Understanding 3D Glasses / Technology


Understanding of 3D glasses / technology is possible not only after gleaning through its history but also the technological advances enabled by science. The advent of 3D movies in early 1950 started with crude glasses which resulted in grainy pictures, but thereafter the technology made leaps and bounds in the decade starting 1980 promoted in a big way by Disney and IMAX. Now advanced techniques enable color photography clearly show the background and characters in the 3rd. dimension enriching viewers with an unforgettable experience. Thus its comprehension is possible only when one understands the power of three dimensional technologies in movies. Quickly gaining popularity, 3D movies are greatly appreciated worldwide and are proving to be runaway successes at the box office.

Understanding 3D Glasses / Technology entails knowledge of motion photography viewed through various specialized lens which are of three types, firstly color filter 3D glasses, secondly, polarized 3D glasses and finally LCD shutter glasses. While the telescopic lens enables us to view heavenly bodies located far off in space, 3D images are created with the help of two different images which are independently and exclusively projected upon each eye which the human brain combines to produce the three dimensional effect. It is this comprehension of the technology which decodes the three dimensional effect puzzle. The 3D movie technology becomes magnificent only when the viewer uses 3D glasses which are the all important equipment. The outstanding picture quality can be appreciated only with the help of 3D glasses and it’s imperative to study the plethora of glasses available.

For understanding 3D glasses / technology it is crucial to know the types of special lens used to view the movies.  The first lens used to watch the 3D movies were the color filter glasses. They worked by putting up a distinctive color lens to each eye usually using lens combination such as green-red or green-blue thereby creating a special vision albeit grainy causing tension to the eyes. Thereafter came the polarized 3D lens which gave a good effect of three dimensional view by limiting the light ray from reaching the retina thereby generating the three dimensional effect. The polarized 3D lens involves two pictures pasted over each other which are sent through two different polarized lens in front of the eyes. Each polarized 3D lens contains a different filter which blocks the opposing polarized light in such a way as to deliver a different stereoscopic image to each eye which is not only comparatively cheap but also gives perfectly clear color picture.

One has also to study the LCD shutter glasses and their working for full understanding of 3D glasses / technology. Using advanced technology these glasses are a class apart. They allow the user to view images on the screen while the speedy refresh rate generates a three dimensional effect. Showing both left and right images these glasses flit across the screen at high speed. The most amazing feature of these glasses is undoubtedly the images that are shown in accordance, while the unwanted images are blocked and the others are shown. A veritable 3D image is fostered in the brain as the left eye sees the left picture and the right eye captures the right picture thus creating the 3D effect.

The best part nevertheless is the life like, steady and clear image thereby produced. What makes these LCD Shutter glasses supremely viable is their cheap cost. This leads to the conclusion that the magic animation technique photographed from two diverse angles giving viewers an illusion of reality is possible only with the application of special lens with which to view the movies.
