What are floaters:- Eye floaters appear as small moving objects in the field of vision specially while looking at a plain or bright background (like the sky). These eye floaters appear as black dots or lines or thread like strands or ring shaped. Most of the times they do not interfere with the sight but occasionally if the floater is large it may cast subtle shadow over vision.
Eye floaters are caused by a protein called collagen. The eye is filled with a gel like substance called vitreous humor. Over the time this vitreous and collagen fibres shrink and shred and float around in the vitreous gel and are thus called as floaters.
