Today we’re seeing stars!  Not the Hollywood type and not the ones in the night sky.  The stars I’m talking about are the ones you see after a bump on the head.  You know, like the ones swirling around cartoon characters.  Technically known as a phosphene, or seeing light when there is none.  In your eye you have a thin, light sensitive layer, the retina and a gel, or vitreous, that helps your eye keep it’s shape.  The “stars” are caused when thin fibers in the vitreous are pulled or the vitreous makes contact with the retina.  Common causes are a bump on the head, sneezing, coughing, blowing your nose or even getting up too quickly which causes a sudden drop in blood pressure.
