What Is Pink Eye (or Conjunctivitis)?

Ever get a red irritated eye out of seemingly nowhere? There is a good chance that you have had pink eye or conjunctivitis.

Pink eye is actually a viral infection (or much less commonly a bacterial infection) of the white part of the eye causing inflammation and swelling and watering (bacteria causes a thick discharge instead). The white part of the eye is called the conjunctiva, thus the term conjunctivitis (note: the term conjunctivitis also is used with other causes of inflammation of the conjunctiva such as with allergies). Irritation of the conjunctiva causes the eye to feel irritated for a week or two but rarely causes any blurry vision. Because pink eye is typically caused by a virus, it is also common to have viral cold-like symptoms prior to the eyes becoming red and irritated.

Fortunately this viral infection runs its course without really causing any issues to the eyes. Despite this, however, it is still important to see your eye care provider in case the pink eye is caused by something like a bacteria that requires antibiotics. The main treatment with viral pink eye is to help make the eyes feel more comfortable. Artificial tears can help with the irritability. Also important is to prevent spreading it to others. Wash hands frequently and avoid sharing towels. And before you know it, your eyes will be feeling better!
