Eye Floaters are little worm like specks drifting aimlessly in your field of vision. Medically speaking, they are simply shadows cast by objects suspended in the vitreous humor, the clear, gel-like substance that makes up eighty percent of the interior of your eye. While seven in ten people claim to experience them, in ninety-nine percent of cases they are completely harmless.
They occur naturally in your eyes due to simple proteins of vitreous gel clumping together, vitreous gel naturally shrinking as we age, (allowing for bits of debris to enter the gel), and red blood vessels being pulled into the vitreous gel causing minor hemorrhages. (These are not harmful and disappear as the blood is absorbed.)
Only on very rare occasions, (less than one percent of the time), do they have the potential to develop into something harmful. Where this is the case, nearsighted people, diabetics and people who have had cataract surgery, are most at risk. They occur most often in people between the ages of fifty and seventy-five.
