No one ever seemed concerned with mine. That is, until I ended up with a retina pucker when one stuck on my eye's retina and distorted it. Took almost two years for it to come loose, new prescription every couple of months as it distorted the focus. Better than then surgery.
Check with an ophthalmologist.
I have floaters. I have also had two retinal tears. My ophthalmologist advised me to get a thorough eye exam whenever new floaters show up.
