BB747, there are two things it's worth knowing about floaters:
First they are like tinnitus, if you think about them they are a pain, you notice them all the time. If you don't think about them you don't notice them. the brain is amazing at "filtering" stuff like that out so that you can function.
The more important thing is that they _may_ be a sign of something serious. This is not so much for you as you have had them for a while, but for others. If you suddenly develop floaters you should hot foot it to an eye surgeon for a check up. Some diseases of the eye, such as infections in the retina, create lots of floaters suddenly. So get them checked out.
