Afaik, unless you have eye surgery, floaters are stuck in your eye forever, it’s just that many eventually sink out of your field of vision. If you have large new floaters, especially if there are multiple new ones that appear suddenly, I’d recommend seeing an eye doctor - it’s how I found out I’d torn my retina, which was at risk of detaching and possibly making me partially blind.
You don’t have to do massive or big tournaments - go small instead! More fun and way less pressure. I’ve done a few ttrpg tournaments at GenCon and another few at my LFGS. My sister sometimes did small local puzzle tournaments like for KenKen and Sudoku.
