doctor immediately.4

The remaining two types of pink eye are contagious, namely viral and bacterial conjunctivitis. Viral conjunctivitis normally occurs when you have a cold, because virus-containing droplets from a sneeze may land on your eyes. The same concept applies to bacterial conjunctivitis — contact with surfaces infected with bacteria, and then touching your eyes afterward may result in infection. If you don’t wash your hands frequently, you may pass on the bacteria to others as well.
