SONY moved to passive 3D a couple of years ago. You should just be able to use the 3D glasses from the cinema. Cheap as chips. 

You *may* find you need to rotate the lenses 45 degrees to eliminate purple ghosting. At least, this was true for LG 3D. The polarity was slightly different to the cinema glasses.....but work just fine.

I have a SONY Bravia and it works perfectly with the cinema glasses....and two pairs of passive 3D glasses came with it.
