Eye floaters are deposits or condensation in the vitreous (often referred to as vitreous humor, vitreous fluid, or vitreous gel), the material that fills the posterior part of the eye. People use the term eye floaters to describe seeing floating spots within their vision when they look around. Eye floaters may be present in only one eye or both eyes.
Most eye floaters are caused by age-related changes that occur as the jelly-like substance (vitreous) inside the eyes becomes more liquid. Microscopic fibers within the vitreous tend to clump and can cast tiny shadows on retina, which appears as floaters.
Your doctor will conduct a complete eye exam including eye dilation to better see the back of your eyes.
In a survey of 603 individuals, 76% reported that they see floaters, and 33% reported that floaters caused noticeable impairment in vision. Vitreous floaters were found to be a very common phenomenon in this non-clinical general population sample, and more likely to be impairing in myopes and hyperopes.
