Understand 3D glasses
There are various kinds of 3D glasses. The ones you should use for your TV depends on what type of 3D your TV displays. Take a look at your choices:

3D DUAL PLAY
3D Dual Play glasses are made for two-player split-screen gaming. While wearing the lightweight battery-free glasses, each player can see only their character's point of view (in 2D) across the entire screen. Which means no more squinting at a smaller split-screen view and no more cheating by peeking at your opponent's screen.
Purchase 3d Dual Play glasses
For a small percentage of the population, the viewing of stereoscopic 3D video technology may cause discomfort such as headaches, dizziness or nausea. If you experience any symptoms, discontinue using the 3D functionality and contact your health care provider.
