Answer :- In 3D movies, two images are projected simulta neously on the screen.
One image is horizontally polarised and the other is vertically polarised.
That is why, without 3D glasses, the image is blurred.
The 3D spectacles that we use essentially have two types of polaroid glasses, horizontally polarised for, say, the right eye and vertically polarised for the left eye.
