I also see this, I have been seeing these little prickles of light darting around for about 8 years. I that time not one doctor has been able to tell me what it is, ad I too have had people telling me my eyes are healthy. It is only recently that I found articles (such as your post) which sound like what I am seeing. I am sorry to hear that you have to suffer them also, but I am glad to hear that I am ot the only one. I was, and still am to a certain degree, worried about it.
