About floaters...: Floaters are due to imperfections in the clear gel inside the eyeball, and tend to become noticeable as a person ages. Floaters occur in many people, and sometimes are more noticeable if one is looking at a plain blank surface such as a blue sky. Large numbers of floaters, noticeably increasing floaters, flashes of light, changes in vision clarity, etc., can be evaluated by an MD eye doctor.
