Eye Floaters Often From Age-Related Causes, Physician Says

For the most part, eye floaters — spots in the eye that can look like specks, strings or cobwebs — are annoying, but for the most part, the viewer doesn’t have to do anything about them.Most eye floaters are caused by age-related changes, according to the Mayo Clinic. Here’s how they can happen, according to Dr. David Gamm, who is the director of the McPherson Institute of Eye Research at the University of Wisconsin-Madison. As people age, the jelly substance in the middle of the eye, vitreous, loses its firmness and becomes more liquid. As that happens, the proteins and molecules that make up that substance band together and form strings or balls. They then float around in that core liquefied area in the center of the eye.
