For linear polarized 3D glasses (0/90), the correct lens format (IMAX 3D system) should be: Left eye: 0 , Right eye: 90.

For linear polarized 3D glasses, the most popular specification that many 3D cinemas use is 45/135. But people sometimes do not know  which eye is 45, and which eye is 135? Pls look at the picture, and you will know that their correct position should be: Left eye: 45 , Right eye: 135.
