Can you tell me the difference between pink eye and a regular eye infection?

Conjunctivitis: Pink eye is the colloquial term implying a viral conjunctivitis. Thus this type of eye infection is more contagious, but regular eye infection can include all conjunctivitis types such as viral, bacterial, allergic, etc.

Pink eye: Classic adult pink eye is generally caused by a cold virus....This is quite common and varies in severity...Not sure what you are referring to with a regular eye infection...
