An active shutter 3D system is a technique of displaying stereoscopic 3D images. It works by only presenting the image intended for the left eye while blocking the right eye's view,

Active glasses are made of LCD shutter lenses that run on battery(s). The 3D video footage is presented at 120 times per second, a left image and a right image flickers on the screen. In perfect coordination with this, the lenses in the active shutter LCD glasses turn from opaque to transparent.
