When the spots appear rather fuzzy and seem to be strung together with a web-like thread, they are called floaters. Flashes are bright points of light that literally flash into the field of vision when the eyelids are open or closed. They usually appear as tiny dashes forming either an oval or a circle.
The aqua circle is a source as it would be seen if there was no lens; white spots are the multiple images of the source. A gravitational lens is a distribution of matter (such as a cluster of galaxies) between a distant light source and an observer, that is capable of bending the light from the source as the light travels towards the observer.
