I have a problem with 3d in that my eyes never converge, period. I have keratoconus and have had surgery in my left eye, the end result of which is that my eyes have different vision levels, the left being much better than the right. My right eye drifts off a bit (lazy eye) and I focus with my left (better) eye. The entire premise of 3d basically excludes me.
