Active 3D TV uses alternating fields to generate two images for the 3D effect. It requires glasses that switch the image from one eye to the other. The glasses are battery powered but are now very lightweight. The resolution is at 1080 lines as normal HD Passive 3D or Cinema 3D as LG like to call their televisions split the image using alternate lines. The glasses don't need batteries but the resolution is cut down to 540 lines. That is even worse than standard definition of 576 lines.
It is called a glasses lanyard or a glasses strap.
Passive glasses are lighter, and a little cheaper than active glasses. Passive glasses are under £10 whereas active glasses start at a little over $10. Passive glasses need no batteries but the resolution of passive 3D such as LG is half that of other 3D systems at just 540 lines, lower than the standard definition of 576 lines that was introduced almost 50 years ago.
