I can't stress this enough that anyone with a brain injury/concussion symptoms that linger needs to see a Neuro opthamoligist. there could be many eye issues with Brain injuries but the most common is convergence insufficiency which is where the eyes can't focus properly.

Tinted/prism glasses can help with this. I have been wearing them for 4 years. It can be hard to find someone and it may end up that you don't have this issue, but at least you can then rule it out. Feel free to Message me with any questions.
