2D glasses for 3D movies
So here’s the idea: Take two sets of 3D glasses and remove the left lens from one and the right lens from the other, and swap them into the other pair of glasses. So one pair now had two left lenses, and the other two right lenses.
Why would you want to do this? If you’re one of those people for whom the whole 3D movie experience is a bit meh, or you actually find it annoying or disorienting, you can still go to a 3D movie with your friends and wear your new 2D glasses. You now get the same image in each eye, exactly like a regular 2D movie! And without the double-vision effect of just watching the movie without glasses. So you can sit back and watch the movie in glorious 2D while your friends next to you watch in 3D.
Even better, you can successfully argue to the ticket sales counter that you are only watching half the movie, so you should only have to pay half price!
