You need a proper dilated retina evaluation by ophthalmologist to know the cause of so many floaters. If your retina is normal then taking Antioxidants might reduce your floaters to some extent and you will start to ignore them eventually.

Hi ..again not much can be done about this. But one check up should be done to see why there r so many floaters at this age.

Sir floaters issue is a very common one. These are more evident when you look against a clear background like a clear white wall or clear sky. Floaters can get reabsorbed but how much time it will take no one can predict . If the current floaters are reabsorbed a new one can form too. If there is a sudden increase in number of floaters or if there is sudden disturbances or decrease in vision or if you see some flashes of light like camera flashes then immediately meet any nearby Retina specialist.
