  I’ve just looked this up for a good explanation, and found a NHS page explaining them! http://www.nhs.uk/conditions/floaters/Pages/Introduction.aspx
  
  They explain floaters as “small pieces of debris that float in the eye’s vitreous humour. Vitreous humour is a clear, jelly-like substance that fills the space in the middle of the eyeball.”
  
  They’re not normally something to worry about. I see them all the time.
