I have floaters, I was sitting down and noticed lots of insects crawling along the wall, then realisation hit. They are permanent but honestly the brain does adapt, however it is the end of clear vision
My floaters came like a shower after just a couple all my life. Optician told me to go in if it happens again. I let my specs get dirty on purpose, it disguised the floaters and I think enabled me to adapt. I have had no more big episodes
There is no treatment apart from replacing the vitreous jelly and that has risks. People who have had cosmetic eye laser treatment are more likely to get floaters as are the short sighted and lifting heavy weights can cause them too and age of course
I take very good care of my eyes, never go out without my wrap-over rnib sunglasses to block UVa and b
The best people to deal with questions are the well-trained opticians
