When it comes to waching 3D television, movies or playing games - our eyes see 2D images since there is no perception of depth. However, if you think about it, in the real world we see everything in 3D which includes length, adepth without realizing that this is even a gift that was given to us by god. During these days, 3D TV can be watched by using a pair of either passive or active 3d glasses and there is even technology being developed to produce 3D glasses free television sets.

The 3rd dimension is achieved through 3D glasses. In order to view things in 3D, you must achieve different views in your eyes, where our brain receives signal from both eyes to interpret the depth of 3rd dimension. The way 3D glasses work is by presenting stereoscopic vision. Each one of your eyes gets a unique and slightly different image on the TV screen where images are being shown. Our brains attempt to get the inputs eyes to get a sense of depth. Otherwise, without wearing 3D glasses all you would see is a blurry image (at theatres like IMAX).

Today, there are different types of 3D glasses that are available to the consumers, and not every set is compatible with every 3D TV. Therefore you should do your research on buying 3D glasses to compare the differences between active shutter and passive technology to figure out the right option for you.
