What would you do? What would you say? Could you stand the pressure? Every week, find out how some of the smartest minds on the planet dealt with this situation as your host, Brady Forrest, highlights a different talk from Ignites around the world.//

A question for physicists out there....

I've been given a pair of polarized "3D movie" glasses to play with, but they've confused me.

If I put them on and look at my LCD (DELL E171FP ) monitor, the image on one eye is slightly different to the other. One's slightly browner, the other slightly greyer.

If I take the glasses off, and still looking from the "proper side" tilt them to and fro (clock/anti-clockwise) the effect is more pronounsed in both lenses...

I sort of expect that a bit, seeing as they're polarised and all

Now, the confusing bit. If I turn the glasses round (so the ear-hooks point towards the screen, and then repeat the to-and-fro motion the screen goes MUCH more dark (probably what I would have expected in the first place)... SO, how comes the lenses behave differently when viewing from one side to the other?
