For those who like technical terminology and Greek, the medical term for when you lose the one side your left and right eyes' vision—is hemianopsia (hemi- "half" + an- "not" + opsia "seeing").

There are several types of hemianopsia depending on how far upstream or downstream the nerve damage occurred between your eyes and your cerebrum. When it happens because one of your cerebral hemispheres got damaged, then you get homonymous hemianopsia (same-sided hemianopsia):
