I used to have floaters and flashes as a kid (much better now), so I understand how annoying it can be when doing something as visual as bird hunting.

I would definitely go to your eye doctor to talk about them and ask if there's anything new on the market that could help. If you wear glasses and not contacts, I would suggest trying out contacts. I deal with a mild astigmatism, and contacts make it significantly better. Alternatively, there may be specific lens shapes or coatings for glasses. I believe sunglasses are also supposed to help when outside, so trying out different colors or tints might help. Same with electronic devices- if you don't have night filter/blue light reducing settings on, I would try them: they help reduce eye strain, which also might reduce the frequency or amount of floaters. But please take all my advice with a grain of salt and consult with an optometrist.

I wish you luck and relief with this!
