Your workers might complain about seeing “floaters” in their field of vision. What can you tell them? Eye floaters may look like black or gray specks, strings or cobwebs that drift about when you move your eyes, according to the Mayo Clinic.
Says the Mayo Clinic: Most eye floaters are caused by age-related changes that occur as the jelly-like substance (vitreous) inside your eyes becomes more liquid. When this happens, microscopic fibers within the vitreous tend to clump together and can cast tiny shadows on your retina, which you may see as eye floaters.
