3D could ruin your depth perception

That's the problem. When the movie's over, and you take your glasses off, your brain is still ignoring all those depth perception cues. It'll come back to normal, eventually. Some people will snap right back. In others, it might take a few hours. This condition, known as 'binocular dysphoria', is the price you pay for cheating your brain into believing the illusion of 3D. Until someone invents some other form of 3D projection (many have tried, no one has really succeeded), binocular dysphoria will be part of the experience.

It's probably the glasses. What more uncomfortable can you get? My eyes felt like they were going to explode.

If they could figure out how to layer a screen in a 3 dimensional manner without eye-wear. Now that would definitely be pretty cool.

Makes me think twice about going to see Alice and Wonderland, lol

Iv heard rumors for awhile that they were working on 3d without the glasses.

I think I'll stick to a traditional theater viewing, or the occasional Imax.

And there's no way 3-D television sets are going to be successful either. Maybe to a serious tech enthusiast or just a "look what I got" piece.

Due to eye issues, I live in a 2 dimensional world visually... Ironically, a 3D movie is the only time I see clearly in 3 dimensions. I find it a very interesting and fun experience.
