Remember seeing 3D movies with flimsy cardboard glasses? If that's your recollection of 3D movies, get ready for some big changes. Today's 3D glasses are made of plastic and cost as much as $50 each. Movies like Avatar are making the glasses popular. Right now there are four companies fighting for a share of the market, according to this story from The New York Times. The players:
- RealD, which makes disposable glasses (the company touts them as being recyclable) that cost about 65 cents each, according to the NYT report;
- MasterImage 3D, which offers both single-use and multiple-use glasses (the company says the single-use glasses can be washed and reused several times;
- Dolby Laboratories, which makes higher-tech glasses that cost about $28 each; and
- XpanD, which makes glasses that "use battery-powered LCD shutters that open and shut so each eye sees the appropriate frame of the movie," according to the story. Those glasses cost up to $50.
