Gamemaker Nintendo is warning kids under six years old to stay away from its 3D games.
Nintendo issued new guidelines on its Japanese website saying 3D causes both kids and grownups more eye strain than 2D video games. All players are warned to take a break every half hour or so and to quit immediately if they feel queasy. The biggest worry is over the littlest players since their eye muscles haven’t finished developing. Parents can set controls on Nintendo devices so kids can only play in 2D. Tech-blog Engadget says there aren’t a whole lot of medical studies of 3D technology’s effects on vision yet, so it’s best to play it safe.
