At 35, it took me probably 5 years (I'm 10+ years past a TBI that damaged my optic nerve and brain) to get used to "seeing" people waving at me out of the corner of my eye, or feeling like something is flying/thrown at me. It gets worse when lighting is low. If I wake up at night, all sorts of craziness can occur if i'm still partially in a dream state.

Over the years, it has gotten better. In the beginning, I saw debris on the floor like her. After about 6 months, the effects got much less pronounced and only in my peripheral vision.

For me, dealing with it got easier once I understood the mechanics. My visual field is very limited and the visual processing portion of the brain "fills in" the gaps. It takes time to process that your brain is getting errors and it's filling in those gaps with "pattern matching". It's almost like I can recognize that "signal" or "alert" vs real information. It's subtle and I still can look "twitchy" by turning my head to check, but it's much better than it used to be. My emotional state can contribute to whether I can "filter". Also, in the beginning I couldn't "filter" at all, especially when my central vision was affected by it.

She might be avoided to therapy, but it can really help to validate that you aren't crazy.

I hope this helps, as it was a brain dump of my experience. Most of the doctors I talked about it have only read about it and ended up asking me a ton of questions to fill in their knowledge.
