Real D Circularly Polarized Glasses These are identical to the glasses you get in the Real D theatres. They are circularly polarized and work with our circularly polarized filters. Specifically for applications such as StereoGraphics Z-screen and Real D theatres. Works well with LG and other passive 3D stereoscopic displays and TVs.  However unlike ordinary Real D glasses these are recyclable.  The frames are made from a corn starch derivative so will disintegrate in landfills.  Under normal use they are very durable, they just won't be around for the next millennium.
