Thank you all for your time and kind answers.
I met with my doctor last week and we agreed to a referral for a vestibular assessment (physiotherapy) and I will also be seen by an optometrist who is supposed to be knowledgable of vision trouble following a concussion.
I had also found about computer glasses who are supposed to help with eye strain (blocking blue light) when doing computer work. I ordered a pair thinking I had nothing to lose, and all I gained was a headache
Hopefully, physio and optometrist will be helpful.
Thanks again!
