Moving the eyes up and down is an at-home remedy to remove eye floaters from the vision field. Most eye floaters do not require medical treatment. However, if numerous eye floaters begin to affect vision, they can be removed via a surgery known as a vitrectomy, notes WebMD.
Eye floaters are usually caused by age-related changes in the eye, often occurring after age 50. Eye disease, injury or tumors are other less common causes of eye floaters. Patients experiencing eye floaters accompanied by pain, vision loss or light flashes should visit an eye doctor for further evaluation, according to WebMD.
