I'm going to see Avatar in 3D tonight...
Does the movie use red and blue lenses or polarized glasses?
The reason I ask is I have a pair of bad azz polarized glasses I can bring if it is polarized.
I found this on yahoo answers:
For regular 3-D, the black polarized glasses will be used. They're the ones that look like plastic sunglasses. If you're stumped by this information, I provided a link:

For the IMAX, they are also polarized, but slightly distorted.
