Floaters and Flashes

Ask an Eye M.D. Answer Archive

Question:
How do I know if a floater is a sign of a serious problem? Also, are there general timelines for how long floaters last?

Answer:
Floaters may be normal. However, the sudden development of many new floaters or a significant change in your floaters can be a sign of another problem. Flashes of light may also accompany new floaters. Sudden and new symptoms should be evaluated by your Eye M.D. to determine if you have a retinal tear or detachment that might require immediate treatment to prevent vision loss. Some floaters come and go, others are visible for months or years. Most floaters will become less noticeable with time.
