The Force is Strong With This One
I too see phosphenes but couldn't for the life of me figure out what they were called.

Try looking into "phosphenes", "floaters" and "leukocytes" to compare descriptions... in fact, just now I saw a phosphene.
http://en.wikipedia.org/wiki/Phosphene#Phosphenes_in_daily_life said:The most common phosphenes are pressure phosphenes, caused by rubbing the closed eyes. The pressure mechanically stimulates the cells of the retina. Experiences include a darkening of the visual field that moves against the rubbing, a diffuse colored patch that also moves against the rubbing, a scintillating and ever-changing and deforming light grid with occasional dark spots (like a crumpling fly-spotted flyscreen), and a sparse field of intense blue points of light. Pressure phosphenes can persist briefly after the rubbing stops and the eyes are opened, allowing the phosphenes to be seen on the visual scene. Christopher Tyler (1978) has published drawings of pressure phosphenes. One example of a pressure phosphene is demonstrated by gently pressing the right side of your right eye or the left side of your left eye and observing a colored ring of light on the opposite side.
