With the launching of digitally organized 3D films, like the "Avatar", we cannot help but want for more. 3D films take us to the next level of viewing experience that is really exciting. But we can also watch these 3D films at home, with the use of a 3D DVD player, a 3D applicable television and 3D movie glasses.

3D movie glasses are not only being handed out in theaters for your movie viewing; they are also available in many stores that sell 3D-capable television sets and 3D DVD players. Some are even included in television sets when you buy three dimensional DVD players or TV converters. Some of the 3D movie glasses included in these sets operates via infrared.

But how do these movie glasses work? Actually, they are not something new. They have been around for a century since 3D filming started. Several decades ago when 3D films were first released, 3D glasses were already being used. The 3D films then are not as popular as today as the technology was not as good.

Twenty years ago, we were able to view 3D pictures of Disney characters through the View Master™. The View Master™ makes use of a depth illusion to trick us into seeing 3D images. There are actually two pictures of the same image, each of them angled slightly. Even though there are two images, we will not be confused since each eye is seeing a different image, which will then be correlated in the brain - creating a 3D image.

Although 3D movies are not shown in two screens or two pictures, it employs the same concept. They make use of anaglyphic images made up of two separate images superimposed on each other. Each of the images is angled slightly for the benefit of one of our eyes. We cannot see the difference in if we look at them with bare eyes; hence 3D movie glasses are important. These glasses allow filtration of images, making only one image enter one side of the pair of glasses.

There are two types of 3D movie glasses available today - the polarized 3D glasses and the red and blue lens filter. Each lens of the polarized 3D movie glasses is polarized in a different way than the other, and accepts only one image out of the two that comes from the 3D polarized video being shown. The red and blue lens filter works in a similar way, except that it makes use of red and blue lens and an anaglyphic video.

Indeed, 3D movie glasses will definitely boost our movie viewing pleasure.
