Nowadays we see people wearing 3D glasses everywhere. One can see them in a park worn by people taking their pets for a tour. Not only in parks but you see people wearing them in restaurants and in fast food booths. You may wonder what they do. Why people wear them? You may see people also wearing them while using computer or while watching TV? Is it making the image 3D instead of making it 2D? An active 3D glass is a big title so what has made them earns it?
The human brain needs two images of an object to calculate where is it in the three dimensions world. The active 3D glasses do the job by giving the human brain double image of every object seen through them. As a result, the human brain calculates and puts the image in 3D mode. In the world of 3D movies and 3D computing, what is shown is only colors and lines? All the glasses do is to show the two parts through cooperation with the display which displays the two objects (the colors and lines in two different places). What makes something looks as if it is going to jump out of the screen? What causes you to see that something on the screen is 3D? The idea is that the display and the glasses work together to make the right eye see one thing and the left eye see the other. This provides the human brain with double image causing you to imagine that it is 3D. The screen has to show the image in two different ways and your eyes have to catch one of them.
The collection of active glasses, if you own them, requires charge to operate. You will have to recharge your active 3D glasses in order to use them as they require power to operate and generate double images. The function of the 3D glasses that requires power is that they alternate showing images blocking one and showing the other at the same rate of your computer or TV screen. Frames are being shown for one eye and the other alternating at the same frame rate through blacking one lens after another.
The Active 3D glasses work in cooperation with the TV or the computer screen to fake you and give you the impression of watching three dimensional objects move in front of your eyes.
