Samsung has team up with Silhouette to deliver the lightest 3D glasses (at this moment). Together with this design, it also has a few features worth mentioning.
Apart from being the lightest 3D glasses, it has also wireless charging feature. And it is clever enough to identify 3D content to turn the shutter glass on or off.
BTW, the electronics are stored at the rear of the spec frame. And it makes the frame more balance and therefore, more comfortable to wear.
