3D Glasses for 3-Eyed Aliens and Cyclops

My fiancee and I have some quite random conversations. The other night, we walked by an ad for the Toy Story 3D movies, and we started wondering about how the 3-eyed alien's 3D glasses would work if he was real. My brother later joined in on the conversation and he brought up the cyclops-monster Bob from Monsters vs. Aliens. We came up with some ideas, but I wanted to first pose the question to the IM department:

Assuming each creature is in a HUMAN 3D movie theater (i.e. 2 projectors in stereoscopic 3D or red-blue stereo), how do each creature's 3D glasses work? (Or do they work at all?)
