If you've had a stroke or some other brain injury, you may have noticed changes in your vision - particularly on one side or the other. Although there are multiple possibilities, we just learned about this one - homonymous hemianopsia, which is the loss of half of the field of view on the same side in both eyes. It generally happens when the optic nerve communication to the brain is interrupted. You can read more about this and watch a video that explains it all here.
