Shadows cast by retinal blood vessels mapped in primary visual cortex. If you are seeing the phenomenon, and you lightly press inward on the sides of your eyeballs at the lateral canthus, the movement stops being fluid and the dots move only when your heart beats.Adams, D.L., and J.C. The left and right eye see different, seemingly random, dot patterns a person viewing through both eyes sees a combination of both left and right visual field disturbances. The dots appear in the central field of view, within 15 degrees from the fixation point. The dots' rate of travel appears to vary in synchrony with the heartbeat: they briefly accelerate at each beat. The dots may appear elongated along the path, like tiny worms. Some of them seem to follow the same path as other dots before them. The dots are short-lived, visible for about one second or less, and traveling short distances along seemingly random, undulating paths. The blue field entoptic phenomenon is an entoptic phenomenon characterized by the appearance of tiny bright dots (nicknamed blue-sky sprites) moving quickly along undulating pathways in the visual field, especially when looking into bright blue light such as the sky.
