The Awesome 3D Glasses

With the recent rise in the number of movies that use 3D glasses, a lot of people are asking, including the younger generation, how are 3D glasses made and how do they work. It’s a very simple and fascinating question with various ways of answering it.

3 dimensional glasses or 3D glasses follow the principle of stereoscopy where various techniques are applied in order to provide the human eye the necessary depth of perception needed to form a “lifelike” movie viewing experience. One thing people should note is that 3D glasses will only work on anaglyph types of photos, anaglyph images are images that are made up of two color layers, superimposed and offset. The picture also contains two differently filtered colored images, one for each eye.

3D Glasses themselves are categorized into two types, active and passive. LCD shutter glasses are considered the active type of 3D glasses. Passive 3D glasses are the more common types and are usually also referred to as Polarized 3D glasses. Glasses under the passive category are created using low cost glasses fitted with polarized lenses of two different chromatic colors and reacts perfectly with anaglyph pictures.

Nowadays, even kids can make their own 3D glasses. All they need are several strips of cellophane as well as used glasses. It is important to remember however, that the right side should have the color red while the left eye should get the cyan colored cellophane. Getting the colors wrong on the 3D glasses will result in getting the image wrong.

3D glasses are currently in high demand thanks to the current trends not only the way movies are produced but also by technology. Various electronic companies are now slowly seeing the bigger picture and the huge return of investment on 3D technology. Samsung among many others has unveiled a new home entertainment system that works on 3D technology along, making use of 3D glasses in order to bring new life.
