Pink Eye

  When I got a cold a few weeks ago, I also got pink eye for the
  very first time. Although it had almost disappeared by the time
  I went to the doctor's, my doctor gave me eye drops anyway.
  Although the pink eye is gone, I seem to either have a
  "floater" or dark spot in that eye now. It's not always in the
  same place and changes shape somewhat (a dark spot with two
  streaks coming from it), so I'm assuming it's just a floater,
  but I was wondering if this was normal after pink eye? It
  doesn't seem to be going away, and is sometimes distracting as
  I often work in a computer with a white background.
  Also, it is possible that I have Lupus, and I understand
  that there can be eye problems related to this disease (I don't
  know if that helps you or not).
  I was hoping if you could tell me if I need to be concerned
  about this "floater". Thanks very much for your time--it is
  appreciated.

Dar,
Pink Eye is a form of conjunctivitis which is caused by a virus.  This can be very infectious and can spread from one eye to the next.  It usually gets better on its own.  Sometimes it is difficult to separate it from a bacterial infection so antibiotic drops may be given.
Pink Eye is an infection of the outside of the eye and should not cause "floaters".  Floaters are usually caused by something in the vitreous which is a jelly-like substance in the eye.  The vitreous itself can change with aging and cause floaters.  Floaters can also be caused by bleeding or inflammation in the vitreous.  Floaters and flashing lights can also be signs of a retinal tear / retinal detachment.
It would be reasonable to have an ophthalmologist examine your eyes determine the cause of your floater.
