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.

A small percentage of people who develop the abrupt onset of prominent floaters or light flashes in an eye will be found to have a retinal tear on careful ophthalmoscopic examination.
