Understand 3D glasses

There are two different types of 3D glasses, active and passive, and the type of glasses you use for your TV depends on what type of 3D your TV displays.

Passive (polarized)

Passive glasses are polarized and are designed to block different amounts of light to each eye to create the illusion of depth. Because of the simplicity of the lenses, these 3D glasses don’t require batteries or recharging, and are often much less expensive than active-shutter glasses. LG Cinema 3D passive glasses are also available in clip-on format (sold separately), allowing anyone wearing corrective lenses to enjoy 3D entertainment without having to wear two pairs of glasses.

Active (shutter)

Active-shutter glasses work by communicating wirelessly to your TV through a built-in emitter. Each lens is essentially a mini LCD screen that actively lightens and darkens with the 3D content. LG active-shutter glasses use rechargeable batteries that you can charge by simply plugging them into the USB port on your TV.

You can purchase active-shutter glasses from a number of electronics retailers. Just be sure to get the correct glasses based on the model release date of your TV.

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.
