Simply stated, any damage to the eye that causes material to enter the vitreous humour can result in floaters. Citation needed Floaters can occur when eyes age and in rare cases, floaters may be a sign of retinal detachment or a retinal tear. 9 Vitreous syneresis edit The most common cause of floaters is shrinkage of the vitreous humour. This gel-like substance consists of 99 water and 1 solid elements. The solid portion consists of a network of collagen and hyaluronic acid, with the latter retaining water molecules. Depolymerization of this network makes the hyaluronic acid release its trapped water, thereby liquefying the gel. The collagen breaks down into fibrils, which ultimately are the floaters that plague the patient. Floaters caused in this way tend to be few in number and of a linear form.

Most persons come to terms with the problem, after a time, and learn to ignore their floaters. For persons with severe floaters it is nearly impossible to completely ignore the large masses that constantly stay within almost direct view. Floaters have been reported in patients as young. Citation needed Floaters in teenage patients and young adults are usually harder to treat. For persons in this age group, the floater that is seen usually looks like a kind of translucent worm/web/cell. Very little is known about this region, and it only becomes distinct after the vitreous humour detaches from the retina at later stages of life. Due to their microscopic size they cannot be seen by doctors. They only appear as big as they do because of their proximity to the retina. This type of floater is still described occasionally in people in their 30s betekenis and very rarely occurs in people in their 40s.

8 However, floaters are more than a nuisance and a distraction to those with severe cases, especially if the spots seem to constantly drift through the field of vision. The shapes are shadows projected onto the retina by tiny structures of protein or other cell debris discarded over the years and trapped in the vitreous humour. Floaters can even be seen when the eyes are closed on especially bright days, when sufficient light penetrates the eyelids to cast the shadows. It is not, however, only elderly persons who are troubled by floaters; they can also van become a problem to younger people, especially if they are myopic. They are also common after cataract operations or after trauma. Floaters are able to catch and refract light in ways that somewhat blur vision temporarily until the floater moves to a different area.

fixed within the eye. Although the blood vessels of the eye also obstruct light, they are invisible under normal circumstances because they are fixed in location relative to the retina, and the brain "tunes out" stabilized images due to neural adaptation. This stabilization is often interrupted by floaters, especially when they tend to remain visible. 2 Floaters are particularly noticeable when looking at a blank surface or an open monochromatic space, such as blue sky. Despite the name "floaters many of these specks have a tendency to sink toward the bottom of the eyeball, in whichever way the eyeball is oriented; the supine position (looking up or lying back) tends to concentrate them near the fovea, which is the center. 5 The brightness of the daytime sky also causes the eyes' pupils to contract, reducing the aperture, which makes floaters less blurry and easier to see.
