I think I have this issue too. I’ve had floaters since I was a kid but always ignored them (or looked up at the sky so I could see them for fun). I’m 27 now and feel like I’ve got so many that I don’t know what i will do once they increase with age. I need to train my brain to ignore them again.

It makes a lot of sense that the brain will become more sensitive after a mild injury. I feel like I focus so much on how I can see that I end up not really seeing anything and straining my eyes!

I’m sorry you had a hard time with echoes, it must get exhausting. Anxiety makes everything so much worse.

I wish you all the best!
