2. Bacterial infections
When Pink Eye is caused by bacteria, the culprit may be staph, Haemophilus influenza type b, cat scratch disease, or Gonorrhea. Symptoms unique to this type include slightly more discharge and of grey or yellowish color, eyelashes sticking together, and swelling of the upper eyelid. Some mild pain may be present as well.
This is how you can figure out which type of Pink Eye you may have. This type is extremely contagious as well, and so isolation is the golden standard here. This type does have treatment with antibiotics, however. So, healing time can be cut in half with these.
