3D glasses are nothing new. In fact us oldies had them when we were young and probably didnt realise. Remember the ViewMasterT that showed all the cool Disney characters in full 3d? The ViewMasterT allowed you to look at two pictures of the same thing taken from a slightly different view point and tricked your brain into seeing one 3d image.

In order to see things in 3D each eye must see a slightly different picture.
This is done in your day to day life by your eyes being spaced apart so each eye has its own slightly different view.
The brain then puts the two pictures together to form one 3D image that has depth to it.
Since your eyes are a couple of inches apart, they see the same image but from slightly different angles. Your brain then correlates these two images in order to gauge distance. This is called binocular vision.
Modern 3D movies are filmed using two cameras filming the same image from slightly different positions to create these images. Your eyes can guage these images automatically because each eye sees only one of the images. A 3D film viewed without glasses is a strange sight and may appear to be out of focus, fuzzy or out of register. Because the same image is projected simultaneously from two different angles in two different colours, red and cyan (or blue or green). Heres where those cool glasses come in -- the coloured filters separate the two different images so each image only enters one eye. Your brain puts the two pictures back together and now youre dodging a flying meteor!
Wearing 3d glasses makes the movie or television show youre watching look like a real scene thats happening right in front of you and like youre a part of the action - not just someone sitting there watching a movie. About Active Shutter 3D glasses.
Active shutter glasses commonly used in modern 3D television sets are glasses used with a display screen to create an illusion of 3D images. Each separate lens contains a liquid crystal layer which becomes dark when a voltage is applied. The glasses are activated by an infrared transmitter which sends a timed signal allowing the glasses to darken alternately in synchronisation with the refresh rate of the television set or screen being watched. At the same time as this the display shows a different perspective for each eye and when used together gives the wearer the desired 3D image.
The advantages of active shutter glasses such as those seen here include eliminating ghosting which can be a problem with other 3D systems. They also have the advantage of being colour neutral unlike the red/blue filter systems meaning the complete colour spectrum can be viewed. Our 3D glasses can be worn over most prescription glasses.
