Sorry OP I got floaters when I was 39. I had a small accident with my eyes (getting something in them) which I think caused it but the optician said no.
Anyway I was literally fine and then the next day at work i started seeing 'flies' flying about in front of me and kept trying to swipe them away. Then I realised there was nothing there and it was black dots with tails in my eyes.
I worked on spreadsheets alot (white background) and so it was incredibly distracting and the floaters would dance over the numbers and make my job very difficult. In fact i would go so far as to say it had a huge detrimental effect on my career as I could no longer concentrate on huge complicated spreadsheets with lots of numbers. It did cause me alot of problems and anxiety for a few years till I 'adjusted'.
I eventually had to change jobs to a much easier one where spreadsheets were a small part of it and so yes you could say it impacted my earnings.
I also developed really dry eyes and now have to put in eye drops day and night (well the night stuff is ointment). 15 years later the dry eyes still bother me and I am pretty sure my huge eye bags are due to the constant fiddling with my eyes getting the drops in.
However the floaters stopped bothering me after a couple of years. I did change jobs as I said but they used to bother me in bright sunshine when driving (in fact I nearly had an accident when I first got them in bright sunshine when driving). Now I literally NEVER see them. I do look at spreadsheet occassionally now (more home use) and I don't see them doing this either.
I am a terrible worrier with high anxiety and poor MH and honestly for me when it happened it was like a 'crisis'. Now I literally don't even remember i have them. If I try to see them then I can make myself see them (so they are still there) but if I don't then I honestly don't see them.
The dry eyes have given me much more bother as the years went on.
So I am not minimising your experience at all. For me it was a 'devastating' event which really had quite a big impact on my life and career. I was angry at the opticians for not being able to fix them.
I promise you if I have forgotten all about mine you will get over yours too. I promise you in a few years you will have adjusted and your brain will compensate for them. Don't ask me how it works, it just does. The optician told me this would happen and I thought what a load of 'bollocks' but it was actually true.
I hope that helps you and I completely understand your panic/distress just now.
