My wife was unable to see the 3D effects on Flight of Passage this morning because of the particular shape of the frames. (This wasn't the loose fit problem that many have had, but because she needs to have the 3D glasses right up against her regular glasses in order for the effect to work.) Wondering if the 3D technology for FoP is the same as for one or more of the other 3D attractions at WDW. We could borrow a pair (and yes, return it when going back to that park) to wear on FoP. Everything else seems to work all right for her, because the frames are rather simple in their shape. Assuming they all use some form of polarization splitting, but that doesn't mean that they use the *same* polarization. If you use the wrong one, it could just cause a headache. Thanks for any technical insights here.
