2D Glasses kick 3D to the curb

Not everyone is in love with the 3D phenomenon. Sensitive viewers can slap on a set of special 2D Glasses and convert those pesky 3D movies back into 2D.

2D Glasses
Buddy Holly, your 2D Glasses are ready. 2D Glasses

There's that awful moment when your excitement at going to the theater is ruined by your spouse's announcement that a 3D flick is on the menu.

Thanks to a clever invention, your day off from Netflix doesn't have to be a nausea-inducing nightmare.

A certain percentage of the population isn't onboard with 3D. It can cause nausea and headaches in some people. How much of that is due to the 3D technology and how much has to do with crummy filmmaking is a discussion for another time.

It all started with "Tron: Legacy." Inventor Hank Green created 2D Glasses so that his wife could go along to see 3D movies with him and avoid the bad headaches.

There is a fairly simple concept at work here. 3D movies project two different images simultaneously. Regular 3D glasses block out a different image on each lens, tricking your brain into seeing 3D. Green's $7.99 2D glasses block out the same image on each lens, bringing the film back into 2D for the viewer. They work on any film in the RealD 3D format.

The glasses themselves wouldn't look out of place on Buddy Holly and could probably pull double-duty for a Blues Brothers costume. They are designed to look almost identical to the regular 3D glasses offered at theaters, so you can blend into the crowd.

Even if you bring your own 2D Glasses to the theater, you'll still have to shell out for the 3D up-charge. Surely, your 3D-loving spouse is worth it.
