What gives me a headache is not being able to control the focus. Normally you can choose to focus on something close or far away. With a 3D screen, the focal point is always the same. Something that's not in focus on the screen can't be brought into focus. The problem is the same for non-3D screens, but they don't bother me(probably because I've been looking at 2D screens my entire life). The added 3D effect is what seems to trigger it for me.
