3-D Movies

I watched Journey to the Center of the Earth last night in 3-D for the first time. Don't worry, I'm not going to tell you what happened. But, I will give you a warning and a very interesting thing to look forward to. In return, I'm hoping that someone can explain what happened to me because I'm really not sure I understand what was going on.

I remember when I was about 11 years old, I made my first pair of 3-D glasses. I'm hoping this makes me sound really intelligent. But if you've ever seen a pair of them before, I've already failed. All they are is a frame which holds two different colored lenses over your eyes. When I made a pair of them years ago, I used blue cellophane on one side and red on the other.

The movie came with 4 pairs of glasses. I found it interesting that they used green cellophane on one side and pink on the other. So, either the technology has changed over the years as far as the production of the movies, the colors don't really matter that much, or the colors used are closely enough related to the ones I'd used in the past. I'm really not sure. Anyone know?

But my main question really is on a different matter. When I'd used the glasses in the past to watch certain movies - and it only works with certain movies because they have to be produced in a particular manner. Again, I'm not going to act like I'm very well-informed on this. But, I'll share what information I do have as well as I know it. The scenes are filmed simultaneously from two different angles, one regularly and one at a 45-degree angle. Then, when produced, the films are superimposed.

When I watched the movies earlier in my life; one was a Jaws movie...the other was a Nightmare on Elm Street movie...you didn't have to wear the glasses all the way through. So, when the movie was over, I didn't have the same problems. It hurt my eyes. I had double-vision at times. At times I felt almost nauseous.

When I removed the glasses, I still felt like I was wearing them. Everything still seemed discolored and I still had the sensation of double-vision. The really cool thing was when I closed one eye at a time. The eye that had the green lens over it had a pink hue to my vision. And the eye that had the pink lens had a green hued appearance.

Obviously, the lenses didn't physically change my eyes. However, the perception had changed. My brain was trying to compensate for the lens, I believe.

It was like driving my bike without a windshield. After about an hour at speeds over 65 mph, my neck muscles attempt to compensate for the wind. When I'm stopped, if I turn my head to the side, then relax my neck muscles, my head naturally drifts back to the center.

Another example is standing in a doorway with your hands down at your sides. Then lift your arms up slightly and push on the door frame outwards for about 30 seconds. After that time, step out of the doorway and just relax your arms at your sides. Your arms will naturally drift upwards.

In both of those examples, the muscles are trying to compensate for the outside resistance. I assume my brain is attempting to do the same thing by changing my perception because of the change in the stimuli. But, I'm only guessing.
