Samsungs rechardgeable 3D Active Glasses are the gateway to Samsung 3D entertainment. Impressive both in how they function and in what they allow you to experience, the technology works as follows: When you put them on and look at the screen, the technology first blocks the left and then the right lens. It happens faster than the blink of an eye – so your eye won′t notice it. But when images are shown to each eye separately this "staggered" effect achieves far more lifelike 3D images.
