Eye floaters are vitreous opacity suspended in the vitreous space, where the gel-like fuild fills in. a incident light flash into the retina, vitreous opacity will be projected onto the retina. Our neurosensory mechanism will transmit a message of various shadow corresponding to the pattern, shape, movement of the vitreous opacity. if the VO is dense and close to the retina, the shadow projecting on the retina will be significant . so, they generally follow the rapid motions of the eye, while drifting slowly within the fluid. When they are first noticed, the first reaction of most people is to attempt to look directly at them then they usually try to ignore . However, attempting to shift one's gaze toward them can be difficult since floaters follow the motion of the eye, remaining to the side of the direction of gaze. Floaters are, in fact, visible only because they do not remain perfectly fixed within the eye.
