Most movie theaters use RealD 3D glasses. These are passive 3D glasses, and they'll also work with your home 3D system — as long as your system supports passive 3D technology. Passive technology refers to technology that doesn't require an external power supply. Active 3D technology is more common in home theater systems, but if you do happen to have a passive 3D television or projector, you can use the 3D glasses you get at the movie theater. That said, movie theater 3D glasses won't work with every monitor or TV, so check the details of the technology you have in your home to know for sure.
