“How long do eye floaters usually last?”

Eye floaters are typically caused by changes in the vitreous humor of the eye. While they can be bothersome, they often do not require treatment and may become less noticeable over time. The duration of floaters can vary from person to person, lasting from weeks to months to even years. If you experience a sudden onset of new floaters, flashes of light, or visual disturbance in your vision, it is essential to have a visit with your eye doctor.

A lifetime- if they're the benign floaters which are strands of collagen in the vitreous which have clumped together. You need a dilated eye exam to determine the type of floaters and if treatment is needed.

Short answer is for life, although they can migrate out of line of sight, so they can't be seen. As long the floaters are small, they are probably harmless. If large, cobweb shaped, they should looked at by your eye doctor.

It depends on the severity, some may disappear and some new ones can appear due to aging of the eyes. Large ones may never disappear,

Floaters are found in the vitreous part of your eye. If these are floaters that have been noticed by you for some time, they are probably some of the "floating debris" that is within the vitreous. If these are new, dark particles that were not there before, I would definitely have your eyes checked and dilated by an eye doctor. There are warning signs of vitreous detachments or retinal tears or detachments that can include new floaters, flashes of light, "clouds or curtains" coming over your vision, loss of vision, visual field changes, or anything unusual that has not been noticed or "seen" before these things happened. Floaters will never go away; they are self-contained within the vitreous. Some, depending upon their weight and density may "settle down" where you may not see or notice them within your line of sight. Again, please see an eye doctor so that you have the information that you need and so that your eye doctor can best inform you as to why these floaters are actually there at the present time. Good luck and best wishes.

Floaters are not pathologic findings. They are normal changes in the eyes. They will come and go. No treatment is needed.

Depends. They can dissolve on their own or you live with them or you get them lasered out.
