Floaters are deposits of various size, shape, consistency,
refractive index, and motility within the eye’s vitreous humour,
which is normally transparent. At a young age the vitreous is
perfectly transparent but, during life, imperfections gradually
develop. The common type of floater, which is present in most
people’s eyes, is due to degenerative changes of the vitreous
humour. The perception of floaters is known as myodesopsia.
Floaters are visible because of the shadows they cast on the
retina or their refraction of the light that passes through
them, and can appear alone or together with several others in
one’s field of vision. They may appear as spots, threads, or
fragments of cobwebs, which float slowly before the observer’s
eyes. Since these objects exist within the eye itself, they are
not optical illusions but are entoptic phenomena. I HAVE BEEN
