Mmm this might sound stupid, but...
I have a 'Lazy Eye' or in medical terms Amblyopy, which gives me a hard time looking through binoculars, not telescopes though because those work fine with 1 eye. My eye does not, which is a misconception by many, drift of to one side while I am looking at something, which only happens in select cases. It's just the connection to the brain which is very bad for 1 eye, which makes my vision shift more to my good eye. So for someone with healthy eyes it would look like your vision is centred wrong. Close your one eye and look through through it, I sort of have 1 eye open and a half eye open on the other side.
Now the question is, can I see 3D on my screen if it would work in CoD? I could just go out to town and find a pair of 3D glasses my own but I'm too lazy I guess
My own guess is that I can see 75 % 3D, but how that will look like I have no idea.
