Well i have not got the 3ds But now im going to save up i almost got enough but if they hurt my eyes or give me headeches i dont want to buy it. i look into it.
your answer is yes and no.. the 3ds at first might hurt your eyes or make you dizzy but this only lasts about an hour or so. the human eye isnt use to seeing things like this and it just need to adjust. after a while it will be just like looking out a window when you play
