First thing you should know is what light polarity is. In addition to frequency, which we see as color, and intensity, which we see as brightness, a light wave also has polarity, which we cannot see. Roughly speaking, the polarity is the direction that the wave vibrates (up and down, side to side, at an angle, moving in a circle, etc.) as it moves forward toward your eye. Normal light is unpolarized, meaning some of it is polarized in any direction, which is why we never evolved the means to see polarity, there would be nothing to see.
The RealD technology, which is what they use for 3D movies currently, works by having two images that are circularly polarized in opposite directions (one clockwise, one counter-clockwise). The glasses have corresponding differently polarized lenses, so you see one image with one eye and the other image with the other eye. The projector moves at double speed, alternately projecting the images for the left and right eyes.
Unless you've recently purchased some expensive equipment, your computer screen and TV screen are not capable of producing polarized light and even if they were, your computer graphics card is not capable of processing 2 full quality images at once on the same screen. So you cannot use the RealD glasses for watching anything 3D at home currently.
All 3D technology works on that same basic principal, showing a different image to each eye, but there are significant differences in how they do it. The original 3D technology uses a red image and a blue image with corresponding red and blue glasses. Your computer and TV can display that just fine and if you get the red and blue lens glasses you can watch it, but the image doesn't look great and the color is a bit off. Nothing has been made for that technology in a long time and when they used to do it, the 3D camera technology wasn't very good. Regardless, your new 3D glasses are utterly useless for this.
There's a new system being sold now that aims the light from the screen in two different directions so that each eye sees a different image with no glasses at all. It's intended for use as a laptop monitor though because it only works if you're approximately 21 inches from the screen and roughly centered in front of it. They say 2 people can watch at one, but I don't really believe them.
There is some 3D technology out now and a lot more coming soon that will take advantage of your new 3D glasses. It'll cost you at least $600 to upgrade your PC (if your PC is powerful enough to handle the upgrade) in order to get the technology. A new system would be more like 3,000 for something pretty basic.
Eventually, HD3D will become the new home system standard, but so far there are few people with the equipment in their homes and there is limited content available. Since so many people bought new expensive HDTVs in the last few years, I think a lot of people will tend to wait a while before upgrading. Though HDTVs don't last as long as the old Standard Def CRTs, so in the next 7-10 years, it will become common. There are already 2 new networks just announced, including ESPN, which will soon begin broadcasting in 3D. But again, you'll need an HD3D TV to view it.
Also, Blu Ray Disc Association just announced a new 3D standard for movies that will be playable on any 3D technology. The disc will literally contain 2 full HD feature films, one for each eye, and then the monitor will take that input and display it using whatever technology it was built for. That way, 3D movies can be released before the industry settles on the best way to actually display 3D in the home, which will take a couple of years to figure out. Technically, you could watch that on your current TV if you have a player that will display the movie using the old red-blue system and you have corresponding glasses, but the quality wouldn't be the same.
