Oh yes, I almost forgot to mention... light doesn't seem to help my vision problem. Computers, television, video games, fluorescent, candescent, etc. Even sunlight bothers me.
that's such a sad story, I wish i could help you.
how bad was your head injury?
if you don't mind me asking?
The most common cause would be a astigmatic refractive error, second would be corneal disease, third would be macular disease.
See an eye MD for an exam, have a Amsler grid test, corneal topography and a good refraction.
I don't mind you asking at all but I never got an actual head injury, just the lack air caused me to get dizzy and the dizziness faded but left me with this seemingly permanent slanting vision. I hope to God that it is not permanent.
