The American Society of Retina Specialists says this detachment rarely occurs in people under 40, and eye floaters become more prevalent in people 60 and up. 2. Retinal tear
Floaters are, in fact, visible only because they do not remain perfectly 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 through neural adaptation.

The first two sort of floaters may collect over the fovea (the center of vision), and therefore be more visible, when a person is lying on his or her back looking upwards. Blue field entoptic phenomenon has the appearance of tiny bright dots moving rapidly along squiggly lines in the visual field.
Peripheral (posterior) vitreous detachment occurs when the gel around the eye separates from the retina. This can naturally occur with age. However, if it occurs too rapidly, it can cause photopsia which manifests in flashes and floaters in the vision. Typically, the flashes and floaters go away in a few months.

[13] Floaters: Tiny particles drifting across the eye. Although often brief and harmless, they may be a sign of retinal detachment.
In contrast, floaters are specks or threads of variable diameter and variable visual sharpness, some of complex shape, darker than the background. If the eye stops moving, the floaters settle down. If the eye moves, the floaters follow sluggishly, because they are contained in the vitreous humor , which, being gelatinous, is subject to inertia.
