^{3D Glasses For Newer Imax Theatres}

These are special 3D glasses with linear polarizers are in 0/90 orientation not 45/135.  Most newer Imax 3D Theatres use this orientation but you my want to check with the specific theatre before ordering.  They are larger than most 3D glasses to cover the large Imax screen.  A few  theatres still use 45/135 (standard linear polarized glasses) especially in Europe.
