thanks for the reply, but this link does not match my experience, I have had experience with floaters and know what they are.

Also " Scheerer's phenomenon is distinguished by the appearance of multiple, identical-looking bright dots that follow each other rapidly along the same path. Floaters are variable in appearance; although they sometimes are dots, they often have the appearance of threads or shreds of crumpled cellophane. "

As these dots appear always in the singular and are stationary when they appear, I doubt it could be Scheerers...
