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.
Not necessarily. If you are in very bright lighting, your pupils will constrict to limit the amount of light allowed to enter your eye. This protects the retina from damage. Likewise, in very low light levels, your pupils will dilate (enlarge) in order to allow more light into the eye and improve vision. This is a normal process.
