I’ve heard 3D causes headaches. is that true?
Most people watching 3D suffer no ill effects after a brief orientation period lasting a few seconds as the image “snaps” into place, but in others, 3D can cause disorientation or headaches after extended periods. Viewer comfort is a major concern of 3D content producers; too much of a 3D effect can become tiresome after a while, abrupt camera movement can be disorienting, and certain onscreen objects can appear blurry, for example. Creators of 3D movies for children also have to account for the fact that a child’s eyes are closer together (about 2 inches) than an adult’s.
