Howcome the Virtual Boy causes light headaches with some people after playing it for awhile?
A. Some people are more sensitive for this than other, but the cause is that the Virtual Boy’s two screens get bombarded with a great number of images (called frames) per second, the two screens don’t display the exact same image, one of the two is shifted a bit more than the other, thus creating the 3D display when you look at both at the same time, but for some people this causes an awkward feeling resulting in a most often light headache.
