I never counted my floaters but I got 'cobwebs', 'spiders', grey 'clouds', dots and 'worms' all over the place in both eyes
@Mycatkaz. The majority of mine occurred after experiencing flashing lights in both eyes (due to gradual vitreous detachment) and some after what was probably an 'ocular migraine' (in combination with vitreous detachment) in my right eye.
It took many months for me to not notice my floaters and that was partly because I was at first worried about them (and got things checked out, just as you have done) and then upset and really angry about them. I gradually stopped feeling like that though and I also stopped 'assessing' them and then eventually I stopped noticing them. I can't tell you exactly how long that took, but I estimate that it was probably over a period of about a year to 18 months; the brain needs some time to adjust and tune them out.
With regard to the brain adjusting and tuning floaters out, an example of the brain being able to do such things is with strabismus. People with strabismus see double images, but the brain usually adapts by shutting down or ignoring the information from one eye. I have experience of this as I have 'monocular' double vision in my right eye due to a cataract but, although my left eye also has a cataract, it isn't as bad as the one in my right eye, and I don't see double when I use both eyes together. This is because my brain ignores the double vision in my right eye. Cataracts 'grow'/form gradually and so I didn't realise this adaption was happening until I had an eye test during which my left eye was covered and I was asked to read a back lit eye chart with my right eye -- and everything was doubled/blurred. (I also have fluctuating 'binocular' double vision but that's another story and quite a different kettle of fish.)
Anyway, back to floaters...Now, if I intentionally look for them, I can still see some of my floaters, e.g. one particularly dark one top right in my right eye and another grey cloud-like one that comes across the pupil of my left eye, but I don't generally notice any of my floaters to include those ones as I go about my daily business.
Floaters can also slowly sink within the vitreous and eventually settle at the bottom of the eye. When this happens, you don't see them anymore and you are likely to think they have gone away. I believe that some of my floaters have almost certainly sunk.
