I just had an episode a few minutes ago. It was like sparkers (little silver dots) floating in both eyes all zigzaggy. Not stringy, just like watching little dots float down and away....several in each eye. I have never had that happen before. They went away within a minute. I do once in a while get spots in my eye like someone has put vaseline in it and I blink and blink thinking it will make the "debris" if it is debris go away. It usually does within a few minutes. But this episode today was differnt. It really was like "seeing stars." Should I be concerned?
