I went to see Jurassic World: Fallen Kingdom in 3D. When the 3D previews came on, I put my glasses on, but the image was wonky and kind of painful. After awhile, I went to go find someone to see if something was wrong with the projector, when I noticed a bin of 3D glasses outside the theater that looked different than mine. Turns out the guy who gave me glasses after I showed him my ticket gave me 3D IMAX glasses, and I needed the regular 3D glasses. I didn't know there were 2 types of glasses. Luckily, I figured all this out before the movie started.
