Well, it is very easy for people to get confused about pink eyes and sore eyes. So first you should know that Pink eye is a bacterial infection caused by Staphylococcus or Streptococcus bacteria. Also, it is very contagious, so it can be very dangerous if you are with someone who has this disease. And also you should wash your hands frequently if you have it. On the other hand, a sore eye can be caused by anything, such as a blow to the face, even something you do not care about. But you can not judge them by yourself. If you have some problems, I will suggest you go and see a doctor and he can give you some eye exam. So that you can know what kind of disease you have got.
