Vitreous floaters (eye floaters, vitreous opacities) are little “cobwebs” or specks that float about in your field of vision. They are tiny, cloudy clumps of cells that appear in the otherwise clear fluid (vitreous) that fills the back three-fourths of the eye. People see eye floaters as small specks, cobwebs, or clouds moving in their field of vision. They move as your eyes move and seem to dart away when you try to look at them directly. They do not follow your eye movements precisely, and usually drift when your eyes stop moving.
