2D Glasses

Maybe you're one of the millions of people who experience physical discomfort while watching 3D movies, or perhaps you've just got 3D fatigue. Either way, there's finally something you can do about it. Within every 3D movie is a pair of 2D movies, each recorded from a slightly different perspective. Most 3D glasses use polarized lenses to direct a different stream to each eye, giving the impression of 3D. For $10, the clever folks at 2d-glasses.com will send you theater-ready specs that eliminate one of these channels entirely, directing one channel to both eyes and turning a 3D movie into 2D. Or, with two pairs of 3D glasses from your local multiplex and a little handiwork, you can make a zero-cost headache-free pair of your own.
