I got my TBI 10 years ago (falling off a bike, *with* a helmet on - if I hadn't been wearing a helmet - !!!!). I know I'm lucky to be alive, and in as good a state as I am in, but...
I am 'blind' - that is the official term, but in fact I just have awful eyesight - when I look straight forward, everything to the left looks fine, but I see nothing to my right. If I *look* over to the right, I can see there, fine, but a huge part of my field-of-view is completely missing. There is *no*way* I can drive, anymore!
I also find that, if I look straight forwards, everything is fine, but if I swivel my eyes down, I see two images - one is the 'real' one, but the second is wonky, much lower, and off to the right. When I 'woke up' (or, as far back as I can remember, anyway), six months after my accident, I had to wear a patch over one eye all the time, because I saw double, everywhere. Thankfully, that problem has gone away, when I look straight forward, but it is still there, when I roll my eyes down.
These days, I am doing some 'exercises' for my eyes. Instead of rolling my head (so I look straight out of the front of my eye sockets), I roll my eyes, and look down. I do this while I am outside, walking - I spot something on the pavement, ahead, and I keep staring at it, as I walk towards it, so I have to roll my eyes down. I start off with just one image, but then it splits into two. I know which one is the right one (as it is stronger); the other one is weaker, and wonky, and they get further and further apart.
I have been doing that 'exercise' for a while, and I *think* I'm getting better (although I am not certain - How bad did it used to be? Was it worse? Hmmm...). The 'real' image seems stronger, and the 'silly' image seems less intense. Fairly recently, I've started doing it when I am reading, as well. The toe of the page is easy, as there is just one image, but as I get further down the page, there are two images, and they get further apart... It *is* hard work (and gets harder, the further down the page I go). Is it worth it? Will my vision always be as bad as it is, or will doing these exercises help? Is it worth me doing them?
