Floaters come and go with eye movements, such as blinking. They follow eye movements, but lag behind and float to a halt a few seconds after the eyes stop moving. These images are most obviously appear when looking at a bright, uniform field of vision, such as a white wall or a clear sky. People may experience one or several floaters in one eye or both. Floaters are not the same as the spots you see after looking at intense light such as from a flashbulb.
Most people see floaters some time during their lives.
Many individuals in their teens and 20s notice some floaters, and people who are nearsighted may have floaters at a younger age. Floaters become more frequent as a person ages. The type of floaters depends on what causes them. The majority of floaters are due to normal degenerative changes in the vitreous , the jelly-like floaters because of a retinal tear without a detachment, the tear usually can be treated with minor surgical procedures that can effectively prevent a retinal detachment. Patients whose floaters are due to bleeding from the abnormal growth of blood vessels can suffer one or more hemorrhages inside the eye that may severely affect vision.
