How long does it take for floaters in a person's eye to go away?

: It largely depends on the cause of the floaters. Gradual changes in a healthy aging eye may have the floaters persisting for years. Floaters due to blood in diabetes or a retinal tear can resolve in months with proper treatment. After vitreous separation they can resolve in months. Myopic eyes often develop floaters early in life which persist for years.

Floaters: It depends. It may take weeks, months, or years depending on the cause and how old you are. There are no eyedrops or medicines to get rid of the floaters faster. And surgery is not indicated.
