More about Flashes and Floaters
Flashes and floaters can be more often a nuisance than an actual cause for alarm. However, as mentioned, the sudden onset of new, many, and larger-size floaters may indicate a serious condition and you should see your ophthalmologist immediately. Should a serious condition be developing, such as a tearing or detaching retina, a timely surgical repair can take care of the problem.
Treatment
In general, floaters do not require treatment and usually diminish over time. Any treatment that is warranted is directed to the underling cause of the flashes or floaters.
