If your original avatar (the one you chose when you joined Second Life) was a vampire, it might have prim eyes attached to your avatar. I know mine did. When you open your "Appearance" tab inworld (it might be called something different depending on your viewer), try and look for objects called "Eye left," "Eye right," or something like that. Detach those objects and give your avatar a second to load.
Hope this helped :robothappy:
