Is there a natural way to get rid of floaters?

No. Sunglasses can help to relieve their presence on sunny days or at the beach.
No. Floaters are caused by shadows of inconsistencies in the vitreous gel. They may appear early in eyes which are nearsighted but should be evaluated if they are of new onset. They may represent blood in cases of diabetes or following trauma or after the vitreous separates. Adjusting lighting using directional lamps as opposed to fluorescent lamps may help reduce their annoyance.
