I’ve only heard of that particular test once. They shined a light on the wall and forced them to guess where. All I’ve heard is that they do “better than should be possible for someone who is truly blind”, so I’m assuming worse than average but definitely still processing the information to some degree.
Given that it’s a neurological condition, I’d expect it to be impossible to have it in just one eye/brain side, since the damage is occurring well after the signal from both eyes is put together.
What if you force them to verbally guess about what’s in front of them, can they do better than chance guessing colors, faces, etc.?
Can people get it in just one eye/brain side?

EDIT: http://en.wikipedia.org/wiki/Blindsight is a decent overview of the phenomena. Apparently it can indeed affect just part of your vision, so I was wrong on that!
