When you think at a 3D TV you may think that it is something you would like to buy for sure, but if you think twice then you see some problems with it. Firstly, you have to wear glasses that may cause your eyes to tire faster. And this is not the only issue with the 3D TV. Lack of media to be played on these screens and their price prevent buyers to get 3d screens instead of normal ones.
3D TVs got a huge media coverage, and all people seem to want to watch 3d movies at cinema instead digital ones. A lof of technologies were developed but it is still not the time to buy a 3d tv.
The biggest problem is the price, you can’t pay 5k$ only to watch few movies that are available on 3D.
