This depends on the underlying cause of the floaters.
People with a posterior vitreous detachment often find that their floater symptoms either reduce in severity or become more tolerable over a period of 2 to 3 months. This may in part be because the vitreous continues to change with the consequence that the opacity causing the symptoms of floaters moves further forward within the eye and casts a less formed shadow on the retina. Alternatively it may be that people become used to the symptom and learn to ignore it. The causative opacity within the vitreous does not go away but its visual effect becomes less. Inflammatory floaters may go away but this is often dependent on successful treatment being applied to the causative eye condition. The same can be said for syneretic floaters which can either become less symptomatic with time or remain troublesome.

Floaters resulting from a bleed or haemorrhage within the eye may clear on their own. It is, however, vital that the underlying cause of the haemorrhage within the eye is identified and treated in order to prevent serious complications arising in the future.
