I've had them for many years also. I noticed that some had either shrunk or were gone altogether. A few days ago I noticed a new one that came out of nowhere. I have regular yearly eye exams. I saw where there is a supplement you can take that claims to reduce their size and eliminate the smaller ones. It's advertised on Amazon and I was just curious if anyone had tried it and what the results were.
I have had cataract surgery on both eyes and have early signs of macular degeneration. I have never had a floater problem other than what might be considered normal. No more than what I saw 60 years ago. Everybody sees them every now and then.
