Welcome to HCM.
I do understand how annoying is to have floaters
in your eye for a long time. Since you haven't mentioned your age, in general terms, floaters are deposits in the vitreous ( jelly of the eye), due to degenerative changes in vitreous . They are visible because they are mobile within the vitreous each time the eye moves and causes retinal shadows. They are harmless until they grossly increase in number and size within a short period.
If it is causing unbearable discomfort it can be removed through Vitrectomy
So get a Retina specialist opinion to see the extent of it and proceed accordingly. Take care.
