When I went to see Avatar over the weekend, we were given different 3d glasses to the ones we’ve had before. They weren’t the usual passive polarized glasses, and they didn’t look like the active glasses you get for home cinema.
The glasses had pretty reflective lenses, and looked more like mirror shades. Also, when the cinema wasn’t showing a 3D movie, the right hand lens went completely opaque
How do they work?

It essentially works by having two sets of slightly off projections or images being displayed over one another that have different 2d perspectives, the same as your eyes. One “lens” will filter one of those images/projections, while the other filters out the other image/projection. Your eyes will take in these two different images from each eye and your brain will process it into a perceived 3D image. This applies to both types of 3D glasses(polarized or colored).
