LG 3D Active Glasses AG-S250

• Use these genuine LG Active 3D Glasses to access 3-dimensional films, TV shows and games through your LG Plasma 3DTV. 
  
  Ideal for use with Blu-ray players and a home cinema system, this singular pair of glasses delivers high-quality visual performance. It features an adjustable nose pad and a rechargeable battery, for comfortable long-term usage.
  
  "Active" 3D glasses feature battery-powered crystal screens in each lens, which switch between opaque and transluscent too quickly to tell, to block the view from one eye at any one time, while retaining the illusion that both eyes can see correctly. The screens synchronise with your 3DTV which switches between showing images for your left and right eye when the corresponding lens lets the image through. 
  
  Happening at a speed too fast to notice, your TV shows each eye a different image, creating the illusion of depth. Because the image itself doesn't have to be altered as it is with "Passive" glasses, these glasses consider deliver what is considered to be higher performance than passive systems.
