Do I need special glasses to view 3D programming?
Special glasses are required to view 3D programming. They are what let you see and experience the 3rd dimension of depth.
How do 3D glasses work?
Glasses designed for 3D viewing use something called active shutter technology—alternating left eye/right eye blocking—to sync up with your 3D TV and merge two images into one so you get that 3rd dimension depth. Your brain actually does the merging, but the active shutter glasses make it happen.
Where do I get the 3D glasses?
Typically you get one or more pairs of 3D glasses with your 3D-enabled TV, or you can purchase them as an accessory. If you do purchase extra pairs of 3D glasses separately, it's very important that you get the ones that work with your specific 3D TV. Buy the same brand of 3D glasses.
