What is Floater mean?
Floaters or eye floaters are sometimes visible deposits within the eye's vitreous humour ("the vitreous"), which is normally transparent, or between the vitreous and retina. Each floater can be measured by its size, shape, consistency, refractive index, and motility. They are also called muscae volitantes (Latin for 'flying flies'), or mouches volantes (from the same phrase in French). The vitreous usually starts out transparent, but imperfections may gradually develop as one ages. The common type of floater, present in most people's eyes, is due to these degenerative changes of the vitreous. The perception of floaters, which may be annoying or problematic to some people, is known as myodesopsia, or, less commonly, as myodaeopsia, myiodeopsia, or myiodesopsia. It is not often treated, except in severe cases, where vitrectomy (surgery), laser vitreolysis, and medication may be effective.
Floaters are visible either because of the shadows imperfections cast on the retina, or because of the refraction of light that passes through them, and can appear alone or together with several others as a clump in one's visual field. They may appear as spots, threads, or fragments of "cobwebs", which float slowly before the observer's eyes, and move especially in the direction the eyes move. As these objects exist within the eye itself, they are not optical illusions but are entoptic phenomena (caused by the eye itself). They are not to be confused with visual snow, which is similar to the static on a television screen, although these two conditions may co-exist as part of a number of visual disturbances which include starbursts, trails, and afterimages.
